If you’ve just installed a set of bigger tires on your stock wheels or on a set of new wheels with too much back spacing, there’s a good chance that you’ll have some rubbing issues on your front sway bar, frame rail and/or lower control arms while making a full turn.
If you want to run bigger and wider tires on your Jeep JK Wrangler, you really need to do one of two things. One, buy a set of new wheels with less back spacing or two, install a set of high quality wheel spacers which will effectively reduce the 6.25″ of back spacing that your factory wheels have.
Unlike previous Jeep Wranglers that had a simple gear in the transfer case that you could change out with ease, the all new JK Wrangler is completely computer controlled now and calibrating it’s speedometer and odometer to match any tire taller than 32" or a gear ratio any higher than 4.10 was virtually impossible. That is, at least until now anyway.
Thanks to the guys over at 4 Wheel Drive Hardware who just sent me the Pro Comp ACCU PRO, I was able to accurately calibrate both the speedometer and odometer on my Jeep JK Wrangler that is currently running 315/70R17’s (approximately a 35×12.50) Pro Comp Xtreme M/T’s and Superior 5.13 gears. And, if I had an automatic, the ACCU PRO would have also instantly corrected the computer controlled shift points as well. |
So, how have the Pro Comp Xtreme Mud Terrains been performing? Well, I can tell you that since I got them about a month ago, I have racked up about 3,000 miles on the odometer with a good 1,500 miles of that being put on driving out to Moab, Utah and wheeling the hell of the them there. And, I’d have to say that I’m pleasantly surprised as to how much I really like these tires!
I did an install on the Hutchinson beadlocks and wanted to give you a look at them. The first thing you notice when you pick one of these wheels is the weight–55 pounds each. The quality of the wheel is impeccable. You can tell they are produced by a company that builds for the military because these wheels look like they could stop a 50 caliber round.
