Sailun 16" 637's - Page 4 - Montana Owners Club

Dam Worker · 02-15-2016, 01:34 PM

The wife and I went to an RV show put on by La Mesa RV at the University of Phoenix Stadium in Glendale just for fun. While looking at the RV's I noticed a lot of the heavier ones had 17.5" rubber and that the Landmark and possibly the Big Country both built by Heartland had Sailun S 637's on the 16" rims. Tires looked heavy duty to me compared to what Keystone is putting on their units. These looked more like commercial type tires, very similar to the GY 617's. I hope I got the numbers correct. Rated for 4080 lbs single and 3640 in dual mode. I think they used to be built as a single only type tire and now are also able to be run in a dual type configuration.

This thread has been going a bit but thought I would add my .01. My dealer put on 4 Sailun S637's replacing the OEM E rated TK's on our 3440RL. After the short 75 mile trip home we have a couple of short shakedown trips planned for local destinations to see if we can expose any issues with the coach. We will put 1800 miles or so on a trip to Yellowstone in May. I think that will at least provide us with some ability to provide some feedback on the tires.

This is all good information, keep it coming. We've got a little over 40,000 on our 614's so far with a trip from Florida to New Mexico planned next week and then on to Kansas so we don't miss the tornado season. We'll be needing to replace them sometime in the next three years so I'll be following how the Sailun's do.

Goin 4 Broke · 02-17-2016, 01:53 PM

Dick that is an amazing amount of miles. I can only hope that these Sailuns do half as well. I will keep posting progress as I hopefully can log as many miles as you!

Was checking my tires in Savannah before starting the trip home and found concerning, significant wear on my junk off brand E rated tires. Did as much research as possible and opted for the Sailun 637s and metal stems since I really couldn't find documented failures. Paid twice what you're getting them for, MHC305RL, and were still almost half the price of Goodyears 614s. Thankful that GY is standing behind their product and paying for damage to the RV due to blowouts, but I prefer not to have the blowout. Made the trip home with Sailuns and a lot more confidence with no surprises. Seems like they've got a very good product and you've found an excellent price.

MHC305RL · 02-18-2016, 02:22 AM

I just hope we have no problems with them for years to come. We picked up our fiver April 10, 2015 with Trailer King (I believe) tires on it and drove from Tennessee to Yellowstone for over 4k miles and to the beach and several 2 to 3 hours trips without one problem. I never failed to check the pressure before leaving the house or leaving the campground. So I expect these G rated tires to never even sweat on my 13k pound fiver.

I couldn't believe the price until I was pulling away. I wanted to let everyone know (on another forum also), that live near Knoxville, to check it out.

Starmaster · 03-09-2016, 02:31 PM

I just thought I would provide some more feedback on the Sailun S637 tires. Last October at the National Rally in Goshen TreadIt had rally pricing on the Sailuns at $109 so I put a set on our 3160, even bought a spare. I also made sure they installed metal high pressure valve stems on the wheels when they mounted the tires.

We now have about 5000 miles on them with no problems at all. We wintered in Tucson for two months this year. Prior to heading back home, I checked the pressure and found that they had not lost any pressure at all. I'm running these at 100psi cold, on the trip home once they warmed up, the pressure was about 115psi.

It may be me, but it seems that the 5er is more stable with these tires than the original Trailer King tires, Overall, I'm very happy with the tires and have a lot more confidence towing now knowing that I don't have to worry about tire problems.

Dave it is good to hear that so far you are happy with your 637's. My guess is that they probably have a two to one weight over most of the tires that Keystone puts on our units. The ones I saw on the Landmarks looked to be very heavy duty. I would suspect that the 637's and GY's 614's both make our units handle better. Probably most noticeable in windy conditions and rough roads.

**DQDick** · 03-10-2016, 03:02 AM

We thought ours handled better, particularly in the wind, when we put the 614's on.

kozzy · 03-31-2016, 06:45 AM

will these tires fit on the stock rims that came with my Montana? Whats size are people getting the 235/80 R16 or the 85 R16?
The sailuns come in both, the 614 only come in the 85/R16

Bill.vannuys · 04-07-2016, 06:06 PM

I just purchased Sailun 637s and had them installed yesterday. The stock rims on my 2014 Montana met the pressure requirement (it is stamped on the back side of the rim). I purchased the 235/80 R16s. I paid $168.50 each that included mounting and balancing.

Dam Worker · 04-12-2016, 04:45 PM

Now that I am ready to move forward on buying a set of Sailun's for our 3160 I have another question. My current tires are ST235/80R16 Trailer King. How many people have got the Sailun 235/85R16 tires verse the 235/80/R16 tires? Only .9" difference between them in OD, all other measurements are the same. From the research I have done so far either size will work just fine. Adding to the overall hight of our unit would be my primary worry. Space between tires should still be fine but I am leaning towards the 235/85R16's.

I just put a set of Geo Star 14 ply trailer tires on. They are Comparable to the Sailuns, I got them at Les Schwab and most stores stock them. So pretty good chance of finding tires in the west anyway.
They are STIFF, the Trailer Kings are like rags next to them.
They are 235/85's too. They fit fine.

Tom, I had no problem at all changing from the /80/ to the /85/.

bdimmick · 04-15-2016, 09:18 AM

Has anyone dealt with the Samson tires,280 we have had 1 blow out and almost two more but caught it just in time, we have always had the Goodyear Marathons and they didn't last two year.

Dam Worker · 04-15-2016, 11:00 AM

Beverly I do not have any knowledge of the Samson brand tires, maybe someone else will speak up. I like the Sailun brand.

Well today I ended up buying the Sailun ST 235/80R16 LRG 14's from Trailer Tires and Wheels.

Scott helped me with the purchase and I should have them by the middle of next week. I could have went to the rainy side of the state and got them from the Big O tire dealers but I try to stay away from the nasty traffic over there.

I could have also gotten them from Simple Tire and in fact I almost did. I would have saved forty some dollars but I would have ended up with the ST 235/85R16's which from all reports would work just fine. They want 125.99 a tire plus shipping and FET. I really got good customer service from Scott at Trailer Tires and Wheels and he threw in the metal valve stems and a T-shirt for free. I am already nervous about overall fitth-wheel hight and this will save me from another 1/2" increase. I think I will be very happy with these tires. Now to see if I can sell some Trail King tires with very low mileage

Its just the opposite for me, I would welcome the extra height it would help level a bit. My truck a 3500 Ram sits pretty high in the back. Every little bit helps.

Dam Worker · 04-15-2016, 03:37 PM

Right now mine sits pretty level. The 1/2" in hight increase probably wouldn't make any difference for most of my driving. I guess I am just a bit paranoid on certain overpass and bridge heights. Near Portland I went under some pretty low ones with no problem. I need to measure while hooked up to my truck so I have a real number.

I'll be putting on my S637's next week. Thanks for everyone's feedback in this thread. Just decided to bite the bullet now so I would have one less thing weighing on my mind as we head west in June.
