    Next to the Dealership's, most auto repair shop could do the re-programming, also asked your friends, if they have a Scanner, that is capable of doing this.....also HyperTech sell a Trouble Code Reader, to Check the Service Engine Light, that also has the feature of being able to do the re-programming for a change in tire size, on the Cost, it all depends on who does it???

    I had a 2005 1500HD crew cab 4x4 lifted 6" with 35" tires 305/65/18, 4.10 gears, 5.3, 4l60e.

    I only had the truck for 10,000 before I got it repoed, and it downshifted like a mofo too. What I did to save on the transmission was speed up to help make it up the hills, but sometimes it would drop to 2nd gear and would run about 3,000 rpms to the top of the hill and then it would shift up. I personally still run larger tires on all my trucks, It's a touchy subject as many disagree.

    I should also add your cruise control won't work right either, like mike said the VSS sends pulses to the ecm. If you have cruise on say 65mph, and you hit a hill you'll get a nice surprise. My truck scared the hell out of me in cruise control, I hit a hill and next thing I know 5,000rpms out of nowhere and then it downshifted. After that I never used cruise again lol!!

    the next issue is, will this void my after market easy care warranty.... which is the reason im not lifting my truck right now to avoid voiding the warranty.

    What Year is your Vehicle, is it a 2WD or 4WD and if its a 4WD, does it have Leveling and/or Lift Kit installed on it??

    i have a 2007 new body silvy 1500 with z71 i have a 2 in RC leveling kit. 4wd. i called the local tuffy to see what they though and two mechanics there dont seem to think it will make negative difference.

    also pertaining to backspacing and bolt pattern, should i just go with my stock or since im going wider to i want a bigger off set

    IMO.....They...."the 275/70 with your....17in" Factory Rims, Will work.......I'm not a 4wd guy, so hopefully, the member's with 4wd, can either Confirm or Correct me on this.....
    :neutral:.....also its up to you, as to weather you want to stay with your Factory 17in" Rims, or go with 18in" rims, as you mentioned in a earlier post.


    Edit:.....Sorry, do you have Factory 17in" or 18in Rims??

    The Specs on both sides.....is for the Factory Rims 17in" by 7.5in in Width, with a Factory Offset of.....+31mm....which gives them a....5.5in" Backspace.
