16in 255-50-16 bfg drag's or 15in 275-50-15. I would favor on getting the 15's for the strip.The extra sidewall of the 15 will help at the line.You can get a used set of 15in rims from ask frank first in saddle river nj (next to e-town) for next to nothing to mount them on or you can always mount them on the rims you have now.
