launch edition on 35’s no lift

It’s a Warn mid height
Are you sure that is a Warn mid, the pics on quadratecs site show the mid coming to the middle of the headlight and the shorter one coming to the bottom of the headlights and yours looks like it comes more near the bottom than the middle?

do you have a leveling kit? Jeep seems to sit nose up and Gladiators come nose down stock?

thanks
No leveling kit. The picture does look funny but the ground isn't level, so maybe that's why.

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.
This is outdated information. New tires are designed to run higher pressures for fuel economy. Because of this the tread area holds its shape while running higher pressure or mounted on a narrower rim. I have 37x12.5r17 BFG KO2s on my LE with a 2 inch Mopar lift and I have not has a single incidence of tire rub and the Jeep has over 2600 miles on it now. Check out the link below to see that Discount Tire has a recommended wheel width of 7.5-11.5 for the 37x12.5.

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.

LOL, no not scared I run wide rims on my 12.5's but I did put a 325 on a narrow rim once and there was so much sidewall slop the Jeep drove like shit. Might have been a combination of that and the old Nitto tire I was running that were total garbage.

Other times I did it they were Ram 2500's and the weight of the truck wouldn't let you feel anything anyway.

Well if I ever have that uneven tire wear I'll get back to you. I have in excess of 40k miles on 35x12.5r18 Firestone Duratracs on factory sahara rims and they wore as even as any tire I have ever run. I already have 2600 miles on my LE and they drive excellent. So, given the information I just relayed of my personal experience, I would not be expecting that call very soon. And finally I will say that tires are given a "recommended wheel width" so that their section width is close to what they are advertising, not because a more narrow rim is dangerous or bad for the tire. Look at the chart you linked to and is says recommended NOT mandated.

Glad you are happy with your toys, there is an old expression. Steak tastes great but if you have never had lobster than steak will always be the best thing you ever ate. Forums are not about winning an argument, they are about helping others and sharing info. Take what you want from them and leave the info you don't want alone.

I have a set of BF 37x12.5's and they vibrate between 60 and 70 after being balanced on three machines and installed on two different set of rims. I have read many people complain of the same problem but yours drive great. My Goodyear MTR's are Kevlar and take barely any weight and are as smooth as can be. BF steak, MTR lobster, maybe they are both chicken in another mans World.

By the way did you know that the normal ins policy will only cover 5k in extras added to a Jeep in the event of a total loss? Ever had one burn to the ground? Ever been in a negligence lawsuit where some smart ass attorney found a truck was pulling a trailer that was too heavy for the GVWR of the truck and the party lost? Truck had the baddest ass Diesel engine that could pull down the twin towers but the chassis and frame weren't rated for it, but the truck could do it. Truck drove great, was so powerful but the negligent guy lost the case. Of Course companies use terms like suggested or recommended (even though I did not see where that word was used that you referred to) to avoid losing product liability lawsuits. Maybe you saw that word on the discount tire site, I didn't see it on the BF link.

I have owned and used many different brands of tires. Not the use of Firestone above. I am blessed that I can, for the most part, but whatever tires I want for my trucks. I had a set of MTR on my F350 that didn’t doo well at all pulling my forestry equipment. I had a set of KO mounted and they performed excellent. My loaded trailer weighed in excess of 25k lbs.

And as far as the scenarios inquired about above, I am 49 years old and as a former member of the forestry and agricultural industry, where guys are always testing the limits of their equipment, I have never ever heard of any case where some lawyer found out a “whatever” was used and they won a suit based on that information. I have, however, heard story after story and read warning after warning from various forum members throughout almost every topic imaginable that if you do this and there is a “whatever” you will be in court and you will lose and your life will be destroyed forever. But I have never personally seen it or even heard about anyone with first hand experience. If you can confirm that this scenario is common place please cite your source so that I can read up on it. In my new field we follow an evidence based approach to deal with various scenarios so I am willing to adapt. I just need an overwhelming amount of credible evidence before I change what has always worked for my in my personal and observed experience.

This is my rig and my former life.

Well that explains it, you are a Ford guy. I am a Ram guy. You like BF, I like MTR's. Rather be Cummin than Strokin as the expression goes. Laughing out Loud.

You seem like you like your toys, send your Gladiator to Dan McKeag and have him put in a 6.4 Hemi to turn those 37's and you will love that Jeep.

I am waiting to see if the diesel shows up or my LE would already be sitting in Dan's shop.

Have a great day!!

The link above is a very educational explanation of tire technology. If you read deep enough you will find that BMW and Chevrolet has sent cars out of their respective factories with tires mounted on rims outside of their “recommended width”. In a modern steel belted radial it is the steel belts that determine the tires overall diameter regardless of inflation pressures or rim width. The only thing that rim width can effect is section width.

I already love my Jeep. I don’t want a hemi in my Gladiator, to me it seems like a huge wast of money. My LE with the 37s will pull itself everywhere I have needed it to take me on the cruise control. I am not knocking guys who elect to add a hemi, it is their money not mine and they have different opinions and priorities than I do. I have plenty of toys that even some of my best friends think I’m crazy.

Can anybody tell me if 35x12.5R17 tires (Wildpeak A/T3W) mounted on the factory wheels will stick out beyond the fenders (Rubicon)?
