I think I figured out why the tires are different sizes... The guy I bought the car from was a cheap I&!*t.

On the side of each Bridgestone tire is a number stamped during manufacture. While the fronts match each other, the rears do not. Also 3 of the tires have cracking from age... (2005 with 36K on it...) The bigger one in the rear does not have any of these cracks.

Conclusion: He replaced one back tire at some point and made the problem himself! Way to save a couple of hundred bucks...

Thanks for everyones input.

Yup. I'd still get the alignment checked. If he cheaped out on tires he probably never got it aligned.

 

Yeah man... Will be getting a performance alignment with my g-force rivals. Next AutoX is going to be fun.
