Tires

[Travelling Three]

I've been reading about folks replacing their ST235 80/R16 Trailer King tires with a Sailum tire which I would like to do also. I have a 2017 Montana 3661RL. I've read the the OEM Trailer King tire has a rating of 3,520 LB @ 80 psi. The Sailum has a rating of 4,400 LB @ 110 psi. My question is, what is the air pressure rating on my Montana rims? Something tells me it is 80 lb, why would Keystone put a larger capacity rim on any camper? Are the folks putting the Sailums on changing the rims out for 110 lb rims? Thanks for your thoughts, be safe out there. I'd go out and check my rims but its raining!

Our unit was ordered with Goodyear G614s and another on the lot just like ours, was not. Both had the same wheels as ours are rated for 110psi. The only way to know for sure is to take one of the wheels off and look at the back. Somewhere on the back should be a stamp stating the wheel's rating. That will let you know how they are rated. I run my GY @ 110psi all the time. The Sailuns on my partner's camper are ran that way too even though hers is a bit lighter than mine. There are inflation charts on the web that you can go by if you want them inflated for less pressure, but you have to weigh the unit to make sure you get the correct pressure.

I would bet my lunch money (and I love to eat) that your wheels are 110psi rated just as my 2012 models are. Take a flashlight and crawl under your unit and you should have 110 stamped on the inside of the wheels.

I spoke with the tire place for my Sailuns and asked what PSI is considered normal. We looked it up and he said, I should run them at 95 to 100 PSI. The 110 PSI is for maximum load. I haven't got my unit back yet, to see what they think is normal PSI. My concern would be getting those tires pumped up to that 110 level, it will probably take some time with portable compressors.

My 2016 with 7k axles has the 110 lb rims. I would be surprised if your did not have them. By the way I really am happy so far with the Sailun tires. One thing that I think is different with them is the trailer might ride a bit harsher as the sidewall is way stiffer. Can't really prove it but that is my opinion

Keystone says my 2014 HC rims can handle the 110 PSI. I climbed under and discovered not true. Shocking I know. The local tire dealer is researching rims for the Saliuns. Looking on line tough to find 6 bolt rims. Want to switch so will keep my fingers crossed.

My opinion is that the trailer also rides a bit harsher but now there is way less side to side rocking when towing as the sidewalls don't flex as much.

With the Sailuns and good metal valve stems you won't have a problem pumping up the tires because you will not have air loss like you probably do with the bombs.

I am confused, you said you have a 6 lug rim on you HC? I have a 2016 305RL and it is not a big one and it has the 8 lug rim and they are rated at 110 PSI, they are stamped on the back side of the rim on the spokes. Not sure what yours weights but am very surprised they would be 6 lug. Just curious

Yes, it is a six lug. I want to put the Saliun tires on but having a difficult time finding a rim with 6 lug that can handle that. I know strange. Emailed Tredit, who Keystone says told them the rims could. They say no. So it's confusing. I have tow-master tires and they seem okay but want to get them off. Weight on HC GVWR 12120 on sticker. May have to find a good 80PSI tire. Excepting suggestions.

Mike117: All you really need for your HC is a good LT tire. Duravis 250, Michlin XPS Ribs, etc. Their 3K rating, 75+ MPH speed rating and inherent reserve capacity are perfectly suited for a HC.

I have a HC and agree completely.

Goodyear has an American made RV tire called the Endurance

Thanks, I will look into the LT tire you mentioned.

[mlh]

A guy an the shop just bought a set of the endurance tires after much research. His camper has 15 inch tires and these were the best he could find.

I have the Mich. Ribs on mine as well and it gross's 144000. Have taken them on a couple of 4000 mile trips and is pretty nice to not really worry to much. They are spendy but worth it IMO.

[Mike117]

Okay tire people. My current tire is a 235/80/16. The Michelin XPS rib comes in 235/85/16 and 245/75. Will they 85 fit? Measured and have about three inches before it hits under carriage. This finding the right tire is a pain.

[Dam Worker]

You might have added extra 0. :-) 144,000 is over most semi truck weights.

I, as well as many others, use the 235/85/16 tires with no problems. And I have 93,000 miles on 2 sets and 2 trailers. I still have about 10,000 left, but must buy new as the axles wore the tread on the inside.

Your 2017 SHOULD come with Sailun G Range Tires. our 2017 has them. the 2017 Brochure in fact says "Montana is now standard with Sailun G-Range Tires...". Last page of this years brochure, under 'Travel with Confidence" heading. If you have something less on your unit, tell your dealer to put what Keystone advertises as "standard" on your unit. i would. false advertising...plus ours has them so why doesn't yours?
