Well you can run 37's with no problems, I would imagine that you wouldn't have any problems with 38's
Agreed. Looking at my rear clearance at full stuff, I think they’d just barely clear the sheet metal in the rear corners.

Ideal back spacing is factory, 6.25". Anything less than that is a compromise but more is always better if you can clear your tires. 3.5" is just super common and can be found in most wheels. Of course, they will help to clear my coilovers too.
Let me rephrase the question - sans the C/O clearance you need - what do you think the max BS would be and still clear with your lift height?

Max? Probably 5.5". That being said, you'll probably have an easier time finding wheels with 4.5"-5".

I have always been a Trail Grappler guy. Would the Ridge Grapplers hold up on the rocks?
Me too. Actually, I can't remember when I've last run anything other than a mud terrain tire on any of my play Jeeps. That being said, YES, they hold up great on the rocks or at least, from what I have seen. I have seen Mel from EVO put them through the paces and Dave from Synergy really punish them.

About a month ago, I started a thread/poll regarding 38" tires and asked what you all thought about them. I wanted to know if you would make the 1" jump when it came time to replace what you have now and according to the votes, the winner was in fact a YES! Albeit, by a small margin but more of you did say that you would make the jump but only if the manufacturer and/or model of the tire was something that you liked.

Well, I'm happy to announce that Nitto is finally giving you what you've been wanting, a Ridge Grappler in a 38x12.50R17. The 17" wheel size is important to note being that they already had a 38" available for a 20" wheel. That means this tire size is now available to most everyone and without having to get new wheels! And, as reluctant as I have been in the past to run a set of 38's, I am happy and eager to give them a try, especially being that they're made by Nitto.

Needless to say, ours just came in today and here's what they look like.

Love the nice deep voids especially being that this crossover tire is more of an all terrain than a mud terrain.

Of course, they still come with 2 different shoulder lug designs - their new aggressive lugs on the left and traditional block style on the right.

Which do you prefer?

Of course, these are going to be mounted on JET!

To be fair, the 37" Trail Grapplers on JET are worn down a bit but far from bald and they are mounted on a wheel. With that said, here are a few side by side shots of what the new 38's look like next to them.

Side shot to give you an idea of what they'll look like installed.

There's no denying it - the 38's are visibly bigger.

We're hoping to get these new Ridge Grapplers installed as soon as we can. The only thing holding us up is a new set of KMC beadlock wheels of which we ORDERED through Off Road Evolution and hope to pick up next week. So, it'll be soon.

And FULL DISCLOSURE - YES, our good friends at Nitto did send these to us free of charge. Nitto is a company that we've worked with for well over a decade and we're thrilled to help test and promote these new tires for them.

With that said, I'd love to hear what you think of these new 38" Ridge Grapplers! :cool:
So what is your opinion on going wider? I know the main 38" out there, Goodyear's are 13.50" wide over the regular 12.50" wide. What are your thoughts on that?

On the rocks, a 13.50 would be nice as it would allow you to have a wider footprint. I used to run 37x13.50 STT Pros and liked them a lot. For all around driving as in, a daily driver, narrower is better especially when it comes to fuel economy.

So daily driver, you prefer the 12.5, but for offroad, you'd go with the 13.5. I currently run the 40" x 12.50" x 17" STT Pros, but I have not been happy with the sidewall, I blew 2 of them. Regular tread was still pretty good so for the moment, I have 2 of them still no the front, but found some used Goodyear's with the Kevlar Sidewalls. But I am looking to upgrade to 42" (or 43") depending on what I can fit, and I am looking to move up to a 13.50 wide rather than stick with the 12.5. Also wondering if you do go to a 42 or 43" do you recommend going to a 20" rim? I really like the 17" Beadlocks you originally put on the jeep. See, I am now the proud owner of RubiCat that used to be yours :)

LOL - I thought the name sounded familiar.

So, for me personally, I prefer a 20" wheel with a 40" and would definitely want one with a 42" or bigger. Also, with a tire that big, I personally prefer a WIDER tire and one of my favorite setups on Moby was a 40x15.50R20. I should note that if you're still running the high pinion ProRock 60 rear axle that came on Rubicat, I would highly recommend replacing it with a low pinion.

Just flip the axle over - BOOM - low pinion! 😂

And, for those of you who've been asking, YES, the Trail Grappler in a 38x13.50R17 was released today as well :cool:
Do you know who will carry these tires? I'm looking everywhere already! HAHA
The weight difference of the Trail Grappler 38" vs the Ridge Grappler 38" will likely influence which one I'm buying. I'm ready as soon as I can find them! :cool:

I would contact Discount Tire here on the forum. Send him a PM and I'm sure he'll be able to help you out.

Thoughts on running these 38's on a stock set of Rubicon JL axles? Already on 37's but, well you know...
