Hey guys.
I suggest jacking up the car in the front enough to get the tire lifted off the ground. Place your hands at the 3pm and 9pm positions at the tire and look at the rear bushing on the lower control arm. Try to move the tire with your hands left and right using your body, if the control arm moves back and forth you need new bushings. What happens is when the car moves the toe moves and eats the inside of the tires. The stock rubber bushings I have found to suck and don't do the trick.....I ate a set of tires quickly for me.
whiteline makes a good set of poly bushings which are solid, none of the crappy rubber bushings that you can still move when new. I honestly have no affiliation with whiteline, just annoyed with my problem of eating tires and want to ensure others know about the options. if you are eating the inside away of your tires its probably a bushing issue......change them and don't look back.
