- The ideal storage for trailer tires is in a cool, dark garage at maximum inflation.
- Use tire covers to protect the tires from direct sunlight.
- Use thin plywood sections between the tire and the pavement.
- For long term storage, put the trailer on blocks to take the weight off the tires. Then lower the air pressure and cover the tires to protect them from direct sunlight.



So what's the definition of "long term" ??
