Do most people get a 5th wheel and tire and do a 5 tire rotation, or get a 5th tire of the same diameter and mount it on the factory spare rim? I assume the spare rim has the same dimensions as the stock rims? I'm hoping to order my JT next month. I've even considered a narrow width 35 for a spare when I upgrade to 35s to increase ground clearance and lower costs.
There's a couple of threads and dozens of posts on that.
The steel wheel for the spare is 17". The Overland has 18" wheels.
I bought an Overland wheel from a guy who replaced the wheels on his truck and bought 5 matching tires.
There's almost as many opinions on that as there are JT owners.


Know for a fact (from Mopar Engineer), it was designed to hold UP TO 35 in stock location.
The true diameter varies with brand, width, etc. - and some have put larger tires under there.
One company's 35 may be 34.6" while another's may be 35.2" That's a fair amount of diameter difference.

That has also been discussed as it was asked multiple times and finally someone fit the largest tire they could up there and posted the size.

All jokes aside, I'm totally serious here, I was significantly inebriated about 2 months ago, and purchased a stop sign on amazon for this exact purpose.

It's sitting in my darn garage now as Ive been struggling to think of the best way to actually use it - considered running a hole saw through the middle to create a space for the spare winch to fit through, and bolting a 5x5 wheel spacer in the middle to reinforce it, but I would need a bracket or something to go between the stop sign and the hub of the spare tire or it would just crunch when you tried to crank the spare up into place.

I uhh.. spent way too much time and energy going down the rabbit hole on this one.. short of fabbing up something nutty, I think a stack of wheel spacers is the way but I've put it on the back burner..
A easier fix would be mount the tire the other way maybe? I haven't looked to see if it's possible but I bet it could be. Then at least you can check the air pressure without lowering the spare tire too.

I am running a 37x12.50r17 Patagonia with a Quadratec Recon wheel. The spare is stuffed up under the bed in the OEM location. There is about 3/4 of an inch of clearance between the tire and the track bar with the tire deflated to 16lbs.

The tire has been set down on stuff a few times, with no ill effects thus far.

stop signs have pointed edges and are made of thin aluminum... might not want it to bend and poke your spare.

RR crossing advanced warning signs on the other hand - those are round. Perfect circle. Minimum size for roads is a 36" diameter circle, though, so maybe a bit too big (but honestly I haven't peeked down there so perhaps it'll just cap everything off nicely).

W10-1 sign, 36" diameter though you can probably find 30" too. Save a few bucks and get it without reflective sheeting - https://www.hallsigns.com/36-circle-aluminum-sign-blank/

Old stop sign ?
This. Just get some 1/16" steel, cut it to length, cut a notch in it for the little block that holds the spare. Load the tire on said block, then followed by the plate. Rotate the block 90 degrees, and raise the tire. Done.

Ive seen old stop signs used in many ingenious ways. They are used a lot on 4 wheelers. I figured it would be close to perfect for protecting a spare. If not an actual stop sign, something similar or shaped better for the application shod be easy to fab up. If mounted correctly, I would think it would add a great deal of protection, being made of aluminum or not.
