Proper tire selection, application and maintenance
continue to be the most important factors in earthmoving
economics. Wheel tractors, loaders, scrapers, trucks, motor
graders, etc. are earthmoving equipment whose productivity and payload unit cost may depend more on tire performance than any other factor.
Off-the-road tires must operate under a wide variety of
conditions ranging from dry “potato dirt” through wet
severe shot rock. Speed conditions vary from less than
1 mph average to 72 km/h (45 mph). Gradients may vary
from 75% favorable to 30% adverse. Climatic conditions,
operator skills, maintenance practices, etc. all may have
a profound effect on tire life and unit costs.
Although one specific tire construction may be acceptable in a variety of applications, no one tire can meet all
requirements on any one machine and perhaps not even
one job. The many differences in tire requirements on
earthmoving machines have resulted in a wide variety of
tread and casing designs being made available. The optimum tire selection for a specific machine on a given job
should be a joint decision between the user and tire supplier. Several tire manufacturers have technical and application representatives in the field for proper guidance in
tire selection.
When job conditions change, it may be desirable to
select a different tire configuration to meet the new
requirements.

Tire Construction
● Bias Ply
TIRE CONSTRUCTION
The pneumatic tire is essentially a flexible pressure
vessel utilizing structural members (nylon, steel cable, etc.)
to contain the hoop tension resulting from the inflation
pressure. Rubber is utilized as a protective coating and
sealant over the structural members and makes up the
tread pattern which provides the wearing medium at the
ground interface. The following brief explanation of the
various tire constructions will assist you in selecting tires
for your specific application.
Two distinct tire constructions approved on all Cat®
machines are the BIAS PLY and RADIAL PLY tires.
Radial tires are designated by an “R” while a “-” represents
a Bias constructed tire. For example, a 45/65-45 tire
would be of Bias construction and a 45/65R45 would be of
Radial construction. The following is a brief explanation
of the principal features of these two constructions.
Bias Ply
1. Beads – The tire beads consist of steel wirebundles
(3 or 4 in larger tires) which are forced laterally by tire
inflation pressure to wedge the tire firmly on the rim’s
tapered bead seat. The nylon plies tie into the bead
bundles. The forces inherent in the tire are transmitted
from the rim through the bead bundles into the
nylon.
2. Body plies – Layers of rubber-cushioned nylon cord
comprise the tire casing. Alternating plies of cord
cross the tread centerline at an angle (bias). The term
“ply rating” is an index of tire strength and not the
actual number of tire plies.
32-2
Bias Ply Construction
3. Breakers or tread plies – These, if used, are confined
to the tire’s tread area and are intended to improve
casing strength and provide additional protection to
the body plies. Some “work” tires employ steel breakers
or belts to further protect the casing.
4. Sidewalls – These are the protective rubber layers
covering the body plies in the sidewall.
5. Tread – The wearing part of the tire that contacts the
ground. It transmits the machine weight to the ground
and provides traction and flotation.
6. Inner liner – This is the sealing medium that retains
the air and, combined with the “O” ring seal and rim
base, eliminates the need for inner tubes and flaps.
7. Tubes and flaps (not shown) – Required if the tire is
not of tubeless construction with an inner liner.
8. Undertread – Protective rubber cushion lying between
tread and body ply.

Tires
TIRE TYPES
Off-the-road tires are classified by application in one
of the following three categories:
1. Transport tire – For earthmoving machines that
transport material such as trucks and wheel tractors.
2. Work tire – Normally applied to slow moving earthmoving machines such as graders and loaders.
3. Load and carry – Wheel loaders engaged in transporting
as well as digging.
TIRE SIZE NOMENCLATURE
Radial Ply Construction
1. Beads – A single bead bundle of steel cables or steel
strip (spiraled like a clock spring) comprise the bead
at each rim interface.
2. Radial casing – This consists of a single layer or ply
of steel cables laid archwise (on the radian) bead to
bead.
3. Belts – Several layers or plies of steel cable form the
belts which underlie the tread area around the tire
circumference. The cable in each belt crosses the
tread centerline at an angle with the angle being
reversed from the preceding belt.
4. Sidewalls.
5. Tread.
6. Undertread – Protective rubber cushion lying between
tread and steel belts.

