I have heard Armorall and related products are actually counterproductive and promote drying. Store the show tires out of the sun in the proverbial cool, dry place. Rubber -- it's a natural substance, and that's just the way it is. Hello all; Well that's a new one on me, to my knowledge automobile tires haven't been manufactured from natural rubber since probably the 1950's. The old pre war tires were made exclusively from it but you needed to change them about four times a year. During the war they rationed tires because tires were made from latex and latex was imported from Asia. Because of this they initially extracted latex from other plants like milkweed but eventually the chemists of the day figured out how to make synthetic rubber from petroleum, which is what they have used ever since due to it's durability. Ironically when it comes to the upholstery business latex based foam is the opposite from tires, the real thing lasts far longer then synthetic foam. As for tires probably the best way to store them is in a cool dry place without any weight on them. Ultraviolet light and heat are probably the worst enemies of any rubber, tires bearing weight in one spot on the treads causes flat spots by breaking the cords internally. So if anyone is storing their car for a long period put it on blocks with the tires off the ground I don't see what Leatherique could do for tire other then make them look pretty as Leatherique is designed for preserving porous animal hide.
