I just got off the phone with a guy at a 4 wheel drive shop. He told me to go ahead and throw 265 or 275 70 16 on it and let em roll. And not to worry about the computer stuff because that would only affect the MPH a few miles an hour. As far as the warranty goes he told me to keep the old tires and if something happend to any part of the truck throw the old ones back on and take it to the dealer. That way they would have no clue that bigger tires were being ran on the truck since the computer was not messed with and they would not be able to void my warranty that way. Im thinking I will just take that advice and hope for the best.
Im thinking 275/70/16

The picture is me yanking out a GMC that was stuck in sand. (The tow strap is hard to see since the picture is so small)

Nice picture. Too bad we can make out the driver.

I wish I knew how to make the picture bigger.

I got a 2002 F-150 4x4 with Mickey Thompson 305/65/17 and have plenty of room with no rub.