1. A wide base tire has a section height to section width
ratio in the range of 0.83. As an example, a 29.5-25 tire
has an approximate cross section width of 749 mm
(29.5") (first number) and a rim diameter of 635 mm
(25") (second number).
2. A conventional tire has a section height to section
width ratio in the range of 0.96. As an example, a
24.00R35 tire has an approximate cross section width
of 610 mm (24") (first number) and a rim diameter
of 889 mm (35") (second number).
3. A low profile tire has a section height to section width
ratio in the range of 0.65. As an example, a 45/65-45
tire has an approximate cross section width of 1143 mm
(45") (first number), a 65% aspect ratio designated as
65 (second number), and a rim diameter of 1143 mm
(45") (third number).
If designated 45/65 R39, then the R denotes radial
construction.
When comparing a wide base tire to a standard base
tire, a larger first number on a wide base tire with the same
rim diameter does not mean the wide base is larger in
overall diameter. For example, the 18.00-25 conventional
tire is larger in diameter than the 20.5-25 wide base tire.
The 18.00-25 is comparable in overall diameter to the
23.5-25 wide base tire.

Tire size nomenclature is derived from the approximate
cross section width and rim diameter typically in the
format of Tire Width, Aspect Ratio, and Rim Diameter
(example: 45/65-45). Available tire types include:

CODE IDENTIFICATION FOR
OFF-HIGHWAY TIRES
The tire industry has adopted a code identification
system to be used for off-the-road tires. This identification
system will reduce the confusion caused by the trade
names for each type of tire offered by each tire manufacturer. The industry code identification is divided into six
main categories by types of service as follows:
C — Compactor Service
E — Earthmover Service
G — Grader Service
L — Loader and Dozer Service
LS — Log-Skidder Service
F — Industrial
R — Agricultural Tractor
I — Agricultural Implement

RADIAL TIRE IDENTIFICATION
Code Identification for Michelin Tires
All Michelin earthmover tires are radial construction,
designated by the “X” marking. They contain a single
steel radial ply with a series of steel belts placed around
the tire’s circumference which reinforce and stabilize the
tread.
Following are the tread designs currently available
from Michelin with the different internal constructions
depending on the application.
Type A4
Particularly resistant to cuts, tread tearing
and abrasion on very rough surfaces.
Type A
Particularly resistant to cuts, tread tearing
and abrasion at average speeds which are
higher than those for A4 (above).
Type B4 Compromise solution between abrasion resistance and average speed on rough surfaces
(available in sizes 49 inch rim diameter and
above).
Type B
Higher resistance to internal heat generation on surfaces which are not particularly
rough.
Type C4 For running on long cycles at high speeds on
well maintained roads.
Type C
Very high resistance to high average speeds
on long cycles run on well maintained roads.

Since Michelin radial tires contain a single steel casing
ply, they utilize the industry method of designating
radial tire strength in terms of “stars.” Their system
consists of a one star, two star, and three star rating as
an indication of the tire’s carrying capacity. The one star
is the lightest construction, generally used on work and
slow moving transport machines. Two star tires are used
on most medium and high speed transport machines.
Three star construction provides the greatest carrying
capacity for a given size and is only available in small
standard base tires.
This combination of tread designs and types of construction provides a range of radial tires which cover
most earthmoving applications. We recommend that in
applying steel radial tires to your machines you provide
all site condition data to the tire manufacturer. Obtain
their recommendations as to which tire will provide the
most economical operation.

Radial Tire Identification
● Goodyear
Code Identification for Goodyear Radial Tires
All Goodyear steel radial earthmover tires have been
designated Unisteel followed by a three or four digit
alpha-numeric code that identifies the particular tread.
For example, for a RL-2+, RL stands for Rock Lug and
indicates that the upper sidewall has rock protection.
The number in the code corresponds to the tire industry
identification system (2-traction, 3-rock, etc). The fourth
digit, if any, is used to designate tread design differences
for the same basic tread type.

A star rating system instead of the ply rating system
indicates the casing strength of radial tires. These symbols
indicate the recommended inflation for a particular tire
load. Following the star rating code is Goodyear’s Custom
Compound and Construction code. For a tire designated
“2S” the 2 indicates a heat resistant compound and the S
indicates standard construction. The higher the number
the greater the abrasion and cut resistance with a corresponding lower TKPH/TMPH rating.

The casing strength, i.e., load carrying capacity of tire
is indicated by star rating system; 1-star, 2-star and
3-star. Bridgestone’s Off-the-Road tires are designed and
produced to meet the commonly accepted international
standards, those set by the TRA (Tire and Rim Association) in the U.S.A., by the ETRTO (European Tire and
Rim Technical Organization) in Europe and/or by the
JATMA (Japan Automobile Tire Manufacturers’ Association) in Japan. Where differences exist between the
TRA, ETRTO and JATMA standards, Bridgestone selects
the most appropriate.

