I think I really want to buy some 17-18" wheels and some slightly more off-road oriented tires (I will spend 95% of time on road, so I appreciate something quiet and that wears well). I checked tires.com and tirerack.com, and they don't list many wheel options for this model. Does 2013 GC come with a funky bolt pattern or something?.
Not a funky bolt pattern but the offset is large, front wheel drive territory.

If you have HD brakes, 17s will not clear the caliber.

There is a parts for sale section of the forum classified section.

Just to confirm...i have a 2013 overland with oem 20" wheels.

Will a 275/55R20 fit without rubbing anything at all the QL heights?

What about a 275/60R20?

Will these wheels fit over WK2 hemi brakes??

http://www.boldride.com/ride/2013/je...cept#gallery/2

I love the look and stance of this concept for the 14' Trailhawk and these are the wheels that came on the new 13' Rubis, will these wheels fit my hemi wk2 Altitude Edition? i've checked out the wheel sticky but found nobody that has ran these wheels yet, thanks for the input and help guys.

275/55/20 should work. That is a 31.9" tire. I have a 32.1" tire on my QL Hemi. Please see post #185 for details on this size.

I really doubt 275/60/20 will fit as that is a 33" tire.

Help!

I've been through the search function and both wheel and tire threads and have found numerous mentions of speedo inaccuracy after moving to bigger tires. I can't seem to find anybody who has a solid answer to whether or not anybody can recalibrate speedos to accommodate larger tires without using a tuner. Am I missing something obvious or is the only way to recalibrate the speedo to go out and buy a tuner?

Dealer can reprogram the computer. I did last year although I have no way to really tell if they did.

Jackal,

Thanks! Wasn't sure if I had missed something. The best way to double check would be to use a dash-mounted GPS. Most will display your speed using the time it takes you to travel a certain distance based on your GPS coordinates, so it's not biased by wheel size. Set your cruise to 60, give the GPS a minute to catch up, and see if it reflects that you're traveling 60 mph. You want to stay at speed as long as possible to insure the GPS gets a good signal and read (They normally update every second or so). It's a quick and easy way to make sure your speedo is accurate. If you don't own a GPS see if you can borrow somebody's. 70 or 80 would be a better speed to use (because speedo inaccuracies will be exaggerated at higher speeds) but some folks don't have roads on which they can drive that fast.

If they are 17", no. I've read only 18"+ will fit. Those look like 17s?

I did that the day I did it. I even downloaded a couple speedo/GPS apps along with my GPS AND even drove by one of the automated speedo signs by LE on the side of the road. All the readings were 1 or 2 off the Jeep speedo.

This is the first I've read where any dealer can reprogram for differant sized tires on a GC.

That must have bee a recent change to their software. The tire factor menu item used to not even be presented for the WK2, as they wouldn't need to change it anyway (all the OEMs have the same tire diameter regardless of wheel size). Other chrysler vehicles can be programed by picking a tire factor from a menu, but the only factors presented to the tech are those for OEM sizes. Nothing aftermarket. On my 2006 RAM I just got used to adjusting 5%.

Running oversize tires on the WK2 is not an approved Jeep mod or an offered accessory.

Although I do not trust the dealership with much when I asked them to reprogram the computer for my larger tires they said they could and did. Now, post larger tires and before the reprogram my speedo displayed speeds very rapidly ie: traveling 40 mph the EVIC would "flicker" 40-41-39 etc very quickly. After the reprogram the the EVIC/speedo worked as normal. Not sure what was really performed since the invoice only said "customer requested reprogram of computer for larger tires" and charged me $60. I think they did however I cannot know that 100% since I cannot see the computer specs obviously. And this was a year ago I did this.

Did you try checking your speed against a GPS?
