The budget for my Cougar project has been pretty well exhausted so the 17x8 & 17x9 wheels are out of the question. I did pick up some nice second hand 15x7 wheels but they have very old tires. I need to replace them reasonably economically. All I seem to be able to find are BFG Radial TA's, which are OK probably won't give the grip that my Coilover suspension can handle. Any suggestions?
