I used to run a 275/50 Radial TA on my 5-speed mustang that ran 12.30s on slicks. I made LOTS of passes on the radial TAs. I would roll through the water(not much choice) and do a quick hard 2nd gear burnout. Worked well it ran 12.30s on slicks and 12.70s on the radial TAs with a best 60ft of 1.83 and consistant high 1.8 60s.

If you go drag radials stay away from the Nittos. I found they worked very well on the street but not so good on the track. They also were pretty scary in the rain!

EDIT, I was running these tires on an 8 inch rim and ran pretty low pressure. If I remember it was 18-20psi. I would also rotate them from side to side when the tread started to get sharp. The track was open 3 times a week and I was always there, no telling how many passes I had made on those tires.
