Understanding Tire Dry Rot: Causes and Prevention
Tire maintenance is a critical aspect of road safety that often goes overlooked. One of the common yet lesser-known issues affecting tires is dry rot. Dry rot can significantly compromise the structural integrity of tires and increase the risk of accidents. In this article, we'll shed some light on how it happens and how to avoid it.
Common Causes of Tire Dry Rot
Tire dry rot is a gradual process that occurs due to a combination of environmental and usage factors. Some of the most common culprits behind this issue are:- UV Radiation: Exposure to sunlight and ultraviolet (UV) radiation is a major trigger for tire dry rot. The rubber compounds in tires are vulnerable to UV rays, leading to the breakdown of the tire's molecular structure over time.
- Heat: High temperatures can expedite the chemical reactions that lead to tire degradation. When tires are parked for extended periods in direct sunlight or near sources of heat, the rubber can become less flexible and more prone to cracking.
- Underutilization: Tires that are left sitting for extended periods can develop rot. This is often the case with vehicles that are stored in garages or storage facilities for months without moving.
- Poor Maintenance: Neglecting proper tire care, such as cleaning and applying protective treatments, can exacerbate the effects of dry rot.
How To Prevent Tire Dry Rot
While tire dry rot is inevitable to some extent due to the natural aging of rubber, there are several steps you can take to minimize its occurrence:- Regular Inspection: Routinely inspect your tires for any signs of dry rot. Check the sidewalls and tread for cracks, fissures, or other irregularities. Catching the early stages of dry rot can help prevent further deterioration.
- Proper Storage: If you have a vehicle that you don't use frequently, consider placing it on jack stands to prevent the tires from bearing the vehicle's weight. This can help alleviate stress on the rubber and reduce the risk of dry rot. You should also take the car out of storage for a drive occasionally to ensure the tires are rotated. More on that below!
- Clean and Protect: Keep your tires clean by washing them with mild soap and water. Avoid using harsh chemicals that can accelerate rubber breakdown. You can also apply a tire protectant with UV inhibitors to create a barrier against UV radiation.
- Regular Use: Using your vehicle regularly can help prevent dry rot by flexing the tires and distributing the oils within the rubber compounds. If you have multiple vehicles, consider rotating their usage.
