Hey guys,

I'm new to the forum and the jeep community (came from a Volkswagen Golf TDI - talk about opposite mpgs lol) and have been searching for a few days now to try and come up with a solid answer and I keep finding yays and nays.

A local guy has a set of 16x8 Rock Crawler D Slots with 4.5 back spacing.
I would like to run 315/70r16 tires (maybe KO2s) but don't want any rubbing or issues at full locks
My JKU is not lifted and I would rather keep it that way personally.

Do you guys feel or have any 100% yes answers that this set up can be ran with no lift and no rubbing?

Sorry for adding to the multitude of wheel and tire threads in advance

 

There is absolutely no such thing as a 100% yes or no answer, too many variables...


The backspacing 'should' be fine for clearance with the frame/components, but those 35 inch tires will probably rip the fenders off when stuffed. Look at flat fenders at a minimum, maybe taller bumpstops, or a small lift.

 

Thanks for the reply.
Now with that being said, if I were to run a 305/70r16 or even something like a 295/70r16, do you feel I could get away from lifting it? I don't have a problem trimming away some of the air dam if needed but I'd like to leave as much of the suspension stock as possible.

 

Run the 35's with flat fenders and a leveling kit

 

Did you mean 75r16? Run the numbers through a converter:

305/70r16 = 32.8 x 12
295/70r16 = 32.3 x 11.6

When talking about tire size and what will fit 'your' specific build, you should try to factor in the variables. The mfg's listed spec. The rim width. The weight of the vehicle. The sidewall stiffness. The psi. Whatever else. And when you see people posting measurements, did they measure a front tire under load, or the spare? Were they just regurgitating the mfg spec? Was the tire pumped up to 50 psi from the shop, or was it at 30 psi for normal street driving? You may find that the shiny new 35's you just bought measure out to 33.5" under your jeep. (Completely normal, many people just don't make the connection.)

Anyway, none of us can fill in the variables for you. That is something you have to do. Try to find actual measurements for the specific tire you choose (not just the number on the sidewall, but the specific tire from that specific mfg), and you will have a better idea of how much trimming you might, or might not, need. As noted, if you want 35's, be prepared to chop your flares or move to flats. If you are going to play the what if game with slightly smaller sizes, do your homework.
