Re: mileage comparison between 235/85 and 265/75 tires
I got the 235/85 16 in michelin, Right from the get go. Bought vehicle used & never drove on highway before. I turn about 2000 rpm at 70ish mph. So far the best milage is only about 13.5 (hand calculated) . I just ordered jody's chip, & hope I'll make a difference. Disapointed so far.
