Ok - now the new Sailun question- what pressure is everyone running?
I know one person dropped from 110 to 100
Another post the Sailun tire pressure chart showing my High Country could go to 90 with my max weight
What say yee?

I se no reason not to run max pressure. Your tires will run cooler, get slightly better fuel mileage. Your camper will ride slightly rougher but you don’t ride in it.

I bought fresh 85 series instead of the 80 series. They were $10 each less than the 80. I run them at 100 and they run cool. At 110 it was a rougher ride. At 100 much smoother and still higher capacity than the 80.

I run mine at 110. Like mlh said you don't ride in the trailer anyway. I don't see how it is even possible to feel the difference in air pressure while towing anyway. Recently made a 2000 mile trip with some stuff on the counters, and it never moved.

110, not sure why you would run them at other than the recommended pressure.

It's not necessary to run them at max pressure if the RV weighs less than x. For example, at 110psi = 4,400lbs x 4 = 17,600lbs. Since most of our Montanas weigh much less than that at the axles, we can run less than max psi. The Sailun tire pressure chart goes down to 80psi.
Running less than max psi is done frequently by Class A drivers, after they get weighed, if their individual axles come in lower (and they can't stand the jarring at max psi). Having said all that, I run at 110psi because the FW seems to ride nicely and I've not had anything break loose inside.

From the manufacturer's website.....
http://gosailun.com/MRT/Tire/S637
http://gosailun.com/MRT/Tire/S637T
Looks like the S637 can be used on a motor driven vehicle AND trailers while the S637T is only suitable for trailers.

If you read the application it says that the S637t is for 5th wheel and trailers.

I just received an email coupon from simple tire for 10% that runs through the end of Jan. If you are ready to buy, this will save you a few bucks. Simple tire will ship the Sailuns to you if you don't have a local dealer.

From what I can see, Ply Rating and size availability.
My 347THT takes 235/80R16 which is only availble as S637T
I ordered 1 S637T tire (for the spare) from Tires-Easy.com for $137 with free shipping. It arrived very quickly, like 2 days.
If there's a better price, I'd like to know -- I need to buy the other 4 tires.
EDIT: That 10% discount (coupon code "JAN10") from Simple Tire is a better deal at $134 after discount. But after the discount expires, I think Tires-Easy has the better regular price.

How are the tires that come on the new Montana’s we just bought a new 2018 3120 with Sailun 235/85/16’s and I have had good luck with Carlisle’s brand but hope these new G rated tires will give me at least 5000-10000 before I have to replace them and hoping no issues if kept at max tire pressure?

I too had great success with Carlisle tires on lighter 5ers. The highest rating Carlisle makes is LR F. The Sailun LR G S637 are the best tire available, closely followed by GY G614.

Correct. They are rated for 4080# at 110# PSI. I would not run anything but Sailun on a 5er over 12,000# GVWR. I have the 235/85/16 on ~~ the only difference is they are rated at 4400# at 110PSI. Either are more than we need.

I paid 635.01 out the door for a set of four. Thats 158.75 each, bought locally.
After receiving them from Simpletire ,hauling them to a tire shop, paying for mounting ,balancing, probably new metal valve stems, you are going to be pretty close to what I paid. Around $25.00 total difference I would guess, not hardly worth the effort from Simpletire
Big O carries Sailun, I got a tire dealer closer to where I live here locally to match Big O's quote. Plus I knew before hand what the date code was on the tires. Plus Big O at the time was cheaper then Simpletire, so didn't have to see if they would meet or beat them .
So it appears Simpletire is a bit cheaper now, but not by much, probably because they were getting beat out by local tire dealers. Not enough savings to bother with Simpletire, unless Sailuns just aren't available locally.
I only say this because we keep hearing about Simpletire, they are not the only game in town, nor in reality the best price. Many local dealers will match the price, only need to ask.

I will not EVER run a Carlisle tire down the road. They came from the factory on my 2007 raptor toyhauler and were toast at less than 4k miles.I complained to the dealer and Carlisle, even sent a few back to be inspected. The dealer and Carlisle did NOTHING. You could not pay me to tow anything with them on it. If they were on my wheel barrel, I would have them replaced.!!!!!!
