Sailun Tires

[69Roadrunner]

I have a 2018 Montana 305RL HC and I want to replace my Rainier tires, 12 ply. My camper weighs 10600 empty. I like what I’m hearing about the Sailuns, but as I understand it they only offer 14 ply. Is this overkill for a camper of this size, would the ride be too harsh? Thanks

[Mtncrash1]

My 345rl loaded and ready to travel comes in at 12500. I put the sailuns on earlier this year and, really haven’t noticed a difference in the ride.

[Daryles]

Be aware, the sailing run at 110psi. Check the pressure rating of your rims. There is a stamp on the inside of the rim for their max pressure rating.

[Theunz]

You don’t need to run the tires at their maximum pressure. The Sailun web site has a chart for what pressure to run at different load weights.

My preference has always been to have the best possible tires on my rigs, Sailuns have a smooth tread design unlike LT tires and I have never noticed a harsh ride.

If your tires are 12 ply rated, they are LRF and provide 3750# of load capacity at 95 PSI. Your axles are 6000#. Just how much load capacity reserves to you think you need?

For the factory to fit LRF tires they were required to use wheels with a PSI value equal to the maximum load of the tires.

Go with the Sailuns you won't be sorry.

[suny07]

have them on our 305 as well.

Thanks to everyone for your quick reply. To be clear, I’m not looking for more load capacity (camper has 6k axles) I want tires that are reliable. Since I don’t know of a 12 ply that meets that standard, the Sailuns seem to be the answer.

If your rims have a 110 psi rating, buy the Sailuns. Wait until you see the difference.

My MHC came with Raniers; didn't leave the lot until I had LRG Sailuns replacing the LRF Raniers - just because.....

[mhs4771]

Sourdough, very good choice and wise decision. Good friends went through all 5 Raniers in a short period on a new Jayco.

[Creeker]

Roadrunner - Do you know how many miles you have on your Raniers? Have any uneven wear? Any signs of bulging or tread separation? Anything at all by looking at them that gives you reason to want to change them? Previous flats or slow leaks?

The reason I ask these questions is we have the same tires on our '19 310RE. It is the sibling to your 305RL. Practically the same length and weight.

We have two seasons and around 9000 miles on our tires. They still look like new. I removed our spare just a few weeks ago and compared it to the tires in use. If not for the little nipple thingies still on the spare, I could tell no difference at all in tread depth or appearance in any way between them. They hold air when in storage as well as any tire I've owned on a trailer. They simply look in excellent shape.

Yet with this first hand experience, I still don't trust them based on my past experience with other Chinese made ST tires.

[69Roadrunner]

Tires have approximately 4.5K miles. They look good, showing some wear in the center. I don’t trust them, going to replace in the spring. I’d rather be proactive than reactive.

After the first year and a china bomb blowout I put the Sailuns on my 318RE. I run the pressure at 95PSI. The tires have performed great.

I did the same thing Danny did....bought a new MHC331RL and immediately removed the Raniers and replaced them with Sailuns.

I looked, but couldn’t find that information. Where is it located?.

IMO You would be so far over the needs of your trailer's axles with Sailun's they may jar rivets from the trailer at any PSI setting.

However, here's the procedure. Replacement tires MUST provide a load capacity equal to what the OE tires provided at their recommended cold inflation pressures shown on the vehicle certification label.

If using the Sailun ST235/80R16 LRG, I'd set their recommended cold inflation pressures at 70 PSI. That provides your GAWR axles with more than 25% in load capacity reserves.

don't understand..shopping tires so i took the Rainier info off the tires as such

st 235/80R16
load=F

tread: 2-steel --3 poly--1 nylon
sidewall: 3 -poly

doesn't that mean a total of 9 ply

[rohrmann]

The tire is 3 ply polyester, and it's just the tread area that has the belts that have the steel, poly, and nylon. With the Sailuns, there is nothing but steel in the entire tire.
