How to Prevent Dry Rot

There are plenty of easy ways to prevent tires from dry rotting. Check your tires for proper inflation on a regular basis, even if you don’t plan on using that RV, trailer, or vehicle anytime soon. That being said, take them out for a drive every once and a while. Tires get brittle as they age. Regular usage helps promote elasticity, just like exercise does for muscles in the human body. When storing tires, store them in a cool, dry area with no sun exposure. Ozone and UV damage tires over time. On that topic, tires have protective chemicals in them that slow ozone/UV damage. Many tire cleaners breakdown these chemicals or are harmful to them. Try to find a cleaner that doesn’t damage your tires.

What is Dry Rot?

Dry rotting a two-fold process whereby a rubber tire is structurally compromised and is then infested with the dry rot fungus. The fungus’s scientific name is Serpula Lacrymans, the same stuff that eats away at timber. The fungus spreads across the tire, considerably weakening the tire’s integrity as the fungus grows. As tires are one piece of rubber, there is no way to “fix” one with dry rot. The tire must be disposed of.
