I am interested in putting the Kumho 315 70/R17 on my stock Sport S rims. I believe the stock rims are 8.5 inches in width and that's the minimum for these tires.
I spoke with a dealer who told me you should avoid using the minimum on the width range because you get a bad ride from that. he started explaining that the tires "balloon" and you don't have the sidewall supporting the weight as much as you should.
People put 315 tires on stock jk wheels no problem...the problem becomes the tires rubbing because the back spacing is not enough. Do you plan on using wheel spacers to push the wheels out farther?
Do you have a lift installed?
The GY Duratracs are one of the most popular tires out there. I know a lot of guys that run them. They are also one of the lighter and aggressive looking AT tires out there weighing only 60 lbs in the 315/70R17. This past year some "New" tires are coming out. Tires that cover the gap between AT tires and MT tires. Better suited for us guys that have a DD and like too off road on the weekends. Here are a couple of examples. Mickey Thompson Performance Tires & Wheels Dick Cepek Tires & Wheels
Falken also has a new tire coming out. - Falken’s new WildPeak MT. (They say it's pretty quiet)
All the above tires have a longer tread life than most MT's, are more aggressive than AT tires and are not as loud as most MT tires.
Good luck with your search! So many good tires to choose from.

Hey guys, I just posted a "rim width" question on another thread, only came across this one after.... In order not to double post, I would really like some of the great experience/advice I've been gathering off this forum!
I ordered the pro comp 7069 in a 16x8 wheel, and going with a 315/75/16 general grabber red letter tires. I'm hoping that the 4" back spacing is enough and not too much. It's a jkur lifted 2.5". Fenders are cut so I just need to cut my rock guards and punch seams. Will post pics after the wheels and tires get put on.
