These new Salians call for 120 psi cold beer n the 235/85

Looks like they have changed the specs on the them . My Sailun ST235/85/16's call for 110 psi for max weight rating of 4400 lbs.

There is a bit of Apples and Oranges going on here. The "classic" Sailun 637 235/85/R16 is a Load Range G (14 ply) and has a max tire pressure of 110 P.S.I. My Vietnamese manufactured and my recently acquired Cambodian one (Date Code 2625) all have 110 max P.S.I..

Sailun also makes a 235/85/R16 Load Range H (16 ply) tire. Same numeric name but different tire. These tires have a 120 P.S.I. max

I see that now ,but what I don't see on their website is the G rate S637's . At least not on that part of their website . I'll have to look a bit further .

After looking more on the Sailun website , I am not seeing the G rated S637 , I am seeing both sizes 235/80/16 ,and 235/85/16 both H rated slightly higher weight ratings @ 120 psi . Can't find those G rated anywhere I looked on the Sailun website . I'm wondering if they fazed out the G rated in those two sizes , went to H rated .

I think you are right. The Sailun site only has the "H" rated. The original "G" tire are available at other retailers but mus be left over stock at this point.

That’s what I’m thinking , just whatever is left in stock . Looks like H rated on my next set next spring, mine will be 6 years old. Unless I go another brand , those Hankook look like a good tire . Don’t believe I’ve heard anything bad about them .

Well the DOT code is 05Y 216PLY and another code says 133/128M. Heck I may have got the wrong tire. If these are 16 ply are they going to be an issue?

My Wal Mart receipt says I purchased ST 235/85R16 132/127L G Trailer Tire. The Tire shows DOT code 05Y 215PLY and ST 235/85R16 133/128M. I guess this means I have a 16 ply tire? If so does it matter for a 34' Montana?

You had it right as far as the first post you made on the date code 2625 they were made in the 26th week of 2025 around early June of this year . No issues with what you bought , probably don’t want to run them 120 psi . I’d weigh your axles , and refer to an inflation chart for the proper air pressure. I’d think you could probably run them somewhere between 90-100 psi.

 

[PSFORD99]

You definitely got plenty of tire for your fifth wheel, I’m thinking yours is 15,500 GVWR ?

No sir it is 14,400.

I noticed when I pulled it home the trailer was a little more rough riding. I put the TST monitors on and it showed about 107 psi so yikes... I don't know who to call at Wal Mart...the local store can't help me

With that weight you can surely air them down a lot . You need to weigh your axles ,each tire individually ,and use the inflation chart for those tires , and go accordingly . But as said you got plenty of tire for that fifth wheel . Yes it would run a bit rough with those tires aired up . I run my G rated Sailun @ 95 psi. I don't want to tell you what you should run those tires at ,but just picking a number on my Sailun inflation chart for my 235/85/16's ,if my tires have 3200 lbs on ea. the inflation chart calls for 65 psi . My tires are rated for max weight of 4400 lbs. @ 110 psi , of course I am no where near that with my fifth wheel .

 

[PSFORD99]

Was that 107 lbs. cold ,or warmed up ?

I dont have a way to weigh each axel or tire. I will google the Sailun inflation chart

 

[PSFORD99]

Looking at my Sailun inflation chart , and dividing your GVWR of 14,400 by 4 thats 3600 per tire if you are loaded to your max GVWR , but as you know not all four tires will be the same . Going to my Sailun inflation chart 3640 lbs call for 80 psi , as said I don't really want tell you what to run ,but "IF" they were mine I would be running them @ 90-95 cold . That pretty much covers your GVWR if you were loaded to the max. Now your tires are rated a bit more being H's . I just can't help to think 90-95 is plenty . I would run them ,and see how warm they get ,and I would imagine warmed up they are going to be running up around 110 -115 but just guessing from what mine do running 95 cold . Also how the fifth wheel rides .

Do you think these are 14 ply H rated tires then or 16 ply H rated? I am not sure how to interpret the DOT marking I previously posted

 

[PSFORD99]

It's easy to tell there will either be 14 PR or 16 PR on the tire , easy to see , that meaning ply rating , along with a bunch of inflation , and weight ratings for single , and dual wheel application . They can't be a 14 ply H rating , H rating is 16 ply G rating is 14 ply . It's going be on the tire 14 or 16 PR
