Mileage with 325/60/20's??
I have a 2011 crew/long black on black, with black Rock Star's, & Goodyear Dura Trac 325/60/20's.
What are guys doing for mileage on yours. With my stock 18's I was at 19.5-20.5. I went to the 325's and it droped to about 15-15.5 average. I am running a Bully Dog tune. Wondering if I should pull my programer & see what my mileage does or if I should try a differant tuner, maybe h&s??
If I could figure out how to post a picture on here, I would.
