Tire dry rot is not only unsightly, but it is also dangerous. Dry rotted tires are more likely to develop leaks and are more likely to fail or blow out completely. One way to prevent dry rot is to make sure the vehicle is properly taken care of. It is important to bring the vehicle in for regular maintenance inspections. This way the parts and components can be inspected based on the recommended schedule by the manufacturer. If you are not sure how often this should be, make sure to contact us.

What is Dry Rot on the Tires

Tire dry rot refers to the cracking and splitting that can occur in the sidewalls or treads of rubber tires as the rubber ages and becomes brittle. It is also known as sidewall cracking. Ozone and ultraviolet light are the primary environmental causes of tire dry rot. Tire manufacturers blend chemical ingredients into the tire during the manufacturing process in an effort to combat dry rot caused by ozone and UV exposure. Carbon black is added to the rubber to protect the tires from UV light. Waxes are added to the rubber during tire manufacturing to protect the tire against damage from ozone. If the vehicle is left to sit, the tires may develop dry rot. Make sure to check the tires regularly for any issues they might have. If you notice anything out of the norm, bring the vehicle in as soon as you can. This way you can prevent further issues and damage being done to your vehicle.

Why Classic Cars are at a Higher Risk

Vintage and classic cars are particularly at risk for tire dry rot because they are typically driven infrequently, and may be stored for months at a time. Also, camper, RV tires, and boat trailer tires may dry rot long before the tread is worn. The two primary causes of environment degradation of tires are ultraviolet and ozone and both may impact vintage cars that are parked for extended periods of time. Ultraviolet rays damage any rubber that is left exposed to direct sunlight. Ozone will degrade any rubber that is exposed to the air.

Protecting the Tires Against Dry Rot

It is important to remember to keep tires out of direct sunlight whenever possible. Also remember to keep the car in the garage, or at least covering the tires when it is stored outdoors, can help prevent ultraviolet damage. Move the vehicle periodically when it is in storage if possible. Flexing the tires during movement helps the protective waxes to work their way to the surface where they can protect against ozone. If there is any sign of dry rot or other damage to the tires, make sure to contact us as soon as you can. We can inspect the tires, and offer advice if a new set of tires will be needed. No matter if you have a classic car or one that you use regularly, you will want to inspect the tires on the vehicle.
