Lift and Tire Advice

Well this is my first post and my first Wrangler, so I can use ALL the advice possible. I am wanting to do a lift and tire package. I am wanting to do the 2.5 AEV lift but I am torn between 295/70/17 and 305/70/17 tires.

I do have an automatic with the 3.21 gears and really don't have the money right this second to regear.

Any advice would be very appreciated. Thanks!

Your profile says you've got a 2013. If that's right, I wouldn't sweat the regear; not only is it not cost-effective for a 3.6L Jeep with 33" tires, it's probably not even necessary, even with an automatic trans.

I've got a '12 (same engine, but a manual) with 3.73 gears and 35" tires, and it's very close to being fine.

The only place you're gonna notice any power loss is on the highway, either trying to pass slower traffic, or going up hills, in high gear. And with 33" tires (most of which are really 32s), it's gonna be minimal.

My advice would be to forget the gear change, in your instance.

Sounds like a plan to me. The AEV has some of the best road manners of any lift out there, IMO.

However, I'd seriously consider going down in tire/wheel size, for the following reasons:

1. You'll save a ton of $$. In most instances, you can buy 15" wheels AND tires for the cost of 17" tires alone.

2. You'll save weight, which means the effect on your gearing will be even more minimized.

3. You'll end up with a fatter sidewall and a bigger contact patch, which you should find helpful in slick conditions, off-road, etc.

4. Did I mention you'll save a pile of $$?

That's a 33.8" tall tire, 12" wide. You won't have any issues, vertically, with a 2.5" lift. In fact, you could get by with something much cheaper, such as a TeraFlex leveling kit, if you wanted. But, if you plan on wheeling regularly, or adding a lotta weight in the form of bumpers, winch, skids, etc, you'd be better off just going with the full lift right outta the gate.

As far as the width of those tires, you'll need one of two things to avoid any rubbing:

Wheel spacers...that's if you're planning on keeping your stock wheels, which have awful backspacing.

OR

New wheels with ~ 4.5" of backspacing or less.

A regear costs +/– $1500; best bet, if you plan on regearing, is to settle on a tire size, first. If you decide to run 37s, regear for that, and then, later on, change your mind and go down to 33s for, say, mileage purposes, your Jeep will scream like a sportbike in high gear. Not good.

Thank you for your advice. I do have the 2013 Wrangler, 2 door, automatic. As soon as I finish typing this i will be looking online at different tire/wheel combos then what i had originally stated.

If you have any more advice please share.

Thanks again!

That's almost a 34" tire...my guess is you'll notice some power loss in high gear, trying to pass on the freeway or going up hills. Around town you won't notice much difference at all.

If you've got a manual it'll be more tolerable, since you can choose your shift points and simply skip 6th gear when needed. With an auto, you'll more than likely have to give up OD to avoid the hunt-and-peck of your tranny trying to find the optimum gear.

With the Pentastar engine, I don't think that tire/gearing combo would be horrible, but it's a very subjective thing. Some folks run 3.21 gears with 35" tires and have no problems with it; I run 3.73 gears with 35" tires and plan on regearing to 4.56 soon.

It all comes down to weight and rolling resistance. Sticking with the 17" size will hurt you; but a lot will also depend on the tire weight...if you're looking at Nittos, or something similarly heavy, the affect will be more noticeable.

Only thing you can do, really, is buy the tires you want, then drive the Jeep and see if it works for you.
