Miracle Grow!

Hey all,
Its time to put our 2019 JL on Miracle Grow and get the parts list together.
I know that it is getting Nitto Terra Grapplers G2 in a 35x12.5 R17, but my question is will this tire work on the stock JLU Sport wheels. I like the wheels and they already have some rock scars on them. Also if I can use the OE wheels that leaves more money for the build.

TIA
Dan

It depends. Most tire manufacturers do not recommend a 12.5-inch wide tire be mounted on a 7.5-inch wide rim. So you will need to find a tire retailer willing to do it.

Good luck.

I was wondering about that, I guess if it comes down to it I can try to find a narrower tire or buy a set of wider wheels.

To retain the OE rims you will need a set of wheel spacers, which run about $200.

I’d look into a new set of wheels, with the proper width and backspacing. By the time you save on the spacers and resell your OE wheels, a new set of wheels won’t set you back all that much.

I’ve had good luck with Quadratec’s own line of wheels over the years. They come in the corrrect specs, are well made, are relatively lightweight, look stock and are priced right.

I run 35x 12.50's on my OE wheels but get this.... I buy the tires from the tire guy, wait for them to come in. Schedule the install day, drop off the Jeep and start walking to go get some breakfast.
2 miles down the road my phone rings. " Uhh Hey it's John up at the tire shop. We have a problem. I didn't know your Jeep had 7.5" wheels I just assumed... blahblahblah...

I said, "John you gotta be kidding me. You SOLD me the tires. I Never hid the year/make/model of what I was putting them on now I'm 2 f'ing miles away.....

He offers to come pick me up...

Anyway. Across the street is his competitor (I like them, I would have bought the tires there if they had carried them) I took the Jeep and the tires across the street and they mounted them.

So, Yes. Get Everything ironed out and agreed upon up front. Assume the guy you are talking to is a moron (like John) and you'll be safe.

Moral that day and today: I'm still alive. The tires fit and work just fine on my wheels. I have a JLUR w/2" Rancho lift and 315/70-17's on my JLUR OE wheels.

Here is another question.
Will the stock rear tire carrier support the size and weight of a 35" spare?

should be able too, however depending the backspacing may not fit.. also you want to make sure the tire is hitting the little bumper things so it can't move around,movement is what cause the issues with the bigger tires.

Ehhh that's one of those "It depends". I ended up installing the RedRock kit - for the money it is a nice set-up. My 35" Fit But it rested on the bumper. I think it started to sag as well after awhile.
I also bought and installed larger baby bumpers - all in all it all worked out

Both parts work together as a nicely designed unit.

Then I got these too

It is well documented that you can fit 35” tires on a JL Rubicon without a lift, and you can fit 35” tires on a Sport with a 2” lift.

So the question now is: can you fit 35” tires on a lifted JL Sport reusing OE wheels without rubbing?

Going to depend on the choice of tire as well as usage (rock crawling vs DD) probably...

* If you get a rub it may be at full lock (obviously low speed) on the sway bar - not usually a big deal sounds worse than it is ...
IF you do it and it rubs you pick up a set of spacers

The original concern was putting a 12.5 inch wide tire on a 7.5 wide wheel.

Understood. But if the OE wheels make the 12.5 tires to rub you need to know that too, don't you?

Yes, we do want to avoid rubbing. However after some research I have decided to just go with a new 17x9 wheel.
