37 inch tires on 18 inch wheels... Anyone???

[Sarge502]

I know the pros and cons of running a 17 inch wheel versus an 18, so I'm not really looking to be schooled on all that. I have specific reasons on why I'm on 18s and even looking to stay with 18s even when purchasing aftermarket wheels soon.

As standard the Overland comes on 18s. However I upgraded to 35s on the stock Overland wheel which hasn't been bad and look great on my current se up. However I'm looking to get aftermarket wheels soon and my tires are still practically brand new. Running Cooper Discoverer AT3 XLTs (35s). Not even close to the 60k mile warranty they offer and they've been great. So I'd like to stay with 18s versus buying new tires right away for whatever wheel I go with.

However I'm thinking in advanced, once it is time to renew the tires I'm exploring possibly going with 37s for a few reasons (although I've got to consider a regear thereafter but that's another story). One being I personally like the wheel to tire ratio of a 37 on 18. I actually think it's the sweet spot. I know some consider the 50 percent rule on tire/wheel ratio but I personally think 37s or anything higher on 17s is just too much meat for my personal liking. I may also just stay with 35s. Besides I actually like 18s. They are big enough to show off its detail yet allow room for tires and doesn't scream at you for attention like a 20.

I also know options are limited for tire choices especially in an 37inch AT. So I may switch to a MT to open up options slightly more if I do go this route. But I prefer an AT.

Just looking to maybe pick the brain of those running 37s on 18s on their tire choice and why but also their overall experience with that set up. Maybe also a visual of that set up.

Perfect. Love it.! That's exactly what I'm talking about. Perfect stance. That wheel to tire ratio in my opinion is spot on and is what I'm talking about.

35s on 18s aren't bad and I may stay that way but I really wanna go 37s in a perfect world. Not looking forward to regearing though.

Couple questions though. What's the width on those Grapplers x12.5 or x13.5 and that wheel width itself on the Black Rhinos? Also what lift you running to allow room? I'm considering the basic Mopar 2 inch and hoping that'll be enough clearance.

wheel width is 9”

tire width is 12.5”

suspension lift on this one is Mopar 2” with .75” spacer in front

Love those Black Rhino wheels - I've had them in my cart for a while now...?

35s on 18s as well. Planning to go to 37s when these are due for replacement in a year or two. Guess I didn't realize 18 was an odd wheel size?

Nice. I wouldnt say is an odd size overall. It just not as popular in the off road community. And tire options are more limited the larger you go on an 18.

Nice stance as well. Similar to mine already other than I want your Mopar lift. I'm on rubicon take offs with a front leveling kit. I may stay with 35s, who knows.

My Mojave I traded has a similar ride height as the Rubi. Opted not to do a spacer lift and to me, didn't really need one. I had a Sport S prior with the Mopar lift. (Yes, I'm on my 3rd Gladiator in less than 3 years.) Didn't realize how much higher it actually feels with the lift. Only reason I wouldn't have lifted a Rubi had I gone that direction would be cost. I put my money in the diesel, lift and front bumper/winch instead of the specialty of the Mojave or Rubi.

@Discount Tire thanks. The tires and wheels were all purchased at the Discount Tire in Pasadena, Texas.

I’m with you on the 18’s, gives it a much more “stock, utilitarian, overland, even modern look” vs a mud bog or rock crawler look imo.

Keep in mind 33” tires use to be big and 17” rims were a lot bigger deal. There’s plenty of meat on a 37” tire with an 18” wheel. If it works for your type of riding and you prefer the look I would run it.
