Upgrading to H Rated Sailun Tires on 16" Rims: Is It Safe or Worthwhile?

[20TwoAdv]

Why are you not happy with the G tires of Sailun ? I’m upgrading to H also but the G have been solid for 5 years . Sounds like a good plan to run 95-100psi .

Moving up to the H mostly due to matching what the factory started doing on our Montana in ‘25. Our ‘24 came with 16” G’s. The ‘25s and ‘26s now come with 17.5 H’s. Truthfully not necessarily unhappy with what we had but figured Montana would not upgrade without a good reason. I never felt like we had a good enough weight capacity safety margin with the 16 Gs. Now no issue for certain.

I thought I read that Sailun stopped making G tires?!?!

Have not heard that.

I read the same. They replaced the G rated with H rated tires. I have not verified it though.

Most web sites now list them as H rated . I think Walmart still has some G's . My concern now would be if you find some G's they are going to be an older tire in stock . I believe if you look on the Sailun website ,there is no G's listed for the ST 235/80/16 or the 85's . I am going to double check ,but I think I looked before when I started hearing about the H's .

Just went to their website ,there is no longer a G rated listed for the ST235/80/16 or the 85's . Only H rated , they bumped up the weight rating slightly not a lot , and went to 120 psi. There you have it , no more G's unless you find some still in stock with the vendors that sell them .

I am overly glad that I found this thread. After 2 blow outs on our 300 mile trip to breax bridge I’ve been apprehensive about traveling. We bought our MHC last year. We put less than a thousand miles on the Rainier tires that came with it. Adding the transport miles from the manufacturer they should not have had over 2k miles total. Vowing to never have this issue again we’ve upgraded to Sailun H rated 120psi tires (4540 weight capacity)which seem to have a great rep. Since the factories wheel and tires only rated up to 4080 110 psi on the G rated, I also upgraded the wheels to the Valhalla taskmaster Viking wheels with a 4450 weight capacity. I’ve seen some talk about the wheels being 90 pounds less than the tires but Sailun has an air down chart. We should be good I’m hoping at 110psi. Having one blowout you can deal with but 2 on one trip is something different. When replacing we found a third tire with belts coming through tire wall. Treddit reimbursed all three tires - with no argument?!! I also see that the manufacturer have now gone to H rated tires on the same model on this years model . I wonder why??????
Rv always kept in covered storage , aired and maintained before every trip going and coming.

Seems everyone here is having good returns with going up to H. I feel better now about the decision to do it.

I put the H-rated on my 2022 MHC 295. The rims are rated for 4180, I didn't see a stamp for max pressure - close enough. Have 8000 miles so far, usually run cold 115 PSI

Makes me feel much better about my decision to do This after 2 blow outs. Thanks.

If you inflated an H rated tire and G rated tire to the same PSI and they are the same size the carry capacity will be the same. The limiting factor factor is your 110 pound wheels.

I have a 2017 3661rl Montana. Replacing the current Sailun 235/80/R16 G rated 14 ply at 110 psi max air pressure with the Sailun 235/80/R16 H rated 16 ply at 120 psi max air pressure. The rims on my rig are stamped 110 on inside of rim. Should I worry about using the H rated Sailun or find some G rated Sailun to put on. Thanks in advance

Thanks for starting this thread. I needed to see others with the same thoughts on this issue.

Consider that if a tire on one side blows, the other tire has now been subjected to nearly twice it's load rating. Also, both tires are of the same age/quality of manufacture. It is very likely that the remaining over-stressed tire will also blow in very short order. That is why we upgraded to Sailun G's on our 295 and why we carry two spares: if one blows we swap out both tires on that side. Yes - this has been our experience more than twice.

Yea i changed wheels from 4080 to 4450 capacity. The wheels are 90 pound difference from tires 4540 capacity. Not too concerned. At 110, the H rated are rated at more than the g rated at 110 according to Sailuns inflation chart. Also went from 235/80/16 to 235/85/16. Thus the bump in capacity.

Going the front passenger blew and coming back the rear driver blew. When swapping over new wheels and H rated Sailuns we noticed the passenger rear side was slipping belts. That for sure would explain why that was possibly happening. Thanks.

Just purchased four H rated frim
Walmart but they still had Gs as well. My set were manufactured 32 25.

Following I am do for new tire in spring. If new heels are needed that is fine also. I would like to go to a heavier rated tire also.

Don’t really know if the G’s would have been okay or not, but since we were upgrading so many things we just took Montana’s lead in what they started installing on the 25 and up models. We are running 100 psi (using the Sailun loading chart I think we could go to 95 but not rushing that chance) and so far very happy.

Same here running my H rated Sailuns at 100 psi , do not need the 120 for my weight . Would be okay at 90 , but feel better running them a bit higher .

 

[Cdubue1]

Been on a couple trips so far with our new Gs. We air up to 105. I’ve noticed that they of course generate more heat at 100. Less at 105. So we’ve stayed at 105 because the psi never gets over about 117. For every 10 degrees in temp change you’ll see about 1or 2 psi increase. Totally normal. I’m getting more comfortable with towing again after 2 blow outs on the same trip. I believe this is the best combo for us as well.

 

[20TwoAdv]

Seems like some who switch to
The H are running 95-100psi and happy . What have you found ? I’m making the change in a couple months . TY

We’ve been running 100 psi. Considering going down to 95psi. 15600 lb with 2900 hitch wt.

Next time I buy tires, I will replace my G rated with H rated and run them at 110. Can't see a down side.

A great lesson many of us learned from attending a Montana Rally is getting your 5th wheel trailer and truck professionally weighed. One of the recommendations from the service is what pressure to set your trailer and truck tires based upon each axle and pin weight data. The outcome is a better ride and better tire wear.
