Hi all,
I recently purchased a 1998 Wrangler Sport and want to purchase new rims and tires. Right now my Jeep has Goodyear Radials p235/75r15, and I found a set of Goodyears p255/75r17. Would those fit without having to make any modifications?
 
Nope. So the 75 is the “ratio” size
It’s how much meat is on the sidewall of the tire, the first size you listed has a diameter around 28 inches
The 255/75/17 has a diameter around 32 inches. No way to pull that off without a lift. If you want to get a larger diameter rim you would have to reduce the ratio size to around 65 to get a 30 inch diameter tire, which is about the max you can do stock. You may be able to squeeze a 31 in but that’s about it.

You should be OK with 31X10.50R15. It is what I have on mine. They may rub a bit at full lock on the steering but you can add a washer or two behind the steering stops to limit the turn so they don't rub. If you have disconnects for your sway bar you may also rub slightly at full flex but it has not been an issue for me.

Darn, that sucks. Found a really great deal on a set and was hoping they would work. Guess I’ll have to keep looking lol

I'm running 265/70/17 on my LJ. That works out to 31.6" diameter and an 1" more width than stock. For street driving they have not shown any sign of rubbing or fender contact going over speed bumps at normal speeds. Won't try them on anything more challenging till a 1 1/4" body lift is installed shortly to be safer. Consensus seems to be that a 2" spring lift is needed to do any challenging off road with that tire/wheel combination. One pleasant surprise is the tire/wheel change cured a rubbing issue on the sway bar linkage at full lock that I had with the stock 30/9.5/15 stock tire size. JK/JL/JT rims require a wheel adapter to fit the newer lug pattern and compensate for the reduced set back on those wheels.

People run oversized tires without the proper amount of lift all the time. What's another 1/2"? :rolleyes:
However, I wouldn't recommend it to someone without knowing the wheel size, spacer size, and how/where it's going to be driven.

It's why some of us try to encourage cycling the axles without springs. It takes the mystery out of what fits and what doesn't.

My 2000 has only a 1.25'' body lift with 265x70x17'' Maxxis Razr AT, with no rub.
