I "think" the Endurance is made in USA. At least some folks have said that's why they bought them. I imagine Goodyear learned an expensive lesson when they moved the Marathon tire production to China.
I bought Carlisles from WalMart.com and they were delivered to my local store, mounted for free and balanced with no issue.

Can the alloy wheels on the Montana High Country handle the pressure (110 psi) for the Sailuns?

The ones on my 2020 HC 331RL are but you would need to check your specific wheels.

So, after reading through this thread I went to Mavis Tire to look at there selection of ST235/80R16 tires, and magic, they were all speed rated as (R) 106 mph with two of them carrying a (Y) 186 mph rating including the Carlisle Radial Trailer. I'm impressed, but I don't think the Ram is up to it.

This was the New Port Richey, FL store website.

I found my answer on etrailer, they say Since wheels will be able to withstand the psi rating of any of the tires that are meant to fit it you will need to look at the valve stem as that is the deciding factor. For 110 psi tire pressure you would need all steel valve stems.

That may be true BUT I would actually verify that by looking at the back of one of the wheels. You're kind of in the "outback" there in Silver City and you don't want a wheel (or 2) self destructing while you're traversing the "hinterlands". BTW, love the place and will never forget our little family scouting trip out of Silver City to Mogollon about 50 years ago. Extremely interesting.

Frank,

You might want to verify those speed ratings. I don't know of any ST tire that's rated 186MPH and if I remember correctly, none that are rated over either 87 or 91 MPH. I know that Carlisle Radial Trail HD tires are all rated 81MPH except for the three 16" tires which are rated at 75MPH. https://www.carlislebrandtires.com/o...dial-trail-hd/

As good as eTrailer is they can't seem to get straight on upgrading tires. If your ALLOY wheels are 6 lug I don't think they are rated for a tire over 80psi. eTrailer was referring to steel wheels in that link. I tried every which way to go to higher pressure tires when I had a HC with 6 lug wheels. I called the wheel manufacturer, Tredit I think, and talked to an engineer. She said the wheels would crack around the center.
Take the wheel off and look on the backside. You might have to do some interpreting to get the rating. It may say like: 8H3800 or 6H3240. 8H being a 8 hole wheel and a 3800 pound WEIGHT rating. (I'm pulling numbers out of the air) So you will need to see what load rating tire is 3800 pound weight rating. Or, it could just say 80psi or 110 psi etc.

This was the New Port Richey, FL store website.
NHTSA authorizes two ways for tire speed ratings to be displayed on your tires. The most popular is to find the tires load index; such as, 129/125 L and convert the speed letter "L" to it's rating, 75 MPH. A lot of ST tires have the speed rating written out on the sidewall. ST tires without an sidewall speed markings default to the TRA recommended 65 MPH.

For some reason I've never found the answer to, there is no speed letter for 65 MPH.

Interpretation, need to research and confirm the tire ratings for speed. Misinterpretation ... best example I'm aware of is this sign. Many folks think it's the minimum speed for the interstate.

We always enjoy the Gila area and Silver City's Little Toad Creek has great craft beer, particularly 'Pendejo Porter', look up the Spanish meaning...lol. We wanted to stop by recently but had to come home early instead, thank you CV19.

How stupid could I be thinking those were real speed ratings. Thank you all.

I am going to crawl under there tomorrow with a flashlight and see if I can find anything on the back side of the wheel, then I'll know for sure.

There is no regulation that requires wheel manufacturers to mold each tire with its individual specifications.

OEM wheel providers may request the wheel manufacturer to mold some specifications into the wheel. Sometimes that is twofold according to the wheel's number of lug mounting holes.

A standard answer form an OEM provider or trailer manufacturer is the wheel meets the requirement for the tires provide as Original Equipment.

Somewhere in the chain there is a letter of individual wheel specifications authenticity from ASE, they are tasked with certifying all our wheels. Finding out who has that letter is the key in finding individual specifications. The wheel manufacturer will have the original.
