[DeTomaso] Rim Offsets

[Gray Gregory]

Micheal,

I drove Mike Drew's Pantera on the track at the Fun Rally one year. It had BF Goodrich TA's on it and they were w/o a doubt the worst tires I've ever experienced on a high performance car! No grip, sidewalls moved all over the place with no consistency or predictability, so definitely take it easy on the way to car shows when running on those tires!

Dan,

My "big tires" are currently Pzeros and were Michelin Pilot Sports on those wheels (spokes), my other big set (Hall wheels) are Kumho's, all 17" are speed rated, the "normal 15" tires are....one set (single slots) are BF Goodrich Radial T A's and the same on the double slots ( both sets are 7/8's).

Nice catch, I'm sure they are not as highly rated, not near me to check the sidewalls.
