Heritage on 37's?

[Banshee77]

Hi, I know there has been many threads on tire sizes on different trims, just curious if anyone knows if you can replace the stock 35's with 37's on a completely stock heritage model, just not certain if the wider wheel openings and non modular bumper plays a factor on this.

I'm not against a mild lift but I feel like the stock sasquatch package it came with was fairly stout to start with and don't want to add any more height than what's necessary for mild off-roading in Ontario.

After owning it for a week a feel like a leveling kit might be a good idea regardless...

Also! Be sure to notice the giant rock chip in the windshield of my new Bronco! I mean it's basically a formal welcome to Bronco ownership I believe...lol

First, I'd ask yourself why you want 37's. If you're not off roading and need the (one inch) of clearance, you only have a modestly larger looking tire. Resist the urge to go big and save some money on updates to get it to work. You can go with a fuller 35 (my Maxxis Razr M/T's are a whole half inch taller than stock GY's! lol No changes needed tho, and they look great, they're also a lot wider) that gives the look but doesn't cost anything, or require stuff to be chopped off. Note that the stock GY's are physically smaller in width and height than a lot of other 35's.

The next thing to consider is going skinny: A 37x11.50 instead of 12.50 (or 13.50) will be lighter, cost less in gas, and fit better. You may not even need changes to fit, it just depends on the dimensions of the mounted tire. Only real downside here is not that many options. I think Nitto and Kenda do, both good tire companies. Maybe Mickey Thompson.

After that, you should be considering the JKS Max Tire kit (or the SFR crash bar mount delete) and yeah, probably a small lift like a leveling kit. You might go with a tire installed and then check out how it rubs (if it does), and correct as needed. Some find they don't need anything, some do. You might check out local off road shops that install tires, they can help you with this step.

Thanks for the info! The main reason I started considering the 37's is because a found a reasonable deal on a used set of 5 on nice aftermarket rims on marketplace, I thought they would be a nice upgrade for the summer months and put my stock setup back on during the winter months here.

Ok, yeah, if you want to buy them, you might find a shop that will help you test them for rubbing on full stuff and turning after they're installed and then have the shop make the updates as necessary. You could always just have the JKS Max Tire kit installed and do a leveling kit beforehand, and then do the rub tests (where you get the front full stuff and turn to check for rubbing). It really just depends on the tire.

I actually just purchased a 1" leveling kit because it was cheap but I wasn't in a hurry to install it until it was necessary, figured it would be more of a nuisance having to get the truck re aligned and headlights re aimed for no real practical gain

You might get the JKS Max Tire Kit already and just have it installed with the leveling kit, I think it's about $200US and installed maybe another $200-300US. They do cut stuff off, so you don't really go back once you do.

Some people worry about removing the crash bar mounts, since the crash crumple zones probably assume they're still there. But 37's typically rub on them, so they usually have to go, and I don't know you'd want to drive anywhere until it's done if they are rubbing. So if you're ok with it, I'd just do it.

JKS kit also comes with a front wheel well bracket delete on the rear of the well that the SFR doesn't, so it's more expensive but more comprehensive. Again, you may not need that but tough to know for sure.

Some people also have to trim some of the body panel and wheel well cover, but if it's done right, it looks fine. This is usually for even bigger tires but FYI. Each Bronco has it's own real dimensions, they're not all exactly the same even for the same model/trim/package.

I was curious if the heritage may be exempt from this due to the wider wheel well openings.

You can hit reply and it'll notify the person you're replying to.

You're probably right. I wouldn't assume it's needed, but it depends on what you're putting on, where the tire sits in the well, etc. What is the rim offset? You'd need at least +12 to 0 offset, above that and you're probably rubbing the UCA I think. (You can get spacers to fix it if it's too high, too.) If it's a really wide tire, it might catch the bottom of the wheel well (the body), but probably not. I just added that because it does sometimes happen.
