Need Help With Wheels & Tire size

[Gladiator gator]

I am new to the forum as well as a new Gladiator Rubicon Jeep owner. I am looking for feedback regarding if the wheel and tire selection I am looking to purchase will fit properly. I am currently looking to put 20"x10" method rims with a 37" x 13.5" Toyo RT on my Rubicon. I will also be installing the 2" mopar lift. Does anyone think I would have any clearance or ride issues with this set up? Your feedback is greatly appreciated.

Despite my aversion to 20 in rims on a Jeep I can try and help you out here.

Honestly 20s are terrible in every way possible. They weight a ton causing more unnecessary rotational mass. You can't air them down as much and the side wall flex which directly equates to ride quality both on and off road is deminished.

That being said.

The crucial piece you are missing is back spacing aka offset. You will probably need 5in or 0offset for that combo.

Thank you for your reply, Greatly appreciated. I will be using this as a daily driver, Will probably never see a trail Do you think I would need the 5" offset with a 37"x12.5" tire?

For a 12.5 tire you can get away with more positive offset. AEV specs their wheel at 5.7in of backspacing and that puts a 12.5 just barely inside the fender. 5in puts a 12.5 at about half an inch of tread past the fender lip.
