My right rear tire is bald and my left rear tire still has a couple thousand miles left. I've also only gotten about 8k miles out of them (Fuzion ZRi). I had an alignment done and I was told that nothing looked wrong with the car.

 

i have a similiar problem w/ my rear tires aswell....

except its my rear driver side tire thats showing really bad camber. my car is lowered on neuspeed springs. The inner most thread is bald while the passenger side is balding but not as quickly as the driver side. i did the alignment when i put the wheels on about 12km ago...

i dont know what has caused the uneven tire wear.... my only guess is uneven tire pressure?
