Should have had them send a different set when you saw the 99.5. the only tires I ever purchased for my race cars that were spot on were Mickey PBR's.

I feel for you. This happened to me back around 92 with a set of Goodyear's. Always ran 31x13 and never had a clearance issue, until I did. They measured out closer to 32". Now I always check the circumference before mounting. I hope Hoosier steps up for you. Good luck.
