Just did a trial fit with a set i had left from the nova. Put them on my 8" wide pro stars about 3/8" clearence between sidewall and frame and the same to the fender lip that is rolled, at full compression. How much will these grow during burnout and a run. I noticed under compression tread area of slick is 1/2" from inner fender seam at back of wheel well. Not Sure if i would be better off with 28". Any suggestions or thoughts.
