Gladiator Sport S on 35's, Mopar 2" lift, `96 XJ, 97 ZJ, `99 Camaro LS1
It’s fixed, they didn’t recalibrate my steering after the lift. Only re-centered the steering wheel.
Well this is a new one to me. When you say "recalibrate" do you mean an actual alignment in addition to centering steering wheel? Does anyone else have info on this? I do my own work(the mechanical end anyways) but all this extra techy stuff is new to me.

So, the gladiators, and I believe newer wranglers, have an electro hydraulic power steering system. So kind of a hybrid of true electric and hydraulic.
Service guy told me he recalibrated my steering system through the computer. I have minimal mechanical abilities so I can’t really explain any further than what he told me

How does the 37 13.50 drive ? I have the 37 13.50 cooper sst pro on my Rubicon and it pulls to the right and we have done everything to stop it. swapped and rotated all the tires around and even bought the lower adjustable control arms and it stills pulls to the right,. people are telling me its the wide 13.50 tire that rides outside the crown on the highway. I had the ride grapplers in the 37 12.50 and it drove so straight but it started pulling when I put the cooper sst 13.50 on it. so does yours drive real straight ?

These pictures were found on FB And the Jeep is at Westgate Jeep in Raleigh NC for 66k. It is 37 inch tires and a lift. I’m assuming Mopar since dealership added it.

Are these 37 12.50 tires or the 13.50 ? I have the 13.50s and can't stop the pull. it drove straight before on 12.50s but everyone tells me its because of the 13.50s ride on the outside of the crown on the hwy and it pulls. yal like the wider look of the 37 13.50 or the narrow 37 12.50 better ?

They have it figured out for sure and they are available already for the JL which SHOULD be the same as the JT. The only question is will they fit the JT and that is because of clearances with stick on wheel weights and the brake caliper. I don't know if there is any differences in the brakes on the JT vs JL and there could be as the tow rating may require larger rotors and calipers than the JL requires. On the JL they fit fine but you can only use 1/4oz stick on balancing weights or else they'll hit the calipers.

But ultimately, there is no "proper" wheel for a 35 on the JT, it all boils down to personal preference..

Pretty sure those are 37's below..

Good idea to look at Mopar's wheel offerings! Might be a typo, but wouldn't an 8.0" wheel width with a +12mm offset create 4.472" backspacing? (4" from center + 12mm which is 0.472")

In my opinion Mopar's backspacing on their JL/JT wheels is a good rule of thumb when shopping for wheels. Doing so should ensure that everything operates without obstruction on the back side. It also is likely just enough space for 35" (and maybe 37") tires to fully turn without rub...and without that super wide wheelbase look.

Here's a table that gives the offset required to match Mopar's backspacing for various wheel widths.

Every -25.4mm of offset pushes the tire 1" out from under the fender flares.
Wider wheels (while maintaining the same backspacing) will also push the outer edge of the wheel out from under the fender flares.

Extending the table to a 12" wheel, -39mm offset gives that wheel the 'Mopar backspace'. So, -44mm causes that wheel to fit the vehicle well...on the inside at least.
I have 8.5 wheels and 0 offset and it's tucked up in real good and doesn't stick out that much even with my 37 13.50 tires
