Hi nice truck, checking gear ratio. Block the front tires, jack the rear up put the trans in neutral and mark the drive shaft and then turn the rear wheel one turn and count how many times the drive shaft turned your truck should be 4 turns and a very small bit, as it should have 4.10 gears stock. I am not sure if the dealer can put any size tire in they may be limited, ask them. Hand held programers you can change tire size like superchips or diablosport i have had both.

Well I'm going to ask for a programmer for xmas . I basically need to adjust my speedometer, but won't mind other added perks. Anyone have any suggestions on which programmer to get? I have a 2005.

Hi i have a superchips cortex and predator diablo sport for my 2008 h2. I am using the predator because their was a few problems with the cortex and my truck and superchips customer service sucks IMO from dealing with them. My truck didn't have any problems before i installed their program. They said the problems i had were in my truck but as soon as i unstalled their program my truck was fixed. Also when i installed the predator program it works fine. Maybe other guys have had better luck with superchips but i will never buy from them again. I have a $400 paper weight. Hope this helps.

I used the Hypertech Power Programmer and it has never let me down in my previous vehicles.
