tire size on stock 15x7 wheel
 

whats the widest tire i can put on 15x7 ford turbine wheel on a stock 90 GT? i think 91+ have the larger fender clearance so thats a negative for me. can 245/60SR15 fit up front and turn lock to lock w/o rubbing?

for the rear how big can i go on those stock wheels? can 275/50SR15 fit if i turn the quad shocks upside down? seems like a lot for a 15x7 wheel though. maybe 255/60SR15 ???

My '89 GT has stock rims with 225/50/15(F) and 245/50/15(R), the rears are alittle big for the back sides stick out just a hair.

I ran a 275/50 drag radial on 15x7's, but they buldged out quite a bit and just didn't look right. A 255/55 is a good fit though.
