Ok so I have been doing searches for weeks and still can't decide. I have a 2013 jku Sahara and 99% sure 3.21 gears and just added a 2.5 aev lift. I also have a set of mickey thompson sidebitter wheels. Now I am dead set on Duratracs as they will be the best tire for my use ( DD weekend toy exploring rig) and they are winter rated witch I need here in quebec Canada by law.
My real problem is do I go with
I'm worried the 285 will look too small. But will fit on the stock tire carrier.
And the 315 will make me suffer as I will not be able to do a re gear till spring also I have read conflicting posts that the extra weight will cause damage to my front axel.
Bump. Anyone else can share their thoughts or experience. I will prob do the 315 and re gear in spring as it has been stated before nothing is worse than spending a bunch on tires and then thinking they are too small.
Ok so I guess the next question is will my front axel bend or blow up with the 315's I know the stock Sahara wheel and tire weighs in around 72lbs. And the 315 duratrac is 60lbs add my 32lbs mickey thompson and the new package will be 92lbs. I do know that 20lbs will hurt gas milage and I don't really care I only drive in to work 3 days a week ( 50km there 50km back so 100km each day all highway) the rest of the time just putting around town or exploring the countryside. I just don't want to damage anything if it can be prevented.
I struggled with this decision as well for the past year and after 16000 kms on my stock mud terrains finally decided on 285-70/17 duratracs. While i would have liked to go with 315s i have now added so much aftermarket gear (including aev lift, bumpers, wheels) that my jeep is hundreds of pounds heavier and fuel economy is running around 17 mpg - and i don't want to see it drop further. Having to trim pinch seams and deal with tire rubbing on full lock etc are all things I didn't want to deal with at this time of year either. Being from MB i too needed a winter-rated tire and thus the DT's. I should have taken a close look at the Adventure Kevlars as well but I think the DTs will serve me well next summer. One (nice?) thing is i can hear wind noise now and not just tire noise - the DTs are much quieter.
Here are some pictures. First is with 265's and next are with 315's
I'm in the same boat w/2.5" lift but not sure about tire size. I've got 4.10 gears so not to worried about 315's slowing me down. That last picture has basically sold me, that's a really good looking setup.
Ok so I have decided to go with the 285's for my use right now I think they will work out better for now. And while driving around on them I can take that time to upgrade my gears, reinforce my front axel and get a tire carrier to do the 35's right.
One more question is a procal really needed going to 285/70r17 I did a search and found some say yes some say no.
go to 315s and regear to 4.88 in the spring. I went with 285 and love them for dd but definitely want that bigger and meaner look. I am running the 2.5 RK stock mod and get about 3 inch of lift. I will eventually go to a dana 44 front axle but thats another year and paycheck
- Auto, black leather, 730N, body colored top and flares, air, 4.10 axle ratio, max tow, dual top, connectivity, remote start
- Ordered 10/01/13, "D" status 10/14/13, "D1" status 11/01/13, "KZ" status 11/18/13
Split the difference and look at 305/70/17 (33.5~). Size falls right between 285/70/17 (32.8~) and 315/70/17 (34.5~) If you are not playing in the big "rocks" or deep "mud" then there is no need to go bigger except to fill up the wheel well.
I have been considering my options since last May when I purchased my unlimited Sahara. After reviewing this site for 100s of hours I have decided that my daily driver/weekend worried unlimited 2013 will receive the following upgrades:
1- 315 Tire
2- 17" Rim
3- 2.5" lift
4- 4.56 Gear
If I had something to tow like a heavy boat or trailer I would upgrade to a 4.88 ratio.