Tires
Ton-Kilometer Per Hour Rating System
TON-KILOMETER PER HOUR (TKPH)
Tire selection and machine operating practices have,
in some cases, become the critical factors in the over-all
success of earthmoving ventures. One of the most serious
problems occur when tires are operated at temperatures
above their capabilities. Separation and related failures
occur. To help you avoid temperature related failures,
Caterpillar has been instrumental in developing the TonKilometer Per Hour (TKPH), also known as Ton-Mile
Per Hour (TMPH), method of rating tires. The formula
to convert a TKPH rating to a TMPH rating is:
TMPH = TKPH × 0.685
Heat and Tire Failure
Tire manufacturing requires heat in the vulcanizing
process converting crude rubber and additives into a
homogeneous compound. The heat required is typically
above 132° C (270° F).
A tire also generates heat as it rolls and flexes. Heat
generated faster than it can be radiated into the atmosphere
gradually builds within the tire and reaches maximum
level at the outermost ply or belt.
Over time, enough heat can develop from overflexing
to actually reverse the vulcanizing process or “revert”
the rubber causing ply separation and tire failure. Only
a brief time at reversion temperature initiates the failure.
Experience shows that few pure heat separation cases
occur. Most so-called heat separations are in tires operating
below the reversion level.
As a tire’s operating temperature increases the rubber
and textiles within significantly lose strength. The tire
becomes more susceptible to failures from cornering,
braking, impact, cut through, fatigue and heat separation.
If operating tires at higher temperatures is absolutely
necessary, it is essential the machines be operated to
reduce the probability of premature tire failure. No hard
cornering without superelevation, no panic braking, etc.
The TKPH formula was developed to predict tire
temperature buildup. The system is a method of rating
tires in proportion to the amount of work they can do
from a temperature standpoint. It utilizes the product of
load × speed to derive an index of the tire temperature
buildup. Even at or below a tire’s TKPH, failures may be
initiated by overstressing the tires.
32-18
It is possible by using a needle type pyrometer to measure
temperature at any desired point within the tire casing.
However, the instrumentation and the technique does
not lend itself to general field use. The greatest difficulty
is locating the thickest (therefore the hottest) tread bar
in any given tire using giant calipers. The tire must then
be drilled along the centerline of this bar from shoulder
to shoulder at 52 mm (2") intervals. These 3.18 mm
(1/8") diameter holes extend down through the tread and
undertread to the topmost reinforcement. This procedure
is fully described under SAE Recommended practice
J1015.
The TKPH rating system as given in this SAE specification is approved by most tire manufacturers. Michelin, in
addition to providing TKPH ratings has developed their
own speed/load carrying rating system and we recommend
that Michelin be consulted where high tire temperatures are
a concern.
Heat generation in a specific tire at recommended
pressure depends on three factors:
● the weight the tire is carrying (flex per revolution),
● the speed the tire is traveling over the ground (flexures
over a period of time), and
● the air temperature surrounding the tire (ambient
temperature) and road surface temperature.
Once a tire manufacturer has determined a tire’s temperature characteristics and expressed them in TKPH,
the above listed specific job conditions can be used to
determine any tire’s maximum work capacity. These
conditions provide on site ability to predict and avoid
costly tire separations.

The tire TKPH can be matched to the site TKPH as
well as compared with TKPH values of different makes
and types of tires.

Total Hours (in the shift)
For excessive haul length (32 kilometers or more)
consult your tire representative for modification to the
TKPH value.
To use in the United States Customary System, change
kilometers to miles and use short tons.
It should be noted that prolonged operation at high
casing temperatures can fatigue the nylon at the flex
points in the sidewalls.
The following are the most recent TKPH ratings as
made available by Goodyear, Michelin and Bridgestone,
and are subject to change on their part at any time.
Other tire manufacturers’ TKPH ratings will be included
in future handbook editions when and if made available.
For latest TKPH ratings, consult specific tire manufacturer
at time of machine and/or tire purchase.
Tires
Load-and-Carry TKPH
The wheel loader, when used in load-and-carry applications, may encounter temperature problems similar to
those normally associated only with tires on scrapers,
trucks and wagons. Do not place the vehicle in load-andcarry applications without first consulting the tire manufacturer, or obtaining maximum load and speed ratings and
pressure recommendations from the tire manufacturer.
Conventional and Radial Steel Cord Tire Options
Tire options now provide types to operate in conditions
ranging from rock and abrasive materials, to jobs with
high speed hauls in good materials.
The best tire type can be different for the drive tires
than for other tires on the same machine. TKPH should
be calculated for all tires.
TIRE DRIVE-AWAY RECOMMENDATIONS
Heat separation can be a problem during machine
delivery and moving machines from one job to another.
Whenever roading earthmoving machines, check your
supplier for the tire manufacturer’s recommended speed
limitations on the specific tires involved.
Some tire manufacturers also recommend that vehicles
equipped with extra tread depth or special compounded
tires should not be roaded without their specific approval.
Our tests support this recommendation, especially for
L-3, L-4, E-4 and L-5 tires.

