I bought my MR2 about 20k miles ago and when I bought it, the tread on all 4 tires seemed to be ok. However, last time I had it up on a lift I decided to take a look underneath for a bit and noticed my rear right tire is almost totally bald, while the other 3 have probably 60-70% tread left on them. When I took it to my mechanic, he said the Spyders are known for that; he said the torque of the engine doesn't turn both wheels evenly...anyone else have that issue? Would that be an alignment issue? I doubt it would considering it's only happening to one tire.
when I bought my spyder I had a mildly similar issue, but it also tracked funny, I had to hold the wheel to the left while traveling in a str8 line... turns out that the toe alignment was off on bot rear tires, one + and the other -... caused my car to litterally travel like this | / |going down the road... if your expirencing something even remotely similar, aka having to hold the wheel to the left or right, you def have an alignment issue...
do NOT go to Sears, they can't ever get it right and will tell you that pulling to the right is recommended from the factory... BS!
I went to Brakes Plus and got all 4 aligned for about $60, and you should get it done every time you put on new tires..... just food for thought...
currently, I'm fighting a camber issue, but 3 of the struts on mine are shot.... saving money for a 32 way adjustable full suspension....
