Tires for my travel trailer

I have a 2008 Forest River Surveyor with a GVWR of 9411 lbs... It came to me with Good Year Marathons 225/75R15C on 15x6 rims rated for 2600lbs ea (this is stamped on the inside of the rim). The tire tread is almost 100% but sadly the dry rot is evident and they need replacement. I've read the good and the bad on Marathon tires, seems more bad than good in recent reviews. I'm leaning towards Maxxis tires, with that my question is... Can I go with the 225/75R15D 10 ply tires on these rims (which is what I'd like) or go with the 8 ply C rated tires?

Thanks

    Go with the Ds. You are correct in making sure your rims will handle the tire and the dealer should be able to tell you. My gut reaction is that it will be OK. Someone here will know.

    If those Marathons were original in 2008 then you got plenty of use out of them. As you know, the tread isn't the way to measure the life left in a trailer tire. I had a similar situation and changed over to Maxxi LRD and have been happy with them. My marathons came with the trailer and were showing signs of tread separation. Around 2008-2010 Goodyear was moving production around. First it was the USA then China and I think they might be back now but I haven't followed this lately. There were some bad tires out there but I don't think that is much of a concern now.

    Whatever tire you get make sure it has a safety margin with weight, keep them pumped up to the sidewall max and watch them closely. Get a tire pressure monitoring system if you can swing it.

    Thanks for the reply though I'm seeing a load range D 10 ply tire


    For Maxxis
    The 6 ply is a load range C at 1820 lbs.
    The 8 ply is a load range D at 2540 lbs.
    The 10 ply might actually be a load range D also at 2830 lbs.

    You could even go with 16's. If you do go that route you may want to take it to the tire shop you are dealing with and have them look at it and be sure you have enough room. It's on them if they are too close and dont fit. I ended up with enough room for my lever type tire chocks to still fit. I bought Firestone Transforce HT and the new wheels replaced the 15's that were starting to rust.

    Just remember, almost no one posts about their good experiences with tires, mostly just those who have had a bad experience. I've used both and don't prefer one over the other. They've both performed well for me.
