Ok, there is something wrong with my car. I already went through 4 tires with 35,000 miles. I had 20" rims for about 6 months before my rear tires went completely bald. So I put my stock 17's back on and 2 months later, these are now bald. I also have eibach springs. Do you think it's lowering the car that makes the tires run out so fast? I also do a lot of freeway driving everyday, going about 60-80mph.

I'm assuming you went through 4 SETS of tires in 35k? Lowered cars generally have greater camber so will eat up the inside of the tread faster than normal. Is this what you are experiencing?

 

yeah, my tread is all gone in the middle, but the outside has plenty of tread. How come lowering the car causes camber? Shouldn't the wheels be in the same position, but the car just lowered?

 

Sounds like overinflation. What psi are you running?
