JLU Rubicon on 35s no lift

[Fsttanks]

Looks good. Are those C rated? Any notable difference in ride?

Yes they are “C” rated. Made that a point after living with “D” and “E” rated tires on my last Wrangler for several years. The factory 285s KO2s are “C” rated and seem to prove rather rough from what I have seen of them so that helped me to take the leap to a “C”.

Ride vs factory tires is slightly different, but I have not tuned the tires PSI setting fully. They are currently at 35 PSI “warm” and I think 32 PSI “warm” should be about right to match the factory feel. But 32 PSI when cold will place them very close to the threshold of setting the TPMS off.

Handling is improved. The wider contact surface really makes a difference especially in high speed turns such as freeway overpasses. Sticks like glue now.

Pedal throttle response “feel” is more to my liking now. I found the with 285s it was very touchy and overly response around town in stop and go city driving. The 315s have taken much of touchiness away yet I have lost no acceleration when needed. I am interested in seeing if when I adjust the speedometer to match the new tire size if the throttle “feel” will change back close to what is was with the 285 tires.

Waited a month to install “35s” on our JLUR. Going to stick with the stock rims as I did before on my JKU but this time I see no need for spacers. Fit is near perfect IMO with no rubbing on control arms at wheel lock to wheel lock while moving forward and in reverse.

Interesting was the expected yet minor indicated speed change comparison between the speedometer and stand alone GPS. It showed 35mph = 36.5, 66mph = 70.1 and 70mph = 74.5. Granted I was going from 285s “33s” to 315s “35s” and I suspect the difference would be more for a JL/U with the slightly smaller factors 265 tires.

I will be correcting the speedometer with an AEV Snap shortly.

Below “35s” on stock rims no spacer or lift.

A note on this last photo above the wheel is not bent outward, it just looks that way do to the angle of the photo.

Are these 35x12.50R17 or LT315/70R17? Love the look of you JL!

They are 315s. The difference between the two sizes for BFG KO2s in total diameter is 34.41” (315) and 34.6” (35x12.5x17). This works out to 1/10 of an inch taller for the 35 vs 315 when mounted on the Jeep and at the same PSI.

The 35x12.5s have a higher load rating I believe they are “E” rated If I remember. Definitely not “C” rated. So they will be a much stiffer at all PSI levels.

Note: All brands of “35s” are never 35” they range from 34.3 up to 34.7 depending on brand and tread design. True “35s” are actually “37s” which range on average between 35.4 to 35.8 depending on brand and tread type.

Obviously this is a matter of taste, but I think that a lifted JLUR with 35s looks undertired - too much gap to the fender. It will take 37s to really fill out the wheel wells and balance things out. I'm going unlifted with 35s.

Agreed. More fender gap than what's needed to clear the tires at full flex makes it undertired. And too little of gap looks too stuffed and neuteres is off road capability.

I originally thought anything larger than 35's would make the Jeep feel like a pig, so i went with the 315 ko2's and chose the Dynatrac "true 2 inch" lift to not end up with more than advertised. I was very wrong, because the Jeep didn't even notice the slightly larger tires. I want/need more ground clearance so now I'm on 38x13.50's with chopped fenders and am getting the rest of my 3.5" lift parts this coming Monday to regain full flexibility.

Here's some pics of fully stock, stock with 35's, 2" lift with 35's (only one i have before front fender chop), and 2" lift with 38's and chopped fenders.

This post presents the best contrast of the various solutions that I've seen yet. Thanks!

Great comparison

They don't.

What PSI are you running in them

 

[Kimmel]

I am new to the forum, and I was wondering if anyone is running Fuel, Rebel 5 rims on their Rubicon? I was looking to purchase a set of these rims in 18s. My plan is to follow suit on this thread without lifting my vehicle and adding 35s (Nitto Ridge Grapplers: 35x12.50R18). Also, I was curious on what offset to run: 1, 20, or -12? I don't plan on doing extreme off-roading at this time. I may add the standard 2 inch Mopar lift down the road. Any insight or advice would be appreciated...

 

[Foggy47]

I don't know about your wheels......but I did use those same tires with Method wheels on my JLUR.....and think the tires are just right for me. I likely wheel much like you.....and think the Nitto Ridge Grapplers are a good tire for my needs. Not sure if I will ever lift my Jeep..... I am resisting a lift. I have not had rub issues with my set-up with moderate trail use.. I have heavy bumpers front and rear and a winch and after-market sliders and carry quite a bit of extra gear. Will be adding skid plates very soon. If I do experience rub issues.....I may add a lift kit.....but I am trying to refrain from getting any higher. So far - so good.

Have my 2021 JLUR on order. Steel bumpers. Going to have 315/70/17's put on as soon as it arrives and debating on a 1.75 rancho express level kit for the front. My unknown is the height from the ground to the door. Can anyone do a quick measure for me. That will help me choose on the level kit and steps/sliders so the wife can still get in

Adding mine, a wheel that I couldn't find any pics on a Wrangler.

Different angle, specs in post above.

This is with no lift. Next week I'm installing a Teraflex leveling kit to add a more aggressive stance. [AEV Borah wheels in onyx]

I am going with the same setup in about 3 weeks along with Teraflex 1.5. Did you have to do anything with your spare tire carrier or did everything work out ok?

On my past two Jeeps (JKs) I used the AEV tire carrier, but they’re still not out for the JL. Instead I ordered it with the Mopar reinforcement kit and added a Teraflex spare relocation bracket. That is one of the best engineered pieces of aftermarket equipment I’ve seen for Jeeps. In another league entirely than Mopar’s version of the same. Costly, but well worth it. That said, do not rely on the stock carrier not to break.
