235 80 17 tire feedback on a JK?

[David9962000]

Hi guys, I'm looking for real life experience feedback with a 235 80 17 tire. I have a 255/75 17 BG Goodrich KM load C on a 7.5 x 17 wheel now.

The 235 80 17 is a load E and I'm thinking of a K02.

Thank you.

Here's this for specs: https://www.tacomaworld.com/tirecalc?tires=235-80r17-255-75r17

I'm sure you've seen it though. I'm shopping for JKUR tires too, so I'm also interested. I'm guessing no lift since you're going to an overall smaller tire than stock?

Yes, no lift. I debating, skinny vs fat for the real world and some moderate trail activity. And 31.8 vs 32.08 overall diameter is very close.

Thanks for the link.

The extra volume in the 255/75 will make it ride much better with lower pressure for 4x4. You'll get a little better MPG from the narrow tire, which also looks better imo. basically a trade off between city and off road....

Ply rating is a function of inflation pressure, so unless you intend to inflate to higher pressures there is really nothing to gain, for example:

2 tires of same/similar dimensions on LR C one LR E
Both inflated to 60 psi, both carry identical load

Higher load range tires rarely offer any additional benefit in puncture resistance or abrasion resistance

Have you guys considered a 255/80R17? They fit on a stock wheel and are slightly taller than stock.

I did a review on the Toyo Open Country R/T's recently:

Problem with this argument is you cannot take a Load Range C tire to 60 psi. They are limited to 50 psi max whereas a Load Range E tire can go up to 80 psi where it can carry more load. So the LR E tire is designed to carry more pressure and therefore more load

I don't have any experience with the 235/80r17 ko2 I'm running 275/70r17 ko2 on my 2017 jku sport with stock suspension. I've been really impressed with how well they work on and off road. My dad has the same tire on his 14 jkur but he runs a leveling kit on his.

I wonder how it feels with narrower tires, I now the base Wrangler has a 225 all around. Anyone has been using that?

I'd be concerned with the negative effect on braking of the narrower tire, especially under load. What is the perceived benefit of dropping from a 255 or 265 stock JK tire width to 235?

This is a great calculator to play with when trying to figure out tire and wheel size and fit. http://www.rimsntires.com/specspro.jsp
