[milsutter]

Am taking delivery of a 2017 3970RD on Thursday and it has the Sailun G rated tires on it.

So are they ST or LT? Very confusing when reading the literature. Some info stays they can be used on trucks also.

They are ST, G rated, made in China tires

Does it maater? They are heavy, well made, and no reports of issues probaby due to being made by the one good tire company in china. If sold below value in u.s. then issue is unfair business practice against goodyear 614. John

Or could it be unfair business practice by Goodyear. The price for a Goodyear G614 is outrageous. IMO all you are doing paying that price for G614's is paying for insurance to repair damage to the RV. This has been well documented with G614's.

The Sailun S637 has an excellent track record, have yet to read an issue with them, unlike the G614 .

Many of these Goodyears are not having blowouts but are running over debre and then gradually leaking air out of there tires which cause the tires to run hot then fall apart.This can happen to any other tire including the sailuns. The goodyears had a problem in the past but seem to be a much better tire today but the sailuns are still a much better buy for the money. I have sailuns on my rv with about 13,000 miles on them and they have held up real well.

I finally found Sailuns and ordered four 235/85 s . They aren't on yet. Now I wonder what happens if I have a flat tire and try to put on the spare that came with camper which I assume is a 235/80 as that is what the four tires are. Should I replace with Sailuns 235/80. Instead ? Replacing these tires is one of the most confusing things I have ever been through !!!

[DQDick]

Whenever I change tires I change the spare also even if it never met the road. Its still an old tire and if it's OEM before they went to Sailuns it's not a good tire either.

[Dam Worker]

I ordered the exact same size as the OEM tires on mine. As stated I probably should have bought an extra for the spare. Use your spare tire even though the size is about an inch smaller there is no differential/gears to hurt anything. It will probably put a bit more of the load on the bigger tire but you should be ale to get to a repair center without to many worries.

Where are you finding the Sailun? No dealers have heard of them around here.

[hybridhauler]

I second what Dick said. When I installed the new set of tires on our 3750, I bought one for a spare as well. I also found a matching rim so they are all the same

Who sells Sailun tires in Houston tX?

[Mike117]

Dam Worker, I see your in Richland. I am in Ferndale-Bellingham. Where do you find these tires and who installs?

[kenneth e holman]

There is not anyone that sells sailun's in Houston that i know of. I bought mine from simple tire.com. You can order from them and have Discount- NTB or who ever mount them for you. I bought 235x85x16 tires for mine and have about 13,000 miles on them with no problems.There is a discount tire dealer on the Sam Houston toll road just east of hiway 59 north that has a large enough parking lot to pull your 5th wheel into.Take the 1st exit when you get on the toll road and u-turn at the light and he will be on your right. You can pull down to the last bay and they can install the tires you bring and drive out the back of the parking lot with no problem. I believe they charge 16.00 per tire to mount and balance.

[captain1]

Thanks for your input. What size is your Montana? Mine is model 2980 2008 model which we bought new in 2009. I will have to check my rims to see if they would fit the larger 235x85x16. Otherwise the smaller 235x80x16 should work. We've seen a lot of the U.S. in the past seven years.

[Dam Worker]

Mike117 I bought mine from a place in Michigan if I remember correctly. When researching where to buy them in the Pacific Northwest I did find three or four places around the Seattle area that supposedly sold them. I really did not want to pull the unit over there for tires so I naught mine online jacked the unit up on manual mode and removed all the tires and rims. Loaded new tires and old rims with Trail King tires in the back of my truck and had Costco mount and balance the new tires and reinstalled on the unit. Simple tire sells them although the tire size is just a bit bigger (taller) and I decided to go with exact same size so I bought mine from Michigan. I can't remember their name but they had good customer service and the correct size so I decided to buy from them. I will try to come up with their name as they sent me a t-shirt and new steel valve stems for free with my purchase of the tires. If yo do a search on Sailun you will find long thread that I started and it has the company's name.

A couple of things you should consider/check:
1. I am pretty sure your 2980 (one of the lighter Montanas) has 6K axles, and not 7K like the newer rigs. I believe the tire sticker on the driver's side near the propane compartment will show which axle you have. Otherwise, crawl under the rig and check the stamp on the axle itself.

2. Montana didn't offer 110 PSI capable wheels in 2009. All of them were 80 PSI. The Sailuns will work at 80 PSI but be careful not to overfill them.

3. The 235x85x16 tire v. the 235x80x16 is really not an issue. The difference in aspect ratio has a minor effect on the height of the tire. Either one will fit on your rig.

4. You have 6" wide rims on your 2980 just like every other Montana. Montana has used the same rim width forever and fitted them with E rated LT, E rated ST (Chinese junk), G rated Goodyear G614, and now Sailun G617 tires. So either Sailun or any other standard tire will fit.

You really don't need G rated tires for a 2980 with 6K axles. Pick one of the better rated LT E rated tires (Duravis 250 comes to mind) which are far superior to the LT type E rated tire you have. Many members here have used LT tires for years, even with 7K axles (and some have weighed their rig to ensure their weight isn't too much).

My model is an 2013 model 3402rl.I have 235x85x16 tires. If you have the 80 psi rims instead of the 110 psi rims then as per previous post you can still use the sailuns but only at 80 psi and still have a much better rating than the load range E tires. If you have the 6,000 pound axles then you might want to buy the michelin xps ribs. These are the best 10 ply tire on the market and weigh 62 pounds each as the 14 ply sailuns do. I've had both and weighed both and they are the same. The michelins are all steel including the sidewall - same as the sailuns.The weight capacity of the michelins is the same as any other load range E tire but twice as heavy. I don't know why they aren't rated a higher capacity than other tires but they are twice the weight of other load range E tires and you will be very impressed with them. If you are within the weight limit for load range E tires then Michelin is the way to go. You can get them at Discount Tire. Good-Luck.

My 2016 3440RL which I just got in August, and is shown to have been built in Jan '16 uses the Trail King tire still. Was pricing the G614's and wow.... $1500 for a set..... not right now that's for sure as Santa needs a new pair of shoes... Havent looked up the Sailun's yet but will do that, but again, this rig has about 2000 miles on it sofar and showing no wear, but in my previous 5th wheel, which didnt weigh as much, I had terrible tire issues, namely due to alignment of the axles.

[DQDick]

Wear usually isnt' the biggest problem with cheap tires on our size rigs. Speed damage (could have happened when the delivery driver got to the dealer in a hurry), holes and curbs (again can happen before the rig even gets to the dealer) and just poor quality control at the factory as well as other issues make them a crap shoot as to whether they last. If you can't afford better tires be sure to get a good tire monitor system and check the tires for bulges in the sidwalls and tred seperation on a regular basis and drive at or less than the speed rating on the side of the tires.

Ditto Dick's response.
