Hello new to the forum just want some advice on rims. If I decide to go with 35” tires on my Jeep with new rims what would be the correct offset used.

2018 JL rubicon 4dr looking at 3x12.5x17 tires and a 2” lif. No fender flares. I think I might get the FUEL vapor 17” rims

I went with the 4.53" backspace on my XD addict rims. They have Nitto trail Grapplers on them in a size of 35 12.5x17 on my 2017 JK sport. No rubbing at full turn but they do protrude a bit from my stock fender flares.

We don't use offset in the Jeep world, we use backspace. So, you need a wheel with between 5.2" and 4.5" of backspace. The 4.5 will stick out about 3/4" farther than the 5.2. I run 4.75" of backspace on my JK.

Backspacing ignore the wheel width so you can run the width that you like for the tires you choose. For 12.5 wides, I like a 9" wide wheel...

Thank you for all the help I will end up with the Fuel Vapor 17x9 rims with the 35” tires and a 4.5” backspace. BTW I like the look of the XD addict rims

Should I worry about the extra rotational weight per wheel, seems like it’s about 30LBS extra each wheel between the rim and tire

With my sport and a D30 up front it was my biggest concern so I didn't go too many miles on the 35s until I got an Artec Industries Front Armor kit welded on the front axle. It includes the truss pieces, gussets, etc. The concern I had most was that my Cs would get bent with the weight of the tires and I'd end up with a smiley face look from the front. With this kit it really beefs up the Cs as well as the axle itself. Now I don't worry much about hitting even moderate trails. I feel the stock D40 is fine for the 35s so I left it alone.

Eventually though I'd like to get a new set of front and rear axles with proper gearing that could handle even 37s if I ever want to try that, but that would require a whole bunch of other stuff to swap/upgrade.

You will be fine with 35's, the JL has improved Dana 44 axles. At my local 4 Wheel Parts store one of the employees has one with 40's for a year now, no issues, but this is flat Florida. No way I'd go bigger than 35's myself though.

I also believe the Rubi JL comes with bigger or better brakes than the Sahara or Sport; but someone please correct me if I'm wrong.

JL Rubi axles are much better than JK. I would be willing to run 37's... Might it break at some point? Maybe, but you can break anything if you try hard enough.

I have 315 70 17 KO2’s on Method wheels with 4.75 backspacing. On the front I would say they stick out a good inch, maybe more.
