I have a tire issue that nobody seems to be able to figure out. I have 19's with about 4k miles on them, but all 4 tires are cupping on the inside and out but are wearing evenly. Stock susp, recently aligned, tire press is correct. I went to lexus and 2 other tire places and all I got was a confused look. Oh yeah it's a 2000. 245f , 275r Any help would be great, thanks.

 

suspension setup?
make sure that the toe is set right.

 

toe, explain more please.

 

watch this video, discusses vehicles suspension. http://www.youtube.com/watch?v=_D_vg8gnMms

 

I see, everyone who looked said that all 4 tires were wearing evenly. they pretty much told me that it was a bad set of tires. And to make things worse no tire brand will warranty cupping.

 

The susp setup is the factory air, I even had it checked out for leaks. The car only has 54k miles. My friend is a service tech at toyota so he put up on the rack and checked all the bushings, swaybars pretty much everything. Conclusion was crappy tires. I'll bring it back and make sure the toe is where it should be. Thanks for the input.

 

You might want to double check your air. Tire cupping is caused by lots of bouncing and tire movement on the road due to a bad shock or lack of rotation.

 

yup, check your alignment again, and verify the air suspension is functioning properly.

 

Cupping on all 4 tires, inside and out with even tire wear? I've never heard of a suspension problem or tire inflation that can do that.
I vote for crappy tires.
