jadmt Go at least 265/75-16. I first put 245/75-16 on and they looked wimpy. I then went 265/75 and they were better. I ended up with 285/74-16's.

SnowboarderOx I use this site:

Tire Dimensions Made Simple - Discount Tire

FYI: with your specs it says:
If your speedometer reads: 65 You're going approximately: 67.2

Jag That's a very small increase. You won't need to worry about axles or backspacing but your speedometer will be about 4% slow. That shouldn't be enough to significantly impact an automatic's shift points or other stability features, but the legal thing to do would be to correct it for the sake of the odometer. You can do so with something like a ProCal:

AEV - American Expedition Vehicles - ProCal Module - Quadratec

Just to give you an idea, people put 35" tires on stock JKs without any lift and on the stock axles (Rubi or otherwise). Not the best solution if it's going to be wheeled, but certainly possible.

Math Check on tires for 2013 Sport

Currently running stock tires on the 2013 Jeep 2dr sport, 225/75/16 and am looking to put on 245/75/16 (hopefully a tad beefier look).

I wanted to check to be sure this can be done on those rims without any issues or need of a lift or backspacing. Will I have to do some factory reset based on the larger tires (I read about that) with odometer, speedometer, etc.

Should I be concerned with axles or anything of that nature?

I plan on lifting in a year or so, but for now just going for some better tires.

Thank you for your help!
