Our trailer storage area was paved with asphalt. I always provided a protective barrier between the asphalt and tires. Here are a couple of pictures. One side required about two inches more height than the other because I had to park side to side on the drain slope.

Thanks Calvin. That link states not to store in greasy oily conditions which I interpret as a any surface where grease and mild has saturated the surface. The specific black top reference is in reference to heat absorption which I understand is a problem in hot climates but don't see that as an issue during the winter months. in all my reading I've yet to see a reference for how long in days, months, or years "storage" refers to.
I still haven't found the correlation between the black top and petroleum products. I know fully the composition of asphalt and I'm not talking about freshly laid blacktop, nor storing for years or during summer heat. I'm no tire engineer but "good old horse sense" tells me that parking on asphalt, over the winter, isn't going to inflict detrimental harm that will shorten the life or accelerate failure of the "aging out" life of an ST tire.
I'm not looking for an argument, just an understanding. Not trying to be thick headed but speaking information. So many times information can get misunderstood and even giant, worldwide companies will purport urban myth. Next time you fuel up look at the blacker on the pump about not using your cell phone while fueling. Then go try to find one confirmed case where a cell phone caused a fuel pump fire in the billions of refuelings that's occurred.
