    I have two problems that hopefully someone can help me with. I bought a used coleman westlake pu last year and it had decent tires on it. I traveled from Dallas Texas to Destin Florida earlier this summer and had significant tire wear. The tires are wearing on the inside and outside edges. Definite cupping on the tire edges. I was running the tires at 35psi, but i saw last night that it calls for 60 psi at the max load. So i think i have ruined a good set of tires by having them under inflated. Any thoughts?

    The tires are Duro XL ST185/80D-13 Load Range D
    I have read the post on this forum and realized that they are not the easiest tire to find replacements for. I have looked at Northern, Etrailer, Eastmarine, Richard Tire, and a few more with no success. The problem is finding the Load Range D. I have found some ST175/80D-13 Load Range D, and I have found the ST185/80D in a Load Range C, but I think I want the original tire size back on it. I know this question has been beat to death, but any additional thoughts?

    I actually misspoke, I have found the ST175/80D-13 Load Range C. I have not been able to find any ST185/80D-13. I think I am ok going with the 175's, but the Load range C has me concerned.

    The load range C tires can not carry the same load as the load range D tires.
    Check the side wall of the tire next to the Load Range X and see what kind of load the tire is rated for.
    The tire can only carry this weight at the max air pressure.
    The full weight of the camper is the sum of the capacity of the two tires and the tongue weight of the camper.
    I would suggest finding the load range D tires and make sure you air them up for the load.
    You might look at etrailerpart.com or Google Southwest WheelÂ’s. I have used them in the past.

    I Googled Carlisle and Duro and both make that size in Load Range D. You may have to search more or find a dealer who's willing to order them for you.

    As stated in the other post, if you go to a LR C rated tire, make sure you're not overloading it. If the PUP came with LR D rated tires, it likely needs those.

    Yes, you ruined a set of tires by running underinflated. RV tires are not at all like auto tires when it comes to inflation. Check the sidewall for the recommended inflation and run them at that level.
