Sailun 235/80(85) R16 Tires, how do you like them?
I’m planning on purchasing new tires for my Cedar Creek 34RLSA fifth wheel with a 14,500 pound GVW. Sailune tire looks good to me. Are any of you already using them? What do you think. Not sure if I’m going to choose to 80 or 85 size again looking for advice.

They are a good tire. I replaced my Goodyear G614 with the Sailun S637 tires. This is my second fifth wheel to have had them installed.

there is a load capacity difference between the 80 and 85 size tires. what tires and size do you currently have. why not get the same size as your current tires?

Sailun tires
From what I have been able to research, there is not too much difference between the 80 and the 85s. The three things that I am aware of are the depth of tread which is 2 mm (10mm v 12mm) deeper on the 85 and the load capacity on the 85’s is 320 pounds higher. That also makes the diameter of the tire slightly larger. I think the 80 is 30.8” in diameter and the 85’s are 31.7” in diameter. Also the 85s carry slightly heavier load.
My current tire size is: ST 235/80R16 and measures roughly 30” in diameter. With the current tires that I have on, the space between the tires is 5 inches. If I put on the 85s, the space between the tires will go down to 3 1/4 inches, With the 80s it will be about 4 inches. It seems OK to me do use the 85s, but I’m not sure if that puts the wheels too close together. I like the additional load capacity of the 85s.
Sailune‘s website rates the 80 at 4080 pounds and the 85 at 4400 on a single axle. On a duel axle the 80s are rated at 3640 pounds in the 85s are 3860 pounds. I’m not sure if the duel means a double axle or four tires on a single axle.

Sailun tires are very good just put on my 2nd set. Cardinal 5er.
The only problem I had was I guess I had them underinflated,(80 PSI) so the outside wore first, I will be running them 95 PSI and see how they go, I still ran them for a good 3 years, Mine were made in Vietnam this time not China not sure what that means.?

On my third year with the Sailun tires. Highly recommend. Run numerous trips during the summer season and go to Florida from NY in the winter.
Use around 100 to 102psi cold, this turns into 110 to 112 when driving. There will be plenty of tread remaining when they age out in a couple of years. They are heavy tires and work great with my 14000 pound 5er. Hardly ever require added air which is monitored with TST.

Sailing 637
Excellent tire. We have put about 6K on ours. They took very little weight to balance. Very solid towing 14k in weight, 5 th wheel. Replaced Lionheads, the sidewalls on these are stiffer.

Where have to been, under a rock? Sailuns have been the goto for heavy FWs for several years now. However, we have started seeing some reports of failures with Sailuns made in Vietnam (rather than China) this past year. Do a search on "Sailun" on this and other sites, and you will be reading for days.

Are all new Sailun tires from Vietnam now. Mine are from China but are at least 3 years old. What's the deal on the new ones.

The major factor for going from ST235/80R16 tires to ST235/85R16 tires is the misapplication factor. The 85s are a larger tire. When such a change is made, the industry calls it "plus sizing". There are procedures to follow to keep your trailer's specs consistent when plus sized tires are installed in place of the OE size.

I follow tire threads closely on this and other sites. This past December I started seeing threads on multiple Sailun failures, where in the past five years, I recall only two reported failures. The recent failures all have one thing in common, which is they're made in Vietnam vice China. I don't know what it really means, and in any event, everything we post about tires is anecdotal as no entity tests ST tires.

Sailun S637s have been great for the past two years.
I’ve heard some issues with the there car tires but not the S637 ST tires.

Anybody running the Vietnam version? How are they doing? Are they as heavy as the China version? Seems like some are hearing stories about the new version.

Well don’t leave us hanging.
What is/are the procedures for plus sizing?

So called plus sizing refers to up sizing a cars tire size to achieve a different handling. Upping the tires on a trailer one size, allowing for sufficient clearance, will not truly cause any adverse handling problems.

I've found that there is no way to address plus sizing RV trailer tires without getting replies about my competence on the subject. Most consumers are not familiar enough with the differences in procedures between RV trailer tires and automotive tires when it comes to plus sizing. The quote below is an industry wide guidance for plus sizing. If you have your trailer's complete owner's manual you will find it there as it has been mandated by NHTSA to be there.
Always refer to and follow the vehicle manufacturer's replacement tire recommendations.

It appears to me the Sailun site lists load capacity for the S637T HD ST Trailer tire sized ST235/85R16 as 4400 lb if mounted as a single tire on either end of any number of axles and 3860 lb if dual tires (AKA "duallys") are mounted on either end of any number of axles. The weight capacity for the size ST235/80R16 is listed as 4080 lb for single mount and 3640 lb for dual mount applications.

I switched to Sailun ST235/85R16 on my 5er nearly five years ago, and I doubt you can buy a better tire for a heavy 5er without going to commercial wheel sizes.
