Preventing tires from going hard/dry rotting

[mrg7243]

My dads 87 GN sat for ten years unmoved. Now its been about a year since it has been driven atleast once a month. The tires on it now ar hard and are slowly dryrotting. Since tires arent cheap (Goodwrench eagle gt's). when we invest in a new set hopefully soon what would be the best way to prevent them going hard and dry rotting. The car was parked on 1/2 plywood before it sat.

You cannot stop chemistry. As a tire ages, the base chemicals "wick off" and the rubber compound becomes brittle and looses the ability to flex. This will happen in a rather short period of time depending on the relative humidity in the storage area. Usually total degradation will occur within two to three years. It is best to just plan on replacement after extended storage. This also applies to the rubber valve stems.

I will add that if you don't drive it that much, put it on jack stands to keep the tires from getting out of round and the springs from settling.

To slow the process down

If u put a plastic bag around the tires and seal it, it will help keep the tire from dry rotting. Also keep them out of the sun as much as possible. Good Luck.
