    I'm running 275/55/20 tires, on 20/8.5in" Factory Alloy Rims, the tires have a Section Width 10.8in"s, same as the 275/70/18's.....and I've had no Issues or Problems with this setup.

    I would also mention.......if you Install a Larger Overall Diameter Tire, then what you have on your Truck Now......Keep in Mind, your Trucks Computer Calculates your Trucks Speed based on the Diameter of the Stock Tires. by installing Taller or Shorter Tires, the Trucks Computer doesn’t know how Fast the Truck is going. As a Result, the Automatic Transmission may Not Shift Correctly and the Speedometer Readings will Not be Accurate(as required by law)......and You Should and/or Need to have your Trucks Computer reprogrammed for this Change in Tire(Overall Diameter)Size.

    damn that is really helpful. thanks i appreciate it. see and im not much of a car minded person so i wouldnt really think that adding an inch would change my speed almost 3mph. im assuming that can do some major damage to a tranny.

    where would you recommend i go to get it re-programmed? a dealership? also any idea ballpark the cost on that?

    The speedometer wouldn't really bug me that bad, BUT Mike's right about the shift points. You will know if it starts up and down shifting going up hills more then it used to, to me 33" tires are borderline depending on your gear ratio. Congrats on your choice, they look real nice!!

    You'll get a long time out of the tranny depending how you drive, my boyfriend had 33"s on his Colorado and he ran it with 3.42 gears and a 5 cylinder. It constantly downshifted, and was annoying as hell but he kept driving it. The 4l60e held up fine, but after about 50,000 miles of this the 3 and 4 clutches finally wore out and were in need of replacement.
