I have just plain cement floors in my grage, to keep my nylon cord tires from flat spoting. Would puting wood under the tires help?

Re: tire storage
I would either get the weight off the tires or look into these things called tire cradles. Some of the corvette catalogs might have them or Eastwood company might. I am sure someone else might know more about them. I am not sure how well the cradles work. I do recall reading about a product just recently that stated it was for prevenenting flat spots though.

Re: tire storage
Flat spotting is usually temporary and the tires will round out once they are warmed up from driving.
Fill them to the maximum cold pressure placarded on the sidewall or at least 35 psi. You DO NOT want to store a car on jackstands as this will strain the suspension bushings in torsion.
I don't know if concrete can degrade rubber or whether it's an old wives' tale, but if you're concerned, cut some squares of 3 mil or thicker plastic tarp materinal and roll the car onto them.

Re: tire storage Duke
On a solid axle car if you support the rear axle tubes on jackstands, the suspension will settle to normal ride height, so this is okay for storage.
At the front, even if you support the lower A-arm as far outboard as possible, the suspension will not settle to normal ride height because the leverage point is inboard of the tire contact patch.
On IRS models there is really no way to support the rear suspension on jackstands, so most guys place the jackstands on the frame and let the suspension droop to full rebound, which then causes the suspension bushings to be strained in torsion, and extended periods in this condition can cause the rubber to "creep" and possibly damage the bushings.
As long as tire air pressure is maintained and they don't go flat, tires are rarely damaged in short term storage, and even if tires are damaged, they are much easier/cheaper to replace than suspension bushings.

Re: tire storage Duke
I agree with Duke. I would never store a car on jack stands and I still don't understand the concept or what it's supposed to prevent, other than the flat spot problem. The body distortion is a lot worse than most think if the chassis is supported incorrectly, especially in a converible. Mount up an old set of tires on cheap incorrect wheels for the winter.- Top
