We took delivery our our new (to us) 2019 legacy 3121RL. I was happiest about all of the upgrades when I saw the Sailun tires. One thing I did not need to fix, repair or replace.

My Montana came with Goodyear Marathon tires. After three years of light use and maybe a couple thousand miles I got ready and took off on a Sunday afternoon on a holiday weekend. Boom ! one tire went and I had a spare so I Am all set. A couple hours later and Boom ! another tire and no spare so had road service come out with a new tire after a few hours of waiting I was on my way. Got to just south of Knoxville and Boom! a third tire all on the same side of my camper. I got it replaced and went back to the fellas shop bought a couple more tires for the other side while back at his shop. Good year Endurance tire is much stronger that the first tires and they are made in the USA. Higher speed rating (to 75 mph). I didn’t get my spare changed. yet but I will. Had the left side of my camper fixed and that took a couple months to get parts and such. I think they. are much better tires. I like the USA tires. I have a 3900FB

Goodyear

I don’t have mileage experience but when my 2 year old China bomb exploded on the high way to flagstaff in the mountains at night I rolled in the next morning and replaced all 4 with Goodyear endurance. The sidewalls were very stiff compared to any trailer tire I have seen in the past. Only a year and a half on them so far but only a couple thousand miles. Will update later when miles go up. These are E rated ST tires on a 2016 362RD.

I replaced my OEM tires (3 yrs old) with Goodyear Endurance ST235/85R16, one size bigger. They have an increased load capacity over the OEM tires and a better speed rating (87 MPH). The OEM speed rating was 65 MPH. I have 2 years and 10,000 miles on them. They hold pressure well as I've never had to add air to any of them. So far I'm extremely pleased with their performance. I also like that they are made in the US.

Goodyears that came on my Montana only lasted a short while before their tires failed. I believe they were Marathon tires. New Goodyear Endurance tires are made in the USA and a much better tire. Not real expensive but when compared to the original tires they are in a new league. Certainly like the USA built tires and so much stronger side walls.

I am hoping the Goodyear Endurance prove out to be a quality tire. I have a hard time with their weight rating for an E rated 16" tire, one of them is rated higher then the Goodyear G614 that is a G rated tire at 3750, which is 235/85/16. That same size in the Endurance is 3640 , but an E rated tire. The next size up is 255/85/16 is 4080 ,still E rated tire.

Over the years the G614 has had its issues, I like to buy a US made tire, but it won't be the G614. The Endurance have been out now about three years , lets hope they prove to be a better tire then their big brother .

There is a major size difference to consider when contemplating the use of the GY ST255/85R16 LRE tire. It is over 33 tall and requires a minimum rim width of 6.5".

The GY LT235/85R16 LRG does not provide the necessary load capacity for fitment on vehicle certified 7000# axles when complying with the RVIA 10% minimum load capacity reserve recommendation.

I'd get out of that dealer's store quickly...their tires are NOT 'N' rated. They don't know what they're talking about.

According to this GY Endurance chart they are all speed rated "N".

I am not sure I follow you on the Goodyear G614's you are saying they are not rated high enough for some of these Montana fifth wheels, they have been the choice of many for years.

If not mistaken some of the Montana fifth wheels at one time came with the Sailun S637's , and could upgrade to the Goodyear G614, IMO not an upgrade ,but they were more expensive.

Just for understanding, ISO doesn't set manufacturing standards. The manufacturer sets their own standards. ISO merely certifies that the manufacturer adheres to consistency that they set for themselves.

I don't like China making most of what we use. However, if they adhere to using quality materials, processes, and quality control, a desirable product can be successfully produced. Just because something is made in the USA doesn't mean it is high quality.

You are correct, they used to be an extra cost option on Montanas. Then RVIA (or somebody) moved the goal posts. No longer do the tires just have to exceed the axle rating, they have to exceed it by 10%. So a 7,000 lb. rated axle needs tire capacity of 7,700 / 2 lbs (i.e. each tire rated at 3850 lbs). The GY G614 is a Load Range 126 or 3748 lb. tire, just short of the 10% requirement. Hence the Sailuns became the standard.

My 2018 3731FL came with Sailuns and I had never heard of them. There was a GY option for $1800, didn't bite on that.

This past year I had what turned out to be a bent axel and it wore the inside off one tire. Didn't see it until it was really bad. got the axel replaced and put the spare on. The worn tire was showing steel belt on the inside but was still holding 110 lbs. The only drawback to Sailun is they are heavy as all get out because they are steel all around.

Thanks. Thats interesting. I am surprised , that kind of leaves the G614, and all but the one Endurance with a weight rating thats doesn't meet the ratings set for 7K axles.

If some remember at one time the Sailuns were an LT tire, and 3750, they changed to an ST, and increase in weight ratings.

I have seen recommendations of 5-7 years. I think there are a lot of variables that can come in to play. One of the biggest being exposure to sun. I just put on new Sailuns, I immediately bought tire cover for when it is stored or parked for long periods. After spending $700 I’m going to protect that investment.

I was hoping it was alignment so I could claim it on extended warranty but sadly it was clearly bent, plus I was in the third year so alignment should have shown up and it was only one tire. I'm thinking a bridge transition on the Interstate or nasty pot hole. I haven't been off road.
