TECHNICAL INFORMATION
Rims:
For optimal performance, respect recommended rim widths.
Rolling direction:
Some wet tires have a directional tread pattern. Slick tires are nondirectional.
Pressures:
Tire pressures are always a function of three parameters: vehicle type
and setup, tire type, and track conditions (track temperature, average speed, presence
of banked corners, etc.). Pressure needs to be optimized for each individual case.
Visit our website, michelin.com/motorsports, or call our Michelin Race Tire Distributors
or Michelin Consumer Care for more information.
MICHELIN competition tires are not homologated for road use.
They must be used only on tracks or for racing according to
Michelin recommendations.

In order to ensure the highest level of performance at all times,
Michelin is constantly developing its range and reserves the right to
introduce modifications in the course of the season.

COMPETITION TIRE MEASUREMENTS
One of the advantages of the MICHELIN racing slick’s radial construction is dimensional consistency. Most teams will find over time that there is no
need to measure rollout as tires are changed. Once you have established the optimum setup for your car at a given track, this benefit will minimize
changes due to tire irregularities. MICHELIN racing slicks are currently offered in the following sizes.

SAFETY GUIDELINES Michelin Group
1 – INTRODUCTION
• Proper positioning of the tire on the vehicle (left, right, front, rear).
We recommend that you follow the safety guidelines provided below.
• Proper working pressure.
These guidelines apply upon satisfaction of any more stringent regulatory
requirements, developed or prescribed by competition, track, series or
circuit organizers with respect to tires.
• Measuring equipment, such as pressure gauges and torque wrenches,
must be standardized and inspected at least once a year by a certified
body or, failing that, by the supplier or manufacturer.
Noncompliance with these guidelines or operating procedures can lead to
improper equipment or mounting and cause premature tire wear.
Assembly – Disassembly
Tracks with high banking in the turns impose specific tires and/or
operating conditions.
Prior to any use, consult the terms of use at michelin.com/motorsports or
contact the Michelin Race Tire Distributors or Michelin Consumer Care.
2 – RECOMMENDATIONS
Before-use checklist:
• Tire selection must correspond to vehicle equipment, as defined by the
vehicle maker and manufacturer.
• Make sure that all tires on the same axle are of the same type (brand,
commercial name or industrial reference, dimensions, structure).
Prior to mounting, make sure that:
• The diameter of the rim corresponds exactly to the inside diameter of
the tire.
• The width of the rim corresponds to that recommended by the
manufacturer or, failing that, to the standards cited (ETRTO, TRA,
JATMA, etc.).
• The rim type (tubeless, tube type) corresponds to the type of tire.
• The rim is in good condition and does not present wear-and-tear (cracks,
deformation, etc.), and the valves are in proper condition. If not, have
them replaced.
• Lubricate the tire rim seats and beads with a suitable product.
• For tube-type assemblies (with an air tube), the dimension of the air
tube must correspond to that of the tire (section and diameter), and
the rim must be in a condition that can accept the air tube without
damaging it.
Bead-Seating
• Important note: Only use bead-seating/filling installations intended for
that purpose. Under no circumstances should the operator remain in the
immediate proximity of a tire assembly. Therefore, make sure that the
compressed air hose attached to the valve is equipped with a safety clip
and that it is sufficiently long for the operator to be at a safe distance
away from the assembly.
• Remove the inside of the valve, start airflow and ensure that the tire
beads are properly centered with respect to the rim flange.
• If the tire beads are not properly centered, let the air out and start the
entire procedure over, including the lubrication step.
• The tires have not been repaired.
• Continue filling until 3.5 bars/50 psi in order to obtain a good placement
of the tire beads. For higher pressure, use a safety cage during the tire
bead-seating process.
3 – Valves
• Replace the inside of the valve and adjust it to working pressure. Replace
the cap to ensure complete sealing.
• Follow the instructions for use provided by the manufacturer
(adjustment and compatibility with the rim, type of alloys, geometry).
Balancing
• Always use a valve cap with a rubber gasket. It protects the valve
mechanism and ensures the complete sealing of the tire assembly.
• Make sure that the valve is in good condition (no ovalization, no impact
trace, etc.).
• Regularly check torque settings of screwed-in valves.
• Balancing the four tires is recommended for use on a circuit.
• The balancing machines must be standardized in accordance with
manufacturer recommendations.
• Specific attention must be given to the devices (cone/screw clamp) used
for centering the assembly on the machine.
4 – TIRE ASSEMBLY AND DISASSEMBLY
5 – TIRE REGROOVING
• Tire assembly, disassembly, bead-seating and balancing must be done
on suitable good-condition equipment entrusted with qualified and
trained personnel who would ensure, among other things:
• Regrooving changes the characteristics and performance of tires. This
procedure requires the use of appropriate equipment and tools and
compliance with instructions.
• Compliance with the manufacturer and legal rules in the selection of tires.
• Prior to any regrooving procedure, contact our Michelin Race Tire
Distributors or Michelin Consumer Care.
• Preliminary examination of the outside and inside aspects of the tire by
the installer.
• Compliance with tire assembly, disassembly, balancing and beadseating procedures.
6
• Make sure that all assembly equipment is suitable for the type of
assembly. For how to use this equipment, refer to the manufacturer’s
user guide. Comply with the direction of assembly for directional tires.
• Reminder: Regrooving or tread deepening of ECE R30 or DOT-certified
tires (i.e., those designed for use on public roads) is prohibited.
6 – STORAGE AND SHIPPING
In order to preserve the characteristics and properties of tires, important rules such as temperature
regulation must be observed.
Range
Minimum temperature of freight and storage
Slick (Track) and Asphalt (Rally)
Other Tires
0º C / 32º F
-10º C / 15º F
The following should be avoided:
• Direct and prolonged exposure to sunlight, sources of high heat (extended storage
in container) and humidity; long-term storage in stacks.
• The presence of solvents, lubricants, fuel and other chemical products.
• Equipment causing ozone emission (transformers, welding units, electric motors, etc.).
T he storage space must be dry, well-ventilated, without direct light and reserved for tires.
Racks suitable for storing tires vertically should be used to avoid exercising pressure
on the carcasses.
7 – TIRE AGING
• Tire material properties change with time, even when not used or if they are only
used occasionally; tires that have been stored improperly for long periods of time
may exhibit a loss of grip.
• Stop using tires presenting clear signs of degradation or fatigue (cracking of rubber on the outer
tread, shoulder, bead side or tire deformation, etc.). When in doubt, contact a tire professional.
8 – MONITORING AND MAINTENANCE
• Check tire pressure prior to each run and adjust pressure if it does not correspond to the
recommended working pressure. Starting tire pressure should be verified when the tires are
cold (the tires have not yet been driven, and they have not been in tire warmers).
• Inflating tires with nitrogen does not exempt you from having to check
tire pressure routinely.
• In case of unusual loss of pressure, check the outside and inside condition of the
tire as well as the condition of the wheel and valve.
• Any visible perforation, cut or deformation must be checked in-depth by a
tire professional. Never use damaged tires or tires that have run flat
without the advice of a professional.
9 – TERMS OF USE
• Never treat the rubber of the outer tread chemically.
• Never use tires with unknown pasts.
• When using tire warmers, the mounted assemblies should never be in direct contact
with the heating element and/or directly in front of the heat source — to avoid
localized overheating.
• Make sure that the pressure, camber angle, speed and axle load values are those
recommended by Michelin for the intended use (check recommendations depending on use).
Find standard terms of use at michelin.com/motorsports,
or contact our Michelin Race Tire Distributors or Michelin Consumer Care.
