Bought the truck used with 33x12.5x20's on it. I noticed it has trouble staying above 70 on the hwy without downshifting (5.7L, 8-spd tranny). Other than that, it runs and shifts just fine. Roughly 75K miles on it now. I do mostly city driving with the occasional few-hour hwy trip, and Its never towed anything yet, but I'll be eventually towing my wife's altima (military move). You guys recommend I get the gears changed out for this tire size increase before towing something significant? I plan on keeping it for years to come. Thanks!
