question on XPS Ribs

[4x4FF]

Next year my wife and I intend to start full-timing. I plan on installing new tires on my 5th wheel at that time. As I read the posts on here I understand the value of good tires. Michelin XPS Ribs are highly recommended on here...but....as I look at their literature I am a little confused. The size I would need is a LT235/85R16. I currently have 7k axles on my rig and when weighed have right at 11,500 on the 5th wheel axles. As I load the coach with more stuff this will probably increase some. Based on Michelin data each tire (XPS Ribs) have a load rating of 3,042 lbs. per hub. This gives me 6,084 per axle or 12,168 total. If I put the ribs on I am 'almost' at my max rating. With that being said, I also understand the difference between LT and ST tires and know ST tires are 'Rated' higher. Am I missing something here or am I calculating this wrong??

Around here Big O sells the Sailun tire. I ordered mine from online and had them mounted and balanced at a small tire shop in town. I took them off the 5th wheel myself and saved some dough.

Been looking through their website myself. AFAIK, the only dealers shown are Canadian. Cannot, at least until now, locate a US dealership.

Hope someone comes along that can assist.

I typed in "Sailun Tire Dealers" on my homepage and they have dealerships all over the United States...I found one that sells them within 20 miles of my home.

I got 11800 lb on my FW axle and I don't have any problem in the last 3-4 years with RIB.I use G614 before and I have to many problem with them.I think now Goodyear strait their sh... UP.

You've gotten away with probably overloading a tire or two, but please don't advise other people to do the same. Unless of course you've weighed each tire/wheel independently and can verify that your trailer weighs exactly the same on all 4 wheels.

Why do you think they put a weight rating on tires in the first place?

I have a 2006 Carriage 5th wheel. Fully loaded on a trip at a scale it weighs a fraction over 14,700lbs. Out of that the fraction over and 3100lbs is hitch weight. So I have 11,600lbs on the tires. I have been using the XP Rib for almost the whole time I have had the trailer. I bought it new. It had the Towmax china tires on it from the factory and they lasted for 7000 miles of towing . As soon as one showed signs of going bad I replaced all five with the XP Rib.I am on my 2nd set now. I replace them every 5 years by the date on the side of the tire. I have never had a problem out of them.The side wall also has a steel belt. They are heavy if you try to pick one up.
You did not mention your hitch weight in your 1st post. Is that included in what you posted. If so, you have less weight on the tires

I agree with above. I have XPS Ribs on mine and love them, but at a lower weight. I think you need to look at other options if you are going with LTs.

Yep, too heavy for the RIBS, but I'd also looked at G rated GY G614's and the Sailun tires...Keep an eye on the Carlisles, make sure you know what they speed rated to..

If you have 7,000# rated axles, then I would recommend that you go with G rated tires. The post that me again made with recommendation of G G614's or the Sailun tires are pretty much the two I would look at if 5er' really has 7000# rated axles.

And if GY G614 are to steep for you look at the Sailun LRG. It is similar in diameter to the 235 Rib, so you need at least 33" center to center on your axles.

G rated would be a better choice and provide an extra margin of safety.
