another tire question

[flips72]

i finally got to take my truck to the strip last night and the old girl done allright considering i was onn street tires, 7,82 at 85.69 mph, now ineed some traction, anybody know whats the best tire combo, drag radials for a stock suspension 65 with factory tubs? right now i am running a 255/70/17 toyo proxy all the way around but it was blowing the tires off. i will probably go back to 15 inch wheels because i want to run at least a 29 inch tall tire and theres not anything in the 17 range, or at least that i can find. thanks for the help.
