They still sell BFG RAdial TAs in many sizes for one reason; they are VERY popular as most of us think there's not better 'era relevant' tire to run on a muscle car..

I like the look of the Goodrich radial T/A but don't agree that it is correct for the era. As I recall there were a lot of Firestone and Goodyear tires around in 1968. I think that the Goodrich T/A's became popular a little later.

Mike is right... in the late '60's and early '70's no one was running radial tires on a muscle car, because they really weren't available, or at least not available in the low profile sizes for muscle car.. If radial tires were available at all, they were being used on luxury cars - and I really can not recall when they became available on luxury cars, but it was the mid-70's probably before the Radial TA BFG became the 'popular car' on muscle cars, just as the 60's muscle cars were becoming in vogue. When I said 'era relevant', the era I was speaking of was mid-70's forward... and I still don't know of a radial lower profile RWL tire that looks better on our cars than the BFG Radial TA..
Thanks Mike for correcting the thought I may have created inadvertently. In the late sixties and early 70's, the tires being sold on and for our cars were all bias belted tires... Firestone Wide Ovals, Goodyear, etc... My wife's '70 Mach I came with F70-14 Firestone Wide Ovals; most muscle cars came with F70-14 or F70-15 bias belted tires when new and were generally replaced with those type tires the first times they needed tires. I ordered a '70 RR in late '69 and ordered it with F60-15 Polyglas GT tires, and my car was the only car around my area with even those tires at the time; I think it was 1973 before the new Corvettes were delivered with radial tires...
