How do storage conditions and elapsed time affect unused tires, and how should mounted and unmounted tires be stored?

Automatically reviewed answer

Hello, unused tires still age: good storage slows deterioration but does not stop it. Oxygen gradually changes the rubber, and higher temperatures accelerate this process. Clean the tires and let them dry completely, then store them indoors somewhere cool, dry and protected from sunlight, heat, oils, solvents and ozone-producing equipment such as electric motors with brushes. For tires removed from the vehicle: - Without rims: store upright and turn them every few months. Never hang them, because this can distort or damage them. - Mounted on rims: store flat, stacked securely, or suspended using suitable wheel-storage equipment. Before putting stored tires back into use, have a tire professional inspect them and check their inflation pressure. Check the manufacturing date too, and follow the tire manufacturer’s age-related replacement guidance; good storage does not give tires an unlimited life.
