I have 315/70/17 on pintlers with a 2.5 RK lift. It has duratracs on it. Rides great. Did have to go with 1.5 inch synergy wheel spacers. Because of the backspacing I went with spacers. The rim came too close to the rear suspension for my liking. It does ride great. It has 3.21 gears so it will b reheated soon. It is a dog with those gears but there only so much money in the wife's wallet. Lol. Hope that helps

I went with a 3.5" RK lift, and the 315/75R/16 Duratracs. They measure out to 34.5" at 33PSI.. Love the look and the ride. They do rub a bit when I have them WAY aired down. Like 8PSI but other than that they are great. I get about the same millage I was getting which is crappy, but hey it's a jeep and it's a 3.8L at that.. The Tires, wheels and weights come in right at 90.5lbs a tire. I went with the 16" wheels to get a little more sidewall for airing down..

I went with 285/75/17s over the 315/70/17s for a couple of reasons....
I wanted a tire that didn't stick out quite as far.
I wanted a lighter weight tire.
By doing so I saved about $60 per tire - that is quite a savings for 5 tires with not much difference in size. The biggest size difference is the 285s are about 1 inch smaller in width.
Our 285 barely fit on the stock carrier/bumper. It actually sat on the bumper ever so slightly. So yes it fits but it is a tight squeeze. The picture doesn't show the stock set up because we got a new bumper.
As for mpg - well I just don't bother looking any more.

: )

Are you running spacers?

Looks great! Did you regear? What gear ratio do you have and what kind of mileage do you think you're getting?

Lots of good advice on this thread. My question and request....pintlers with 285/70/17 either BFG or Duatracs will this fit without a lift? If anyone has this setup I'd love to see some pics.

285/70/17 BFG KM2 no lift, 1.5" wheel spacers no rubbing anywhere. Not exactly what you were asking for, but hope it help.

285's with a Terraflex leveling kit and wheel spacers. Drives no different than stock and didn't notice any mileage difference.

It will fit great. The pintlers have the right back spacing so you won't need the lift. I have the 285/70/17 with the savegres and the BFG, no lift, no rubbing, looks awesome. Can't post a pic just now, but if you search posts by my name you'll find pics.

Do it up!

I kept saying only 33's for me....year later I sold them and put 35's on, looks so much better. If I had it to do over again, I would have gone right to the 315/70/17's from the start.

285/70/17 Duratracs on Pintlers before Performance leveling kit.
Slight 2 min trim to air dam to correct little rub on driver side in reverse.

I went from 255/75/17 to 315/70/17 with stock rims, 1.5" spacers, and a 2.5" lift. Love the setup and would not change it. I also went from mud tires to all terrains since I drive 80-100 miles per day onroad. Lost less than 1 mpg regarding mileage and gained a more solid, comfortable ride. I don't regret it for a second.

Here's mine with pintlers, 285/70/17 duratracs, & a Teraflex leveling kit. I drove around for a while with these without the leveling kit and only rubbed on the air dam at full lock. However, like most others have said, I wish I had gone with the 315's......especially now that I have an AEV 2.5 inch lift going on in a few weeks....

I had my mind set on 285/75 17 Duratracs on black level 8 zx's until I read this thread... Now I'm seriously considering 315's! I'll just be running the tf leveling kit.

Any recommended sleeves/gussets? Are they requied since i have the Sport/base model? Any other necessary mods to run the 315's?
What to do, what to do?

Edit: Maybe that was a moment of weakness, I can't really justify the extra cost and required work, sticking with the 285/75-17's...... For now :-)

Here's the difference if it helps, 275/70/18 (same as 285/70/17) vs 315/70/17, same tires (Duratracs). Both have a Teraflex 1.5" leveling kit, the 275s picture was with 19/60 springs and the 315 picture is with 10A springs.

jwilson,

Are you getting any rub with the Pintlers and 315s? You do not mention wheel spacers so I assume you are only backspacing with the Pintlers, right?

So far no, but I haven't flexed I out. On road everything is fine. And you are correct, do not have any spacers, just the wheels.
