Just had the guys at 4 wheel parts in Va beach install the set up for me. 315/70r17 duratrac with procomp series 5034s.

No rubbing at all. But had to take the ends off the front bumber to clear when turning. Vehicle still seems to maintain its liveliness. Speedometer is off by 7 (actual speed 65 and speedometer reads 72) give or take a few.

There is a slight hum coming from the wheels at highway speed but nothing unbearable. Music set to 20 will drown it out easily. I haven’t got a chance to install the RC 2.5 budget boost yet. But once I’m done I’ll update you guys.

Is it bad I’m already thinking about 37s . #neversatisfied
Nice, I'm about to have my 35s installed this weekend.
If you are doing your RC 2.5" lift yourself, see my review for potential tips: https://www.jlwranglerforums.com/fo...ep-suspension-lift-kit-2018-wrangler-jl.4411/

Yes. My back spacing is 4.75 on the new wheels and evidently it couldn’t be mounted without a relocation bracket. I’ll be giving it a try myself shortly though so I’ll let you know

So after trying to install the spare tire myself, I’ve confirm that for some reason my 315s are too wide, it hits the bumper before I can even close the tailgate. There is no forcing it in there. Rough Country relocation bracket has been ordered.

They look good on your factory wheels any reason you switched up to pro comp except for aesthetics? I would like to run a similar tote on my factory wheel but haven’t seen many pictures on the Sport wheels so thanks.

It’s not just aesthetics. The factory wheels backspacing isn’t wide enough to run much bigger tires without wheel spacers.

The wheels and tires look great. I was concerned about the performance drop with the 3.45 gearing. The MPG suffer much?

Yeah definitely. I did a 2.5 budget boost also. I went from 18.5 to 16.5. Performance was still good though. Haven’t noticed much decrease in performance from the butt dyno

@s.i JEEP looks good! How did things go driving around town without the lift on?

Could you snap some photos showing how far out your tires are sticking from the fenders? I’m trying to pick out what to go with for myself and would love to use your setup as a “baseline” to compare other options to.

Good thread as I'm getting my 315's installed next week. Did you ever post up pics after adding the RC boost?

My setup will be:

315/70/17 BFG KO2's
Stock Rubicon wheels
1.5" spidertrax spacers
RC relocation bracket
2.5 EVO budget boost w/shock and control arm relocation brackets

Seems like I have everything covered.
