Tire Conditions – Causes and Corrections

Tire Conditions – Causes and Corrections
Probable Cause:
• Tires Underinflated
• Vehicle Overloaded
Appropriate Correction:
• Confirm cold inflation pressure matches
vehicle’s recommended pressures
• Confirm load being carried is within vehicle
specifications, reduce as necessary
Probable Cause:
• Insufficient tire rotation for driving conditions
• Tires underinflated increased drag and wear
Appropriate Correction:
• Rotate tires more frequently following
vehicle’s approved patter
• Confirm cold inflation pressure match
vehicle’s recommended pressures
Probable Cause:
• Loose steering or suspension components
• Tires and wheels out of balance
Appropriate Correction:
• Replace worn struts/shocks and other
steering/suspension parts and align
• Correct balance of tires and wheels
Probable Cause:
• Tire sidewall pinched between road and wheel
• Components contaminated during manufacturing
Appropriate Correction:
• Dismount tire and inspect. Tire manufacture’s
warranty applies if no interior damage is found
• Dismount tire and inspect. Interior damage
indicates road hazard
Ozone/Weather Cracking

Bubble/Bulge
Circumferential Split/Star
Sidewall
Irregular Cupping
Tread Wear
Tread Wear
Heel and Toe Block Wear
Probable Cause:
• Wheel alignment does not match actual
driving conditions
• Worn or damaged steering/suspension parts
Appropriate Correction:
• Set alignment to most appropriate angles
• Replace worn or bent parts and align
Probable Cause:
• Frequent exposure to direct sun and hot
temperatures
• Tires exposed to ozone or harsh chemicals
Appropriate Correction:
• Evaluate service conditions and attempt to
minimize exposure to sun and heat
• Attempt to keep tires away from sources of
ozone and chemical exposure
Probable Cause:
• Impact break from road hazard or pothole
• Tire sidewall pinched between road and wheel
Appropriate Correction:
• Dismount tire and inspect for interior damage,
replace tire if damage found
• Determine if wheel is bent by inspecting for
runout, replace wheel if damage is found
Abrasion of Both Sidewalls
Sidewall
Probable Cause:
• Tires Overinflated
• Use of oversized tires
Appropriate Correction:
• Confirm cold inflation pressure matches
vehicle’s recommended pressures
• Confirm appropriate rim width and evaluate
alternative tire pressures

Tread Wear
On Both Sides
Tread Wear
Tread Wear
In Center
Probable Cause:
• Driven on when extremely low on air
• Driven on when flat
Appropriate Correction:
• Dismount and inspect tire for interior
damage, replace tire if damage is found
