hi everyone
i have been using this forum from the day i was thinking of buying my first jeep. as i am getting close to the delivery, i have a question about upgrading tires.

i have ordered a 2022 Wrangler JL Rubicon 3.6L V6 Manual 6SP with 4.88 Rear Axle Ratio.

i've been reading/learning about gear ratios, best ratio based on tire size etc. as the rubicon comes with 33" from the factory, i was reading that 4.88 is little too much for 33", and the best combination will be 37" tires. my initial thought was i will enjoy my stock config for sometime and i will slowly think of upgrades. but as i am getting closer to delivery of my jeep i was having a thought of at least just the tire upgrade to 35" from the showroom itself. i would love to hear the valuable suggestions/advice from the experts here.

note: i also have hinge gate reinforcement in my original order.

basically my questions are:

is it even possible to just upgrade from 33" to 35" without any lift ? (if not, end of my questions)
if yes, will it scrape in any condition considering all road/off-road conditions with maximum articulation ?
does it void the warranty ?
is there any advantage in doing this before i take delivery? do i save on tires?
what's the best tire option which is close the factory tire, i am just looking for bigger size( not any more aggressive, something all terrain)

thanks in advance.

Yes.

Will it scrape in any condition considering all road/off-road conditions with maximum articulation ?

From what I have read, yes, 35"s will rub when articulated to extreme.

Does it void the warranty ?

No.

Is there any advantage in doing this before i take delivery? do i save on tires?

It's nice picking up your new purchase "read to go". I asked for the Mopar bead-lock rims for example that were dealer installed prior to delivery. All the "special requests" were taken care of prior to delivery.

I have been very impressed with the BFG KO2's both off and on the road.

IIRC….the JL rubicon can fit 35’s without a lift. Particularly if you stay with BFG KO2s as they do not measure a true 35”. Fairly certain 37” would require a lift. Great tires nonetheless….tho mine are 32” size on my JKU. Someone with more personal knowledge of the JL models & gearing can elaborate more

thank you @T.G. and @Fantus33 . i will keep researching as my jeep arrives.

so what is the max tire can go by 17" wheel? does 37 requires wheel change ? i was assuming at least 35 will go on the same stock wheel ?

You will require new wheels with 35s. Those tires are too wide for the stock 7.5-inch wide wheels. And, apparently, 35s will rub with the stock wheels, anyway.

You need wheels that are at least 8.5 inches wide and have 5.2 inches of backspacing or less.

Most AEV and Quadratec wheels meet those exact requirements.

If you decide to get new wheels through your dealer, Mopar offers these attractive wheels. They have the correct specs.

You can order a them with a 4.88 gear? That's the first I've heard of it and pretty cool if so.

yeah they introduced that in 2022 and i guess only on manual. but they didnt give an option for 35". otherwise i would be all set with things i wanted from factory factory itself.

Honestly, you are better off taking care of the wheels and tires yourself. Auto dealers don’t normally do tire work, anyway. They will take your Jeep down to the nearest tire shop. The only thing they do is rotations. And Jeep dealers are notorious for refusing to rotate the spare tire.

You will be able to resell your Rubicon wheels and tires in a split second. Check Craigslist and Marketplace for going prices. But $1,500 shouldn’t be hard.

I’d order the wheels from Quadratec and get the tires from Discount Tire. Discount Tire will rebalance, rotate and patch them for free, at any of their stores.

Or you can order the Mopar wheels online and do the same: go to Discount Tire and have them take care of the rest.

BAM normally has the best Mopar prices online: Mopar Jeep Wrangler and Gladiator 17 Inch Satin Carbon Wheel Off-Road Mopar Genuine OEM 77072494AB | Auto Parts. Keep in mind most Mopar sales online add shipping.

Also, Morris 4x4 and Northridge 4x4 are active sponsors on here. Check what they offer.

PS - depending on the wheels you get, you might need a new set of lug nuts. JL’s lug nuts are wider than JK’s, so they might not fit some aftermarket wheels. Allow $40-$50 for a new set.

Yeah, I wouldn’t bother with beadlocks. They are heavy, expensive, require careful torqueing; they are aimed at extreme off-road situations. For 99% of the time, regular 17x8.5 alloys will do the trick.

good to know!
what kind of "air down" can you do with the alloys?/ PSI wise? I was thinking I needed these

You can air down safely to 15 PSI. I’ve seen people claim that they air down to 10 PSI. I don’t venture that low myself.

That’s pushing it, though. Every tire manufacturer, and national tire retailer, recommends mounting tires that are 12.5-inch/315mm wide on rims that are at least 8.5 inches wide.

OE rims are only 7.5 inches wide. While they will “fit,” it is not recommended. Even less if you plan to air down.

thats what i am thinking now.. what i wanted to do was just the tire change.. nothing else.
but now i can see from your messages that just the tire change is not enough to make it perfect.

if i have to change wheel(rim) may be i will keep 33 for sometime.. i will get to feel my jeep and later i will of 37 with lift instead of 35. i hope 2inch lift is good enough for 37. i dont like very tall looking jeep.
