Uneven Tire Tread Wear? - Toyota Yaris Forums

turblown · 07-09-2017, 11:20 PM

All four tires have uneven tire wear in the center of the tread. Currently the tires are measuring approximately 4/32" on the inner/outer tread and 3/32" on the center tread. I know this is normally caused by over inflation, but they are at the recommended pressure of 32psi.

What could cause this type of uneven tire tread wear?

Should a different tire pressure be used due to going with larger than stock tires and rims? Do tires tend to wear unevenly towards the end of life? Is it possible that these are just crappy tires? Is there a mechanical failure that would cause this?
