JLU Rubicon - 35 Inch tires with no Lift?

[supamyk]

I love the look of my 35s with -12 but I definitely wasn't prepared for how much they fling up!

Looking damn good though

I agree! It does!

That's one of the reasons why I went back to a stock wheel offset when I moved to 35's.

2019 JLU Rubicon, (steel bumpers) is ordered - I'm considering changing rubber to 35's right out of the gate. I like the meatier look, and it will add an inch of ground clearance. If I'm going to order tires, it needs to be before end of the year.
My variables:
Keeping stock base rims
No lift (Don't want one)
Don't care about fuel economy
Road noise (Initially and when they get more worn) is a concern
Don't want spacers

Pondering:
BFG KO2 in 315 70 17
Nitto Ridge Grappler 35 12.5 17

Can I do these without rubbing?
Will the tailgate and spare tire carrier function properly?
Load Range C,or E?

Given my parameters, is there any reason not to do this?

Appreciate your input.

Cheers,
James

Yep, your good. Ran 35's for a while before I threw a lift on.

If you run 35s without a regear in a rubicon does it damage your transmission if you don’t off road? Manual if that makes any difference?

No. Won’t damage it if you do, either.

Fling up what rocks? Dirt?

Road spray mainly. It sucks soaking your own windshield

Nope, that's what the 4.10 gears are for. No need to bother regearing. What you may notice is that the 8-speed tranny might slip in and out of 8th on the highway depending on the grade. However really hasn't hurt my MPG much, if at all. The lower gearing is meant to help out with bigger tires. Keep in mind too, that the JL was designed around 35's.

That's good. I have a manual tranny and i notice only a slight change in when to shift, but otherwise seems to be ok. But it's only been a few days with the 35s so still getting used to it.
I am not spending any more money on this jeep. lol. I think if i told my husband i needed to regear, he'd divorce me.

Too funny, and all quite understandable. Either way, enjoy! The only other reason to regear is to get some really low gearing while offroading. I do offroad a few times a month but will never likely regear since I don't rock crawl, just trails.

I have another question. I know I have to get the speedometer calibrated. Does the recalibration help with the tachometer and shifting? It's a little confusing because i know it helps with the automatic because of the electronics with the transmission but does it help on a manual?
I do feel it's a bit sluggish. will recalibration help?

 

[LLRubylady]

You’ll do much better selling those wheels and tires yourself as a set, as new take offs, than whatever the dealer will give as credit. The upgraded wheels with tires and tpms you could sell for $1500+ I bet. I sold my standard rubi wheel setup for $1,100 and the sold the same day I listed it for sale.

Marky, you have a 6 speed manual like me. Did you notice a change in acceleration and shifting with your KO2 upgrades?

Not sure about the sluggishness as I drove mine around before I installed the TazerJL, and, of course after, for the speedometer calibration. I did not notice any change in the vehicle being sluggish, however, I do have the automatic. Calibrating the speedometer will help, but I doubt it has an effect on the tranny in a manual vehicle. If your unhappy with the fact that it seems sluggish to you, a regear will help with that, perhaps stepping into 4.88 gears but I would do a bit of research if that's the route you'd like to proceed with. Your gas mileage on the highway will suffer from a regear, but it would feel better around town.

Ok so here’s mine. Method 305’s 17” 4.5 backspace, 35x12.50 Toyo MTs. No rubbing, but it’s too close for me when turned and stuffed. I’ll probably order the Dynatrac EnduroSport 2”. I don’t want my center of gravity too high, I tend to drive too fast in the desert.

I swapped my tires out when it had like 21 miles, and half of those miles were from dealer prep/test drive. I don’t really know any different than what it is like now.

I know for certain that the acceleration is WAY better than the Jeep I sold when I got the new one. The old one was a 2011 with the 3.8L, 33” tires, and 3.73 gearing.

This new Rubicon accelerates plenty good in my opinion with the manual transmission, 35” tires, and 4.10 gears.
