Drag tire question.

I’m trying to decide on new wheels and tires for my 70 duster. I really like the look of the 17-18” rear tires over the 15”

I wanted to go with the Mickey Thompson Street ET Street R radial tires. I am finding out from articles and friends that the 15” with the bigger sidewall has more traction. The car will probably run in the 10.80-11.30 range. Does anyone have any experience with the 17” tires. Wondering how much of a traction difference there is.
It's hard to get the "look"and the traction. Pick one or the other
