Nittos are usually pretty accurate on listed height compared to most so they are going to be at least an inch and half taller than stock.

 

Skinny 33's or 275/X/X (33"x11") on stock wheels are good with possible steer stop correction so tires don't rub control arms at full lock. Anything wider and you will rub. New wheels with 4.5" backspace and wide tires are good.

 

I like the B.F. Goodrich Mud-Terrain T/A KM2 LT255 75 17E

They fit on stock JKUR rims and require no modification. They are a a true 33" tall tire with good road grip, low noise, and very good mud/trail performance.

 

255 75R 17 tires work out to approximately 32" x 10" tires. I have a 2015 Rubicon running 285 70R 17 tires on the stock wheels. These tires work out to approximately 33" x 11.22". The only mod I did to prevent rubbing was adding 2 washers to the steering stops. No rubbing. Didn't have to trim plastic air dam.

 

My actual inflated total tire height with OEM JKUR and BFG KM2 LT255 75 17E were right at 33" (approx 37 psi). The only reason that I know this is because I measured them carefully when I set the AEV Procal.

The BFG All-Terrain T/A KO LT265 70 17C should be about 31.6" tall; I have not measured. The KM2 were probably better all around, and I may go back to them.

 

mine are 31 inches over all / stock is 32 "
