If you fitted tires other than the OEM size or fitted non OEM wheels, post the fitment results here and include the following information:
Tires Size; Tire Brand/model; Wheel brand/model; Wheel offset/backspace/width; Lift size or QL; Wheel Spacer; Rub/No Rub; Modifications, Spare well fit. Add any install notes and advice. A photo if you have one. If you are fitting non OEM wheels, mention if you have HD or STD brakes. Also mention if you've driven in mild or challenging off road conditions.
We will update the fitment summary tables below as reports come in.
All other posts will be deleted but feel free to discuss and ask questions in other tire/wheel threads. Ask questions here too, but every once in awhile we'll go through and clean up the thread, so don't be upset that your post gets removed.
In general tires less than 32.1 inch can be made to fit without modification. Common "easy" mods to fit larger tires are folding over the pinch weld (see the modification sticky thread for instructions), removing the front fender air dam, trimming the felt fender liner and screwing it down tight, and using wheel spacers. Adding a lift or leveling kit is more difficult but WK2 spacer or spring lift kits are not changing the suspension articulation, just the steady state resting point. If a tire/wheel is too large, lifted, stock, QL or not it will rub the same when at suspension limits. Since QL has a lowered park mode, it will take much less of a bump to hit the suspension limit than a lifted Jeep, but both will eventually rub with the same tire and wheel combination. So a lifted Jeep will seem to give you more tire clearance on a bumpy road and everyday driving because there is more travel before rub (i.e. more margin). When you are worried about tire rub under any condition, which WK2 suspension you have does not make that much difference. If you are only worried about no rub most of the time, in theory you may be able to squeeze a bit more tire in. As far as we know, currently there are no lift kits available to the public that modify control arms or suspension articulation, as there are for some other Jeep models.
OEM wheels have a 56mm offset. A nice tire/wheel size comparison tool is here: http://www.rimsntires.com/specs.jsp Many reports do not mention HD or STD brakes, so beware of using 17s with HD brakes. If you are going custom wheels, a 18mm offset seems to be the sweet spot for maximum clearance.
Summits have wider fender trim. Note that the Summit trim on later models is wider than other models. There is less tire clearance.
The dark gray boxes in the table below highlight Stock sizes. Note that the dimensions in this table are tire standards, there is wide variety between brands and models, so always check the manufacture's spec sheet. For example; 275/65R18's on OEM rims seems to often fit without any mods, but others report rubbing. Not all 275/65R18s are the same size, Nittos have a tendency to run small and fit well where other brands run larger and rub.
Tire/Wheel Fitment Summary; Updated January 24, 2015
Michelin ltx ms2. 275/55R20 on 20" gloss black Overland wheels (same dimensions as stock 20's). 1.25" Bora spacers. Had an occasional rub on dips at high speed and off road. No rubbing at all with the RRO Leveling Kit, with or without spacers.
Those Rims do look awesome. Would you mind posting a side shot so i can see the offset next to the fender flares. i was thinking about picking up a set of these for my 2011 and powder coating them black first. maybe 2 tone. Great looking ride.
I also was going to power coat them black but linking the colour now... Here is a shot of the tire front the front and rear on a cold morning.. You can see the tires don't really stick out at all.
I do get a little rub when in park mode and fully turn the wheel it makes slight slight contact with the inner fenders. Noticed it while backing up the trailer last night.

Daily - 2011 Grand Cherokee Overland v8
I'm running 20x9 Fuel Maverick wheels with + 20mm offset. Tires are 275/55/20 Nitto Terra Grapplers, about 32" diameter. No rubbing unless in park mode with the steering wheel cranked all the way to one side. It will go lock to lock in standard height mode without rubbing, which leads me to believe the set up will work on non-air suspension models. Road noise is slightly higher than stock, but it's a barely noticeable difference. The noise is reduced on some road surfaces. I've noticed a loss of about 2-3 mpg according to the EVIC, but that was also at the same time I reinstalled the roof rack. Mileage may go up after I remove the basket, we'll see. I'm not too worried about it.
I put the Eibach All Terrain Lift on my 2013 WK2 Laredo (2" in front, 1/2" in the rear), got some new wheels 17" x 8.5" 5-127.00 (1/2" wider and slight offset from stock wheels), and wanted to go up one size from the stock tire (from 245/70-17 to 255/70-17), but the larger tires were very close to the wheel well and would have rubbed when the suspension compressed, so I stuck with the stock tire size.
2014 WK2 with QL
Tires Size: 255/75/17
Tire Brand: Duratrac
Wheel brand/model: Rubicon Wheels
Wheel offset/backspace/width: none
Lift size or QL: QL (Works fine in all OR and Park modes but really reeally really close on the park mode.)
Wheel Spacer: None
Rub/No Rub: No Rub
No Rub in all modes (but I wouldn't drive in QL Park mode as its REALLLLY close)
Factory Overland wheels with Cooper AT3s 265 65 18. Perfect fit, and spare fits in with the plastic buckets intact.
2014 Overland Oiler, ORII, QD, Granite/Indigo Blue, rock rails, Cooper AT3's - oh yeah!! Officer, these handcuffs are tight!
Just relax, they're new. They'll stretch after you wear them a while....
I swapped out the factory tires when I took delivery. Had them put on 275-65/18 Goodyear Wrangler Adventure Kevlar on the factory wheels. Have QL and zero rubs even with the suspension in the down position. I really like these tires on the street, very grippy in the wet and not at all noisy. I haven't gotten any miles yet on trails.
