I’ve decided I’m going lift with 37’s on the LE rims. 37x11.5 MT’s. Should look about same proportions as this. Just a few inches taller.
Have you followed through with the 37"s on your stock wheels yet? did you require spacers?

No, I ended up with the 35" on the stock LE rims. Very happy with the setup. I've completely articulated the front end on trails with disconnected swaybar and no issues at all.

That is a 315/70/70 so its 12.7 wide. Its on a 7.5 wide stock LE wheel. Hope that helps.

How is the trail cam view with the bull bar attachment? could you post a pic of your screen view when you get time?

The LE comes with a 7.5 wide wheel. 35x12.50 tires have a min 8.5 wide rim rating but that does not mean that it will rub or can't be done. It means the tire will be forced on the rim and the flat part of the tire that touches the road will be curved instead of flat. I have done it many times on Power wagons, its not the safest mount since it is putting force on the sidewall and won't necessarily wear the tires in the middle. it all depends on how much air you put in them.

A 315x70x17 is a 34.4 tall and 12.4 wide so the tire is slightly shorter however not all tires are true to size anyway but mounting a 315 which calls for a 8 inch min wide rim on a LE 7.5 wide rim is better than mounting a 35 which calls for a 8.5 min rim on the LE 7.5

Like I said it can be done and I have done it more than once and had no issues. Before you pick a tire read the specs as there are 315's that are actually 12.7 wide and there are 35's that are only 34.4 tall.

A tall tire always looks better, a tall narrow tire does better in the snow but a wider tire will always cause less highway wander in the steering unless your front end is not maintained properly or you are on a very bad road that has ruts in it. As far as offroad it depends on the conditions you run in but these two tires are so close in size it won't make much of a difference. I personally would choose the tire that is closest to the wheel width it calls for.

A BF 35x12.5 is not a true 35 tall tire it is a 34.4 so might as well run a 315 which is manufactured to be on a 8 rim because you aren't getting the true height of the 35 anyway. A Goodyear Duratrac is the opposite, it is a true 35 tall tire, if you plan on changing wheels at any point any new wheel will be a min of 8.5 wide and then you can run anything safely.

Metric tires are a lot less expensive, FYI the LE 285 tire that they call a 33 is really 32.7 so going to a 315 which is 34.4 is almost two inches. Since most 35's true size are 34.4-34.8 they are closer to a 315 actual size than a true 35 which there are really only a few real true 35's.

If you can find a tire that is 11.5 wide then the 7.5 wheel is not an issue but they are very hard to come by.

Sorry this is so wordy I hope people are following what I mean.
Once again we are not talking about rub, there is plenty of clearance in Gladiator wheel wells and the difference of .2-.3 of an inch is not going to make any difference.

Below is a link to the BF site that says a 37x12.5 should be on a min 8.5 rim. If/when you have premature wear or a blowout of a sidewall and you want to claim warranty or have an accident and hurt someone the attorney and the manufacturer are going to be referring to the BF info since they are the manufacturer. Discount tire will wash their hands of it. Remember who is selling you the tire and who made it. Can it be done, yes of course. Are you going to belly the sidewall if you cram a 12.5 on a 7.5 rim, yes. All depends how safe you want to be and how long you want your tires to last and if you are interested in the best performance.

Thanks for posting all of this. Best info I've been able to find on this particular subject. Was a little concerned about putting a 12.5" on a 7.5" wheel and hadn't even considered the 315. Certainly didn't know the 315/70 would be cheaper and you are right, almost $20/tire for BFG KM3.

One thing I haven't seen discussed though, anyone have any issues running them aired down on the trail?

I just put these 35x12.50R18's BFG KO2'S A/T on. I was going to level but I love the way it sits as is.

Not a LE, but a Rubicon.

What is the offset on your wheels and when does it rub on 37s with no lift?

Yes, I went with 18's with a +1 offset. No issues and love the look.
