I deal with eight (8) collectable cars an a 40' diesel motorcoach storeage every winter .

You want a non-porous surface , like plastic . Not wood, not aluminum. Concrete , when covered will draw lime to the surface. Asphalt also is porous and moisture accumilates under the tires.

I also recommend that a plastic sheet ot trap be spread under the car as a barrier to ground moisture that seeps up. When the storage garages floors were poured , a vapor barrier was laid down . If you see discoloration from moisture during the winter , place the tires on a non porous surface.

it is an attempt to reduce the possibility of flat spotting...

If one is concerned a peice of pink strrofoam inuslation 2 " thick does a much better job. It deforms to the shape of the tire spreading the load over a much wider area

not necessarily true... it depends on the softness of the rubber compound.

Good year GS-D3's will definitely soft spot... been there..

Thanks for all the replies !!

I don't have any discoloration on the concrete. It was poured about 5 years ago so I don't think I am getting any migration from moisture.

Sounds like it wouldn't be a bad idea to park it on a pieces of carpet with a plastic sheet under tires. Might be a little over kill, but just in case.

Thanks again for the replies !!

The Corvette side of the garage always has a piece of indoor/outdoor carpet on the floor. Pretty cheap at your local home improvement store!

I do the same. It's kinda interesting how deep the tire imprint is after 5 months. I also inflate to 40#+. Why? Well, why not?

GOODYEAR EAGLES GS D3's here. Car is in hibernation for another two months a least. I park the car on 2 foot square 1" insulation foam as well. Maybe it is not needed, but I feel good about it!! Car cover and battery tender.

Carpet and this under ole black

At the dealership we put carpet under the showroom cars to protect the floors ONLY.We havent had a complaint of flat spotted tires in over 20 years.Sometimes a Viper may sit there for a year before being sold without any tire issues.

Not here it isn't...

i wonder how many of you use "carpet" but have steel sidewall runflats

you should see the Ferrari forum. ever pay 2500$ to get your car buffed?

Here is my moisture barrier.

I use large pieces of polystyrene foam(the pink stuff, also comes in blue). Thats just my personal preference.

I use 2x10's beveled, drive up on them, and let her sit all winter. I do all the tire inflation stuff to. During the winter I treat the tires and polish the wheel, this helps prevent the concrete floor from being stained by the silicon in the tire treatment. Just another **** way!

Do you actually think that a piece of carpet would somehow cushion the pressure of a car weighing a couple thousand pounds enough to stop a flat spot. Im thinking no lol. As stated earlier todays tires don't have the problems of old associated with flat spotting. Id be in line with the barrier idea or just pure pampering .

Crazy as it sounds, I too have heard that putting thick carpet or rubber door mats under the cars tires during the cold and freezing months will help keep them from losing air pressure while sitting on freezing concrete floors ?

As others in this thread have said flatspotting of tires is a thing of the past that occured when the tires were polyester belted. Some of the new tires will develop a flat spot after sitting for months but as soon as you drive the car a little and the tire warms up to a normal operating speed the flat spot will go away not the case with the polyester belted tires, they could take hundreds of miles for it to totally disappear.

Got a plastic floor, so no problems here.
