FWIW, on page 7 of the Michelin RV Tire guide, under "Long Term Storage", they say "Place a barrier between the tire and the storage surface. Suitable barriers include plastic, plywood, cardboard, or rubber floor mats. "
My trailer always is parked at the exact same spot in my pole barn. The concrete floor had a sealer applied when new and now there are brown spots at each tire location. I believe that the preservative in the tires is slowly being absorbed by the concrete despite the sealer. I don't know if this has much of a negative effect on the tires, but my floor is getting uglier with each passing year.
Your mistake was not using the manufacturers "inflation tire charts" to set the pressure properly to prevent brown stains transfer to concrete.. although improper setting of the WD hitch might even have something to do with it.. :B
