Recommanded tire sze help
I have a rubicon 2013 2 door

It's an automatic and I have the 4.10 axle
It has the standard wheel/ tire on it and what I would like to know
It what is the biggest tire I can run with without doing and axle upgrades?

I found a post with a tire size to gear showing what was good for daily driving vs full time OD and then rock crawling and higher elevation.

So again I'm new to Jeep's and off roading so please tollarate my lack of not understanding.

On the rubicon 2013 Automatic with an axle of 4.10 with a 32 inch tire (standard) the chart shows me in the Blue which reads "Performance gear set for tire size, fair daily driver, full time OD use, Rock crawling and higher elevations"

Now if I go to a 33" or 35" tire that puts me into the Green which reads "Acceptable gear set for tire size, good daily driver, full time OD use, moderate trail use and changing elevations"

So what does all this mean? To me it sounds like it will perform off road with the standard tires better than it will with the 33's or 35's right? I dont know. But since it will be a daily driver more than offroad would the larger tire make more sense?

please help

and sorry for being a pain.

Like you I'm doing a lot of reading and trying to get a better understanding. Your 4.10's give you a lot of options though. From what I've been reading going to the 33" won't be a huge impact and would need only a 2" lift for clearance, you'll need more like a 2.5" lift for the 35" the 35's also impact your speedometer as the Jeep computer can only be adjusted up to 28s. - I've got the 18" wheels which is my limiting factor but I'm looking at going to 33" and new 17" rims.

So what will going to the 33 actually do for me? If I'm already running a 32 stock why would 1 go for a 33?

Keep you from having to do any axle work like you wanted. You can fit 33's with no lift on a jk an 35's with a 2.5" lift. If you get 35's it'll impact your mpg, give you a loss in power(should be fine with the 4.10's), you should atleast gusset your c's on your axle to keep them from bending from the extra weight, if you offroad at all then you should probably sleeve the axle as well.
