Randy keep in mind running on a stock 17" wheel doesn't make my truck any slower on the street, just faster on the track. Frankly, more than half the time I run on my stock 17's anyway. The truck drives better in every way. It rides better, it stops better, and it feels lighter. I prefer it. If it was my truck, I would have grabbed some really nice looking 18's with a sporty tire, but to each their own. Eventually I'll do the same, but a set up that is made to look "racey" doesn't have the same appeal on a Denali IMO.
I respect what your'e doing for sure!
Also, lets not forget
