PO'd Rv owner

Right now, I'm sitting here totally pissed off with Rv manufacturers. Last year while driving from the west coast to Toronto and back I had 2 major tire blowouts. This year, I'm planning on a longer trip. East. south, west and then north. So, I decided I needed 4 new tires for my Fifth wheel. I start my research online and talking with tire stores. I also check the forums here. I was a noob before I started this search. No longer. My Montana fifth wheel That max weight is 16,000lbs was delivered with Goodyear Marathon tires rated at 3000lbs. x 4 = 12,000lbs. So, this trailer was destined to fail. The blowouts were inevitable. Do these manufacturers not care one iota about the lives of the people who give them their money. I don't know how they can get away with this. I've only found two tires that would work on my trailer, both 14ply. Sailun and Samson. Sorry, rant over.

    Figuring 20 percent pin weight, each of your tires is carrying 3200 pounds.

    I also just put on the Sailun 235/80-16 tires for my 14k fiver. Each of them is rated at 4080 pounds at 110 psi. In your situation, I would suggest going with the 235/85-16 Sailuns if you have the clearance - they are .9 inch taller. They are rated at 4400 pounds each.

    The 85 series tires cost only a little more then the 80 series.

    * And I agree 100 percent with your rant.

    They don't give you much safety margin. Put the Sailun S637 G rated 235/80-16s on mine last week. Makes me feel a lot better with extra reserve capacity. They are a lot heavier and more substantial than the GY Marathon that blew out.
