You will not regret your decision after you pay the bill. Some have recouped some of their expense selling their slightly used RV tires on Craigs list or FB Marketplace. Seems farmers like them for their field trailers.

You can't always go by brand name when it comes to tires. About five to eight years ago Michelin went through a spell where their 22.5" tires were suffering from sidewall cracking...don't know about now. They were concerned enough, I'm sure due to the loss of revenue, to prepare a pamphlet with three pictures of cracked tires and trying to convince drivers two of the three were "OK" to drive and one showed a pic of one that should be replaced. Most RVers, ignored the pamphlet and spurred Toyo on to be one of the favorite 22.5" tires.

I would just like some clarification on tires. Are the 2022’s G-Rated? Also, the Rainiers that failed on a 2018, were they G-Rated. I thought 5 years ago they were still putting E rated tires on High Country. Just want everyone talking apples to apples. Also, if E-rated, make sure you check that you have wheels rated to 110 psi. We have had Goodyear G614’s and Sailun’s in the past. On our Alaska trip we had one Sailun slip a belt and two develop splits just above the bead. We replaced, with trepidation, with Discount Tire’s Hartland. I think my eyes were glued to my TST monitor for the next 5000 miles. We now have about 13,000 miles on them. So, it appears that there are more good options out there in G rated tires. You can get bad tires regardless of brand. Best of luck.

Ron, our 2018 came with Rainier F tires. Max PSI was 90. Our rims were still rated for 110psi.

I think 2022 going forward have g rated tires for mhc not sure what year they statrted puting them on. 2020 2021 was possilby been the earlest they went to g rated tires, 2018 where most likey e rated

Look at the manufacturer Daye stamp on tires. Alot of these companies like Keystone buy trailers full of tires and wheels and they sit for a year or two before ever being installed. You stated previous owner replaced but do same thing. I don't play the tire game ever. I've seen blow tires do 10s of thousands of dollars in damage in a few seconds. Sounds like you have doubts, then replace them. Never a cheap option but peace of mind can be priceless.

I did not see what tire load rating your current tires were. E, F, or G? That makes a big difference. I have a 2018 High Country that came with E rated tires. I had a de lamination that very fortunately for me I caught right as it happened and I was able to fix the damage myself, which wasn’t major. The tire stayed inflated and I limped to the next exit where I had the spare put on. Everything held up until I could get home. I bought the Salin tires and went to a G rated tire. I discovered another tire was starting to split and de laminate like the other one. Skipped the F rated tire which is what Montana High Country units now come with. If your rig came with E or F rated tires I would highly recommend you go at least to the next higher rated tire. They have stiffer side walls, roll better, have less side wall flex which helps them run cooler, and run them fully inflated to tire rated max. I have had my Sailins for 3 years and have about 3-4000 miles on them. Even tire wear and lots of tread left. Carlisle is also a great brand priced about the same price as Sailin. Just make sure you have plenty of load capacity in your tires. Happy trails!

As a tire shop owner/dealer and auto mechanic for 40 years I recommend and have installed both the Hercules and Carlisle Brand Tires and I'm 100% confident in either of those my recommendation is to upgrade at least one load rating and stay within the speed rating of the tire also make sure your camper is sitting level when fully loaded and connected to your truck as to not overload one axle set versus the other

I never had a failure on the Rainiers (2022 MHS 295RL) but, I also never had peace of mind. Lived with the Rainiers for one year, then changed to the Sailuns.

[BeckCass]

Was getting ready to say you should replace them but see that you have already reached that decision. Replaced our Raniers one trip too late.

[Moondragon]

We took a trip from NE TN this fall, on a circle tour of NC (Charlotte, Wilmington, OBX, Winston-Salem. TST TPMS installed since new. Tire pressure verified/adjusted before departure each leg. Halfway between Charlotte and Wilmington, the right rear blew taking fender skirt and part of the awning arm with it, total tread separation. No notice from TPMS, which was sheared off and was still reporting 103 pounds for the next hour. Replaced in Wilmington with a Carlisle LR-G (no Sailuns available there). On final leg from Winston to home, the left front went from 105 to 60 in 1/4 mile (TPMS worked!). Put the new spare on. As I arrived home, the left rear lost all air (TPMS worked again). All 3 were tread separation. Looked up Ranier tires, #1 complaint was tread sep. Bought 4 more Carlisles so they would all match. Bought additional sensors so the spare is also covered.

Put Sailum tires on your 5th wheel and grease all wheel bearings before your trip.

And what MorRyde fiasco was that?

3/8 tow out, so far have changed out all the rubber springs.

Buy a set of 14 ply Sailuns. When you remove the Rainers and compare them to a 14 ply tire, you will understand the difference and realize what a great decision you have made.

I always order my Sailun tires from Simple Tire. They will ship to your local installer. Just got a pair for $164.49 each. They always have good prices great service and quick shipping.

New Montana’s seem to come now with Sailun from factory.
At least ours did.
Just saying.

I believe that's true. I'm not sure about new High Country's though

Added: I just watched a presentation from the Montana Team of a new 2024 High Country and you could see Sailun tires. So...good news!

We have Ranier G-Rated tires on our 2022 MHC 373RD and have towed about 9100 miles on them since we bought it new in June 2022. We never tow more than 65 MPH. No problems at all. I have a TST-507 TPMS system and check the tires at every stop, plus check the actual temperature with a laser temp gun. When I do replace them, I will probably go with Goodyear. They were great on our last 5er we had.

[jsmitfl]

We have roughly 10,000 miles on our Hercules tires and no problems, I would drive cross country with them and back home. They are heavy but well worth it.
