I've been searching around but everyone is either running some sort of lift or using the stock wheels. I know I am crazy, but here goes anyway:

This video is telling me 33 x 12.5 tire will fit without any lift or level.
They are using a 0 offset wheel and 33 x 12.5 Nitto Mud Grapplers.
I would like to run a +12 offset wheel with 34 x 12.5 BFG KO2s.
Would the greater offset give me the room for the 34s? They are saying 35" KO2s will fit with a +34 offset.
According to their websites the Grapplers measure 32.95 x 12.68, the 34" KO2s 33.5 x 13 and the 35" KO2 34.5 x 13.
I know I am splitting hairs here, but can anyone speak to the feasibility of fitting the 34s in there with no lift or level?

Thanks.

 

My opinion is no. I just put 34x11.5 with a +1 offset on and had to massage more than I wanted along with the level.

 

How much level?

 

33x12.5x18 here at +18 and was pretty comfy at stock height.

 

i ran 34s on my 2015 with no level for a while... no issues or rubbing

 

I put on eibach 2.0 pro truck coilovers and shocks.
Eibach told me it would be 3” raise in front but I’m not 100% positive as I didn’t measure, I also added a 2” block instead of the 1.25” factory in the rear

 

You should be ok with 34" x 11.5" tires with the factory wheels but once you start pushing the offset out with aftermarket wheels, you are likely going to run into problems.

 

Still waiting on my truck, but I’m looking at 285/65R20 on stock wheels with a 2” level. These work out to 34.6” x 11.2” wide - only 1/2 wider than the 10.8” width on factory 275/60R20s.

I would count on a level being necessary.

I’ve had experience lifting Wranglers and off-roading, and I recommend narrower tires unless you plan serious off-roading - tracking will be sketchy and the rolling resistance will hurt mileage and performance.

 

295/60/20 stock height

 

I ran 285/65/20 Nitto Ridge Grapplers on my Stock 22 Platinum wheels for over a month with plenty of clearance all the way around and I didn't just drive on the highway either.
