I've had several sets of T/A radials. I don't recall them being very "smoky" tires. The 275's I had on my old '70 challenger hooked so good that my buddy with an mid 11 second 440 Dart refused to run me from a dig, and mine only did low 12's. I don't know if the tire compound has changed from back in the 80's or not. I had the batt in the trunk, a pinion snubber, springs clamps, an air shock on the right side & 30lbs of air in the tires. They worked
really good when they were about 1/2 worn out.
