Sailun 16" 637's

[Goin 4 Broke]

Ordered and received a set of the Sailuns from Simple Tire. Good price, fast delivery and fresh tires. Pulled the stock Goodyear Marathons and went to Pep Boy to have the tires swapped on my rims. Unfortunately they couldn't balance them - seems they didn't have the right wheel adapter. Hopefully their "master tech" will find an adapter tomorrow and they will be balanced.

Huge difference in weight and appearance. These tires are much more commercial than our wimpy stock Marathons.

I hope to report success in balancing and then road trip reviews this spring when we spend February and March in FL.

Let us know how it turns out. I would say there should be a big difference between the look and weight of good G rated tires verse the D and E rated tires.
Were you happy with the online price? I will feel a lot better when I have new quality tires on my unit. My 3160 is back at the dealer to try and get some more of the warranty work done. Some of my goals to have done before next year are new tires, inverter, satellite and electrical protection. For my work at home I still need to install the two Fantastic Fan Covers that I finally got from CW when our unit comes back from the dealer.

New to this forum...A week ago I ordered a 2016 Montana 3790RD with many options......One being the up-grade to the Goodyear G rated tires. I am hoping to have a reliable tire. I use TST pressure and temp sensors on my (for sale) 42 ft Raptor. Gives great peace of mind.

After we had a second blow out with the made in China Goodyear Marathons I purchased the S637 tires in October, 2013. We've logged about 5500 miles to date. One tire is wearing slightly more that the others but I believe it's due to the alignment. The overall rate of wear is very low maybe approaching 2/32 since new and the tires look like new. I've added air 3 times since they were installed. I could be my imagination but the trailer seems to handle better. I suppose it could be due to the stiffer side wall

I got my tires back from Pep Boys last night. Their master tech had to figure out how to remove the center hub dress up cap. Seems mine were a bit seized to the wheel.

They did the balancing however one wheel has like 6 wheel weights all in a row. Must be close to 8 oz. anyone else had a Sailun with this much balance weights?

Could be your "master tech" doesn't know how to balance a tire yet. My Sailun S637's were balanced with one small weight on 3 tires and none on the 4th. 3000 miles so far with no issues at all.

A good Tire Tech will remount a tire requiring that much weight by moving it at least a partial revolution on the rim and try again.
That just sounds like an awful lot of weight in one spot.

Just had four Sailun 235/85/R16's mounted on the 2012 Mountaineer. Had four Towmax which lasted about two years.
Uneven tire wear on the Towmax. Got the Sailun thru Big O tires. No problems getting them. As the tire tech said,
The 85's should have been on the trailer in the beginning, instead of 80's. The fifth wheel originally came with
Marathon's, they did not last. I am going to Mexico in January. By the time I return, I should have good idea of
how the Sailin's last.

After reading another thread on this forum I just realized another mistake! I did not have them install metal valve stems. I figured the stock rubber ones were like new. Now I hear that they can fail! What do all of you say? Should I pull the wheels again and have them dismounted, new valve stems bolted on and rebalanced? Or do I run them as they are and IF I experience valve stem leaks, then go the metal route? I do have a TPMS system...

Just for everyone's information, I happened to be searching info about the Sailun LT rated S637 tires, and came across this Sailun product sheet. It describes two different ST rated S637 tires, one an 80, and the other an 85. From what I've been reading, and due to an import tariff on LT tires, they have changed specs on their tires and now are calling their new ones ST tires. http://www.sailuntires.ca/MRT/S637.html

Looks like the only difference is .9 inches in diameter. I have heard guys state they were losing an inch between the tires with the 85. With the 80 now , which I think is the newer of the two sizes, there is no loss between tires ,and no gain in height .

Looks like you could pick either size. I would probably stay with the 85 .

Here is a link to a thread I started on rv.net after having the S637's installed today. http://www.rv.net/forum/index.cfm/fu...d/28646213.cfm I had 2 blowouts on the way home to TN from MD back in June with the Marathons that came on our 5er that was built in May 2012. the first was around mile marker 190 on Interstate 81 and the second at mile marker 17 which was almost home. Goodyear has sent me a check for the damages which was a little over $2,400 as well as $382 for two new tires which I was very happy with. The only hard part, other than working a lot of OT this summer, was getting the local dealer to send what was left of the old tires back to Goodyear for inspection. It finally took a call from Goodyear to get them to send them back. I priced the G614 from another Goodyear dealer and was quoted $325 per tire. I had the S637s installed today for $695 for four tires. We get a 10% discount from GCR Tire because of the company I work for. My 5er goes to the dealer for repairs in the near future so I doubt we will have anymore trips this year. I'll be sure to report back with any problems or lack of problems after some trips next year. One thing I noticed is that the link to Sailun's website referenced here is a Canadian website instead of the US website. The Canadian website has the 80 series tires shown and the US doesn't. There is also differences in the load rating and tread depth between the two websites. I posted the tables from US and Canada in the thread on rv.net. Anyway, I'm trying them and will let you know how they do.

RConkin, Thanks for your information and link. I will need to replace my tires before the next season, mainly just for peace of mind as they are still new. Unit is back at the shop and I do not see any other trips until springtime.

I've only ever had one leaky tire on my Montana, (I too use a monitoring system) and it was a METAL valve stem leaking. Take it for what it's worth I guess...

[jcurtis934]

If the stem is rated for the higher pressure, then it should work well without a sensor hanging on top...just my opinion. Think I would research metal stems that fit the hole size of the wheel, find the best, order them, and then have a tire shop change them out at some point. Only opinion that counts on this is yours.

Thanks for the advice. I will look to buy a set of metal valve stems. I will also carefully watch my TPMS

I think I just got a whopper of a deal. I bought 4 Sailun S637 LT235/85R16G out the door for $462 at NTB in Knoxville, Tn! I called this morning and was shocked at both the price and the fact they had 4 in stock. Now these are the LT and not the ST so they are older. I think the build date is 17th week of 2014 if I am reading the correct one, but at this price who cares! I called back and talked to a different guy to make sure they were looking up the correct tire. He said the price is $83.50 for the tire. I couldn't believe it. Our camper is getting warranty work done so when it is back home, I will get them mounted and balanced (the price already includes that). I will order a 5th for the spare also.

They may have been discounted just because of having them in stock for so long, I don't know. I just got off the phone with him while typing this and he said he has 80 in 2 different locations and can get it within 2 days. He said if the price goes up, he will adjust it what I paid today.

Guaranteed for 100,000 miles, 10 years or until you move the RV, which ever comes first.

So far I am very pleased with my tire choice of these Sailun's. Did the run from Chicago to Jacksonville, Fl without a hitch. Tires performed very well - held pressures with no adjustments. Tire temps were fine as would be expected in cold weather running down. I was usually running at 70 mph with occasional 75 to keep up with traffic. The confidence that I had tires that could easily manage the weight as well as run at 70 made the trip much easier this year.

While 1200 miles is not a convincing argument for these tires, yet, it is I hope the start of a long run with some serious tires at far better price than the Goodyears.

[MHC305RL]

I'm sure these will be better than the oem tires I have now. Even so we took a 5k mile trip last summer without a hitch, but I watched the pressures like a hawk.
