2 door Jk 2015. I have an appointment to get 4.88's and a 2.5 lift installed by Clayton Offroad here in CT. Now I need to choose wheels and tires.

I'm going to run 35's 90% of my time is on the roads, some highway driving.

I'm pretty certain I'm going to choose some Nitto Terras 35x12.5

I'm in total obsession mode. My initial thought was to get some 20 inch wheels with a -24 offset, but after doing some research I'm not so sure.

I definitely want the wheels to stick out a bit, but I don't want to completely make my JK into a poser mobile. So now I'm leaning towards 18x9 but with a negative offset still.

What is the difference between a 8, 9, or 10 inch wide rim?
How will + and _ offset effect my ride?
Should I stick with 17, 18, or go with 20" Wheels?
UGH!!!! Feeling lost, but having fun.

 

IMO if you mainly going to run 35's I would stay with the 17"s because they are cheaper than the 18 or 20's and go with a 8-9" rim with a 4.5" backspacing. Your tires will stick out about 1-1.5" from the fenders but with the lift that should give you a correct stance. Just my

 

Thanks , starting to consider prices. also, don't want rocks flying up hitting my windshield.

 

Offset can be tricky. + pulls the tires into the wheelwells, - moves the tires out. How far will vary depending on the specific rim width.

As a suggestion, convert Offset to Backspace, then just subtract from 6.25

The typical recommentdation for 35x12.50's that you will find suggested by most lift mfg's, and even in the faq's stuck to the top of this modified area, is a 4.50" backspace. (6.25-4.50 = 1.75" further out than stock.) Higher backspaces can work for 35's, lower backspacing might be wanted if you think your might go to taller tires in the future.

Rim diameter is a preference. 17" will have a better selection of tires than 18" or 20", and tires should be cheaper. But if you like the larger diameters, go for it. Just pay attention to the backspacing.

Rim width is another preference. Can't say that I noticed an onroad difference between 8" and 10" when running 35's. But some will note that narrower rims will be better if you air down low offroad.

 

17" tires and 4.5" backspacing is where its at. I haven't seen many with a 10" wheel, but 8" or 9" are pretty standard.

 

Strongly recommend sticking with 17s. As a previous poster said, 17x9 with a 4.5" backspace with a 35x12.50 tire is where the money is at on a JK, it's the right compromise for track width, wheel well clearance, and tire coverage. Keeping wheel offset to a minimum also saves your wheel bearings and steering components..
