I was a BFG fan for years and years. I usually ran 235/60/15 front and 275/60/15 rear BFG T/As. A couple years ago it was time for new tires on one of my other cars, and I found that the BFGs ere backordered so I read the reviews on tire rack and then tried the same size Firestone Firehawk Indy 500s. I found that the Firestones gave me much better cornering traction - both wet and dry.
Besides handling better, I found that it took alot more to break the Firestones loose.
On my 70, I put on a set of 245/60/15 front and 275/60/15 rear Cooper Cobra GTs because I got a great deal on them. Surprisingly, I also like these tires better than the BFG T/A.
After 2000 miles on the Coopers I still think the Firestones have better traction and slightly less sidewall flex. When it is time to get new tires again I plan on going back to the Firestone Firehawk Indy 500s.
