rear left tire problem

I'd rec getting the alignment checked poss problem with the rear axle being out of alignment or you may need to rotate the tires more

You may have a problem that i am finding on my XB. I changed all four tires with new rims as well and when the shop went to align my tires, the back left toe showed that it was off. Tiore kingdom told me they could replace the camber for me but guess what, their is no camber on the back axle, the piece is solid. I had a friend research with Toyota and he found out that their are many Scions that the axle had to be replaced by the dealer. When the cars were shipped into the U.S, the strap that they used to secure the vehicles bent the axle's of the XB's. Go figure, no wonder our left tires are wearing quicker. I have over 50,000 miles now and I have to see how I can fight my warranty. Give them hell on your end. My number is 4073509681 if anyone has a solution.

Rotate your tires
