Quetion re: pad for tires on concrete

Michelin Tire on there website for "Quality Tire Care" recommends that the tires should not be parked on concrete. You can read about it and there explanation why on there website! They recommend if your concrete pad is dry you can use cardboard, if not rubber would work fine like one of those mud flaps you see along a road. I use untreated wood on mine 2" X 10" 2' in length. Sorry, Brett and I were posting nearly at the same time and he got on before me!

LONG TERM STORAGE OF RV TIRES
Unless the RV owner is a full-time RV-er, the vehicle
probably spends some time in long-term storage. But
what the RV owner probably didn’t know is that rubber
tires age when not being used. So, if the owner must store
the RV, a cool, dry, sealed garage is the best bet. Also, some
storage surfaces can cause tires to age faster. That’s why
Michelin recommends placing a barrier (cardboard,
plastic or plywood) between the tire and the storage
surface.

Here are some other steps the RV owner can take to
help reduce the aging effects from long-term storage:

1) Thoroughly clean tires with soap and water before
placing into storage.

2) Cover tires to block direct sunlight and ultraviolet
rays.

3) Store out of a high ozone area.

Note: When a vehicle is stored, tires should be inflated
to the inflation pressure indicated on the sidewall.

Before removing the vehicle from long-term storage,
thoroughly inspect each tire – this includes sidewalls,
tread area, and pressure. If the tires have lost pressure, be
sure to inflate them to the correct pressure before driving.

You are better having them sit on the concrete unless we are talking long-term storage at which point the weight should be off them completely. I know a little something about tire compounds...

Stop trying to over think/engineer this. Park them on Concrete

Park them on the concrete....and if they are exposed to lots of sun - cover them.

I would think that you would be better with them siting directly on the concrete >>

What's wrong with the tires sitting on concrete?
