There were some significant differences between tire technology in 1938 and 1978. That alone would lead to a different treatment for long term storage. Your best advice would come from the tire manufacturer. Check their website or send them a note. Don't take our word for it... If you are leaving your car for a number of years, I would say flat spots are the least of your worries - you would want to replace the tires just due to ageing. If you know you will be storing the car for more than 6 months, I would remove the wheels and tires, put the car on jack stands on the suspension. Don't let the suspension sag or you will ruin the suspension bushings. Store the tires in a dark place, as light tends to accelerate the outgassing of the compounds in the rubber. -- Mike -------------- Original message from robert parker <roberthparker@xxxxxxxxxxx>: -------------- > Indeed, that brings up a curiosity: I think in my 1938 Buick Shop Manual, it says for extended non-driving times, to OVER inflate the tires (they, like the DeLorean, are low-pressure tires). However, in my 1978 Suzuki 550 Owner's Manual, it recommends DEFLATING the tires by ~1/3. Why the difference? I found that rather interesting.
