So I tow a 10K lb trailer regularly with my '16, I need E rated tires with off-road capability. The problem I appear to be running into is the 8.0" wide stock PW rim. Every tire that I desire in a 35" requires a 8.5" wide wheel minimum. Such as the Toyo Open Country M/T. Is it never advisable to go outside the manufacturer specs and put a minimum 8.5" wide tire on a 8.0" rim? Safety/liability?

Does this mean I need to get new wheels? What else out there has a beadlock like the OEM power wagon wheels? I've found these:

3200 lb per wheel seems a little low. My tires would be rated for more weight than that. Is what I am looking for not possible?

1. Great off road 35"
2. Load range E with index preferred 124 or higher as the truck is ran maxed out on weight for most of its life.
3. Some sort of bead lock for airing down.
4. Slightly outboard wheel offset is OK, not too crazy though I hate wheels/tires that stick out of the fenders too far.

Don't get hung up on requiring a tire with higher load capacity...

The 2014 and beyond Power Wagons have a 6010 lb Rear Axle Capacity
The 2014 and beyond Power Wagons have a 6390 lb Rear Tire Capacity (with the Load range D OEM duratracs)

Load range E tires won't make it a better towing tire on it's own... but they do have sturdier sidewalls if you are concerned about off-road punctures...

D rated tires often carry the same load index as E rated tires.

Yes, I want the higher ply and sturdier side walls. My PW spends most of its life with payload maxed out so I would like the buffer.

I'm reading online that a lot of people say they run 12.5" wide tires on 8" rims (slightly narrower than manufactures minimum recommendation of 8.5" wide wheel) just fine. Thoughts?

I'd probably purchase those Toyo Open Country M/T 35x12.5R17 and run them on my stock PW wheels. So that is an (E) [10-ply rated] tire rated to 3638 lb per tire. Just concerned about that .5" narrower wheel.

There aren't more plys in E rated tires, they are literally the same ply construction as D rated tires. The C, D, E rating scheme is laughable and should be ignored.

12.5" tires on 8" tires is not a problem.

1. Stock PW wheels do not have a beadlock. They’re the same as any other wheel. They have a safety lip like any wheel.

2. Discount Tire ignores manufacturers spec and will install a 12.5” wide tire on an 8” wheel. They’re putting 37x12.5r17’s on my 8” wheels on Monday.


3. 3200-ish capacity is good

Bead"lock" probably isn't the right term for the OEM PW wheels, maybe bead retention? The bead seats seem more pronounced than other wheels.

The Hutchinson beadlock wheels are the answer in my mind. But get out your wallet lol.

As far as a 12.5” wide tire on an 8” wheel goes, there is absolutley no functional issue there. However, some name brand company’s will not mount them due to the manufactures rec’s. My local Discount Tire will not mount them because of that.

Ya the Hutchinsons are sexy. But I'd only gain .5" wider wheel for $2K. They are probably heavier than the OEM wheel too and harder to balance.

The stock PW wheels are just good quality wheels, but they aren’t special. The original wheels that were forged Alcoa’s are the unicorns but those were only made for the first few years.

Discount Tire has their own chart of tire/wheel mates that they follow.

The Hutchinson’s are unique in that they’re a double beadlock. They’re heavy but you don’t have to pay someone to change your tires anymore.

They would not mount 12.5” wide tires on my stock Rubicon wheels for me, I had to take the tires down the road elsewhere. Told me they wouldnt because the manufacturer recommends a minimum of an 8.5” wheel. I even offered to sign a waiver saying they would be off the hook, but that got me nowhere.

DamageWagon & Reloaderguy already told ya, PLY RATING and the LETTER have zero meaning these days. The Toyo Open Country MT 37x12.50 & 37.13.50 HAVE THE SAME CONSTRUCTION, and the same side wall, one is D rated, one is E-Rated, however, the difference is because the 13.50 has greater air volume.

You'll be fine with something like a 35x12.50R17 Toyo Open Country AT/II on the stock wheel for towing. I towed fulltime for a year on that tire, with zero problems.



That being said, those are E-rated and my 37's are D-Rated with a 124 load index. And still, the side of the tire lists the plys and there are 10 of them in the construction.

Focus on the load index, not the letter.

Ah a fellow Airstream/Power Wagon setup. I tow a 2016 Classic. PW and AS make a superb combo!

I have heard that the Toyo RT rides better and handles better than the AT2 in all scenarios. Interesting considering what they are both built for!

For sure! I haven't heard (or read) that yet.

A good friend is on his second set of 33" RTs on his Ram 1500. He got around 40k miles out of the 1st set with about 20k towing a heavy construction trailer. He swears by them.

I've heard the RT's are for people who seem to do mostly road miles. Very little feedback about how they do offroad. At least, that's how it seems from reading around. The MT/s don't seem to appreciate highway miles from my observations. But I drive a F*ton of miles.

Yeah I asked everybody I knew and a lot of guys I didn’t about the RT’s and nobody knew jack about how they really work Offroad or how survivable they are. I’ve heard some guys say they’re amazing in the wet, and a very good source say they were garbage in the wet. I think guys that really push their trucks don’t bother with the RT’s so there’s no feedback to be had

The rt’s on my lifted one ton van see a shit load of highway + towing and dirt. It’s a great tire all around, does well on road and very stable when loaded heavy or towing. Wet pavement traction is great, I can’t comment on snow or ice. Offroad they are remarkable in hardpack,gravel, and dirt/sand and rocky terrain. Slippery mud they aren’t great but will clear the tread with enough wheel spin. Would be lame for lots of mud or rock crawling, great for a daily driver that sees sand and dirt but not a lot of mud.

I’ve gouged the ring of one of my trailreadys and put my sidewall into a sharp rock trying to make it up my driveway in heavy rain because the rt was fishtailing all over the place. The tire handled the rock just fine but I barely made it up. Seems tough, just not good for mud.

That Maxxis Razr MT caught my eye for the simple fact that it’s a mud terrain with a 40k tread warranty. May not mean squat but caught my interest for consideration when my Toyo MTs where out.
