I might go with the Spec 2's. I am having a hard time dishing out more than $100 a tire considering the fact that I go through them in less than a year and I don't even drive fast or spin tire a lot. I had the 712s and they were shot after 3 months. I do beleive you get what you pay for but then again I did pay $124 each for Pilot XGT V4's that lastest less than a year.
BTW: The higher the UTQG number the faster it wears? or slower?
Would a 280 wear faster than a 340?
