35's and Rubicon Rims

[brianinca]

It helps to have a pit crew with 35's:

The 315/70/17's are the stock tire size in this picture, but since the tire/wheel isn't on a bumper carrier, it's easier to change on the Gladiator. The stock scissor jack is mostly for roadside use in my book, I have a bottle jack/jack stand combo in one of the gear boxes I keep on board. CERTAINLY the factory jack is useable, but it is not expensive to get a MUCH better jack - you don't need the $500 offroad aluminum big wheel racing jack:

Yea I actually have 5 Rubicon Rims. The spare rim is a Rubicon rim also. If I ever did get a flat its just an easy swap out. On another note is it difficult to change a tire that size. Never have had to. All I got is that junky little jack on the seat that came with the truck

I had dealer swap on BFG KO2s, 35x12.5, right out of the gate. Just crossed 1 year and 20k miles, snow, rain, trails, sand, rock, dry highway, not a single issue from 38 to 15 psi as needed.

I’ve got a diesel on a 2-inch Mopar lift, and I get 27 mpg on the highway, and average 23.5.

Echo what someone wrote above, just drop a few psi to flatten the tread (I run 36 on highway) and all will be fine.

I usually run 36-37 on my 33's currently

Yea was looking at getting a good bottle jack to keep regardless what tires.

What kind of mpg are you getting with them running at 30 PSI

low 20's and mid 20's on a run. It is billiard table flat here though.

Was talking to the folks at DIscount tire and they told me they won't mount the 35's on the stock Rubicon Rims. Say I need a wider rim. Guess I could always try to find someone to mount them and just buy the tires or stick with the 33's. Don't really want to go to new rims. Ah decisions decisions.

Discount tire mounted 35/12.5/17 on my Rubicon rims, even tho manufacture specifies 8 min.

When my 2020 Gladiator Rubicon Launch Edition arrived at the dealer, I had the 35" Falken Wild Peak tires removed by the dealer and had them install 37" BF Goodrich KM3 Mud Terrain A/T tires. They fit on the Mopar rims. I like the tires as they are wearing well, don't make a lot of noise and look attractive. Anyway, hope this helps.

I have 35x11.50r17 nitto trail grapplers, fit excellent, ride great, fairly quiet for MT, I also got a 5th alloy for a spare, just haven’t decided how to carry it yet

Why not carry the spare underneath?

I also went with the Nitto Trail Grappers 35x11.5xr17...love them thus far, great tire and within specs for factory rims.

Tire rack and my local dealer told me that the 35's would not work on the stock 7.5 rim because the sidewall sticks out and weakens the sidewall. Recommended wider rims.

The Nitto Trail Grappler 35*11.5*17 are rated for 7.5" rim. I believe you could even go down to a 7" rim.

Tens of Thousands of people running a 7” or 7.5” rim with a 12.5” wide tire says your dealer and tire rack are wrong.

Personally, I have over 200,000 miles of real world experience.

Not one failure due to rim size. Not towing 5,000lbs, running just a wee bit above the speed limit in 100+ weather, snow, ice, rocks, mud, you name it.

Only failure was due to a concrete block in the highway, no where to go.
A nail.
Neither are rim related.

I don’t think anyone is saying you can’t do it, and that many haven’t done it.
The FACT is no tire manufacturer that makes a 315mm or 12.5” wide 35” or 37” tire lists it as being able to be mounted on a 7.5” wide rim. This is why some places will not mount them on stock rims due to liability and using the tire in a manner outside the manufacturer’s intended use parameters.

Why not carry the spare underneath?

It doesn’t fit the center of the alloy wheel, it’s smaller than the steel wheel that comes with it. Also I live in Maine, lots of salt in the winter, I have a hard cover, I secure it in the bed.

I'm running 35 x 12.5's on stock rims with no issues what so ever. Falken Wildpeak MT's, 35x12.50r17. Purchased and installed by America's Tire with full warranty. I've been very pleased on and off road.
