Marginal wear
Insufficient pressure (wears out on both sides)
Underinflation causes the tire to overheat because the cord will bend too much and the tread will not sit properly on the road surface. This will cause loss of traction and excessive wear, not to mention the risk of sudden tire failure due to rising temperatures. Check and adjust pressures.
Incorrect wheel alignment (wears out on one side)
Repair or replace suspension parts.
Difficult movement on a turn
Slow down!
Central wear
Pumping
Overinflation causes rapid wear of the center of the tire tread, as well as reduced road grip, a harsher ride, and an increased risk of tire failure.
Check and adjust the pressure. If you occasionally need to inflate your vehicle's tires to higher pressures than specified for the maximum load rating or high speed supported, be sure to reduce the pressures back to normal afterward.
Uneven wear
Front tires may wear unevenly due to wheel misalignment. Most service stations can check and adjust the wheel alignment for moderate loads.
Incorrect camber or kingpin caster
Repair or replace suspension parts.
Faulty suspension
Repair or replace suspension parts.
The wheels are unbalanced
Balance the tires.
Incorrect alignment
Adjust the front wheel alignment.
