285/70/17 Duratracs to 315/70/17 Duratracs

Hey guys I'm running 285/70/17 Duratracs right now with teraflex performance leveling kit. Next week I will be installing a RK 2.5 Max Travel kit and looking to get bigger tires. My tires only have 2k miles on them right now so in your opinion is it worth upgrading to the 315/70/17 Duratracs? Is there enough size diffrence to justify a extra $500(if I can get $1k for current tires)? Thought about going to a true 35 but with this being my daily with 3.73's I'm not sure if that's the best route. Thanks!

The 315 is about 2 inches bigger in diameter...tire rack has a specs chart:
Goodyear*Wrangler DuraTrac
Click on the specs tab.

I did the same thing - 285 to 315 Duratracks and Teraflex leveling to 2.5". I never measured the 285s, they were so close to stock Rubi BFG KMs that I did not have any speedo issues.

Be warned, the 315 DTs will not come close 34.6 or whatever the nominal size listed, once mounted on the Jeep. Mine are 33.75" @ 30psi. Most people run these 28-32psi, and I've seen people report 33.5-34.0.

Would the 315/70's fit on a stock JKU with only the leveling kit installed?

Yeah I know. I went ahead and ordered them though. Did not want to add a lot of unsprung weight to the Jeep. Gaining 6 pounds on each corner which isn't too bad :-)

Yes they will although you may get a little rubbing offroad.

Dude, this is almost the same situation that I just went through (had cold feet with 35s and the 3.73).

I had the 1.5" performance leveling kit with OME shocks and duratrac 285/70/17. I actually just went up to the 2.5" TF coils with 5100 two weeks ago and 315/75/16 duratrac this week.

I have a 2013 and procal and honestly with the 315/75/16, I don't really notice a difference. My JKU is my daily driver. After driving it for the last two days, I'm averaging just 1mpg less than my old setup with 285/70/17. At 30psi, the tires are measuring to be 33.25"

You can run the 33s with the 2.5" lift, the duratracs are "beefier" looking tires. It doesn't look that bad... but if you're looking to go bigger, I say do it. You'll have regrets either way. But don't get me wrong, the 2.5" and 33s is a great setup.

Honestly, I have a 20 month old son and my wife is really short, so I thought the 1.5" and 33s were perfect, but after I started wheeling, I realized I wanted to go bigger in lift and tires. The problem was also the additional costs. I ended up going with the TF front control arms and JKS trackbar. You don't have to do it, but it makes a world of difference. If I were to do it all over again, I'd go 2.5" and 35s.

Good luck!

33s


35s

Just put the 315 70 17's on our JKU with level 8zx wheels. They fit with no rub except on the rubicon rock rails at the rear when the suspension compresses on a bump occasionally. The front clear with the stubby bumper and winch. I will be installing the 2.5" RK spring lift this week so hopefully there should be no issues with that being done.I am not sure if I will need to trim or shorten the Rubicon Rock Rails to clear at the rear tire when flexing after we lift it though.