Tire and Rim Association Ratings
Tire Selection
TIRE AND RIM ASSOCIATION RATINGS
While the TKPH Rating System provides a method to
determine the tire’s work capacity, Tire and Rim Association Ratings provide a guide for evaluating a tire’s
structural capacity. These two rating systems should be
used in conjunction to evaluate tire performance.
TIRE SELECTION
Selecting the optimum tire for a given application is
particularly critical for earthmoving. The machines have
the capability to outperform the tires and, unless proper
practices are observed, very costly premature tire failures
can occur. Job conditions vary greatly throughout the
world, as well as within any given job site, and selecting
the optimum tire requires careful consideration of all
factors involved. In general, the tire manufacturer should
be consulted before making the selection for any given
application. In some cases, the tire manufacturer can
fabricate tires specifically tailored for a given job site.
For those applications where wear is extremely slow,
especially as a result of only occasional operation throughout the year, the cheapest lightweight tire needs to be given
strong consideration.
As job conditions become severe, the following factors
should be evaluated in selecting a tire:
Transport or Load-and-carry —
● TKPH (primary consideration)
● Minimum approved star/ply rating or greater
● Largest optional size
● Thickest tread commensurate with TKPH
● Most cut resistant tread commensurate with TKPH
● Belted construction
Grader —
● Tire load rating suitable for maximum equipped
machine weight (See Tire Load Worksheet on
next page)
● Application specific tire (snow, construction,
road maintenance, mining, general purpose, all
season)
● Bias or radial based on initial cost, puncture resistance, rolling resistance, life to retread/repair
Loader or Dozer —
● Minimum approved ply rating or greater
● Largest optional size
● Thickest tread
● Thickest available undertread
● Buttressed shoulder
● Most cut resistant tread
● Belted construction
● Lowest aspect ratio
All tires should be operated at the tire manufacturer’s
recommended inflation pressure for a given application.
Inflation pressure should be checked every working day
with an accurate gauge. This gauge should be checked
against a known standard such as a dead weight tester
at least once a month.
Excess loads may result from factors such as varying
material density, field modifications to equipment, mud
accumulation, load transfer, etc. Only under these conditions may the actual in service tire load exceed the rated
machine load. When excess loads are encountered, cold
inflation pressures must be increased to compensate for
higher loads. Increase tire inflation pressure 2% for each
1% increase in load.
Bias Ply
Radial Ply
Maximum
Excess
Load
Pressure
15%
30%
7%
14%
The above loads will result in reduced tire performance and must be approved by the tire manufacturer.
The use of chains is difficult to justify except under a
few conditions. Chains are very costly and heavy, and
require more maintenance than most operations can
provide. On some models sufficient clearance does not
exist for chains with all tire combinations. Extensive
modifications may be required if chains are needed for
the job.
Foam filling tires is normally not recommended due
to high cost and lack of local filling facilities. Its use
should be confined to loader and dozer applications
where penetrations occur almost daily. If foam is used
be sure to adhere to recommended equivalent pressures
of nitrogen and use highest available ply rating. Consult
tire manufacturer for specific warranty concerns.

F Summary
– Choose a tire with a rated load capacity equal to or greater than the controlling tire weight = Tire rating > (1f)
– Attachments may cause the maximum weight per tire to exceed tire capacity. In these cases the tire supplier should be consulted.
– Contact your tire supplier for machine specific inflation pressures to ensure compensation for different tire loads.

The following tables present commonly found
Caterpillar and the tire suppliers’ recommended cold
inflation pressures for tires on Cat machines. For inflation
pressures of tire suppliers not listed please obtain them
directly from the respected supplier.
The inflation pressure is based on a ready-to-work
vehicle weight, rated payload, and average operating
conditions. Pressures for each application may need to
be varied from those shown and should always be obtained
from your tire supplier.
Pressures for all tires apply to rib, traction, rock,
deep tread, and super deep tread tires.
NOTE: Caterpillar recommends using dry nitrogen
(N 2) gas for both tire inflation and pressure
adjustments on all current and past production
machines.

NOTE: Ballast weight for bias ply tires from Goodyear data, radial ply weights from Michelin data. Contact your tire supplier for additional information. Under
abnormal tire wear conditions, ballasting of rear tires may be desirable. Ballasting of front tires also should only be done where extremely rapid tire
wear rates are encountered. Excessive weight will reduce machine performance.
NOTE: Fillage beyond 75% of tire enclosed volume is not recommended. With liquid ballasting, inflation pressure must be checked at least once per day.
NOTE: 1.6 kg (31⁄2 lb) Calcium Chloride per gallon water. Solution weighs 4.6 kg (10.15 lb) per gallon.
NOTE: Total machine mass including all attachments in operating condition, all reservoirs at full capacity and ballasted tires must not exceed certification mass
listed on the ROPS certification label.
NOTE: Special air to water valves are required for liquid filled tires.
