Also, what about braking. Did you lose a lot of stopping distance?
Thanks in advance!
Fixed it for ya bud
.................it really depends on how/where you drive your truck.........if you do alot of city driving then yes you will notice a decrease in MPG, as to how much, again depends on your right foot cuz the engine does have to work harder to turn those 37's. If you do alot of highway driving your actually getting more distance per revolution because your tires are bigger, so your MPG could go up if its not too hilly. With the truck being a turbo downshifting shouldn't really be an issue as the turbo boost will make up for the power needed but again this will bring down your MPG
Gears really don't affect your stopping distance, but as for the tires, yes they will, remember your adding a bunch for rolling mass with 37's, its just simple physics.......but its nothing the truck can't handle
