GET RID OF THE BIAS PLYS....I prefer the BFG Radial TA's over Cooper Cobras, I tried the Coopers on my old Dakota R/T, they didn't last very long or wear very well, but that's just my personal experiences/preferences, not any scientific study or good examples, the same size BFG TA's seemed like the had better braking, lasted a bit longer & seemed to handle slightly better... Unfortunately BFG doesn't make the Radial TA's in P295/50/15 sizes any longer & IMHFO the P275/60/15's aren't wide enough for my taste, on the rear of my RR or any late 60's B-Body {I have a like new pair of the P275/60/15 BFG's sitting in my shed}, I like the wider tire & stance much better... they also make a decent Comp TA's for superior handling too, good for dry conditions, but they don't last too long regular driving, better compounds, but maybe 1/3rd-1/2 the life of Regular BFG Radial TA's, I had them on my 1994 25th Annv. SLP Trans Am, they were hand down "way better", than the original Good Years GT's that came on the car... I may end up swapping to different size/diameter & brand/style of rims & tires, when my current tires are worn out on my 68 RR... There is allot of great tire technology out there today, unfortunately the 15" tires selection & available sizes, I don't like anything bigger than a 17" rim diameter & the 15"ers will be a thing of the past, pretty soon I fear... When I find something that works well, I stick with it, I've had BFG Radial TA's since the mid seventies, on most all my street cars, I've never had any issues, it's kind of Brand Loyalty I guess or maybe me being stubborn as hell & not willing to except change in my life...LOL... When I go to the track, I either use BFG G-Force T/A Drag Radials 325/50/R15 or some older M/T Drag Radials that can be street driven too, but won't last very long, but they do handle/corner slightly better than the BFG G-Force Drag Radials thou....
