How to Keep RV Tires from Dry Rotting

When it comes to owning an RV, ensuring the safety and longevity of your tires is of utmost importance.

Dry rot, also known as sidewall cracking, is a common problem that affects RV tires.

It occurs due to the breakdown of the rubber compound, leading to cracks and a weakened tire structure.

In this comprehensive guide, we will explore effective techniques and preventive measures to help you keep your RV tires from dry rotting.

By following these tips and tricks, you can extend the lifespan of your tires, improve safety on the road, and save money on replacements.

How to Keep RV Tires from Dry Rotting

Regular Cleaning and Inspection

One of the key steps in preventing dry rot is to maintain a clean and well-maintained tire surface.

Start by washing your RV tires regularly using mild soap and water.

This will help remove any debris, dirt, or chemicals that can accelerate the degradation of the rubber.

After cleaning, thoroughly dry the tires to prevent moisture buildup, which can contribute to dry rot.

Once dry, inspect the tires for any signs of cracking, bulging, or uneven wear.

Proper Inflation and Pressure Monitoring

Maintaining the correct tire pressure is crucial in preventing dry rot and ensuring optimal tire performance.

Check the manufacturer’s guidelines or the RV owner’s manual for the recommended tire pressure.

Use a reliable tire pressure gauge to regularly monitor the tire pressure and adjust as needed.

Underinflation can cause excessive heat buildup, leading to sidewall cracking, while overinflation can result in a harsh ride and uneven tire wear.

By keeping the tires properly inflated, you minimize the risk of dry rot and promote even tread wear.

Tire Covers for UV Protection

Extended exposure to sunlight and UV rays is a leading cause of dry rot in RV tires.

To shield your tires from harmful UV rays, invest in high-quality tire covers.

These covers provide a barrier against direct sunlight and prevent the rubber from deteriorating.

Ensure the tire covers are specifically designed for RV tires and fit snugly to provide optimal protection.

Using tire covers when your RV is not in use or parked for extended periods will significantly reduce the chances of dry rot.

Regular Tire Rotation

Tire rotation is a maintenance practice that involves switching the positions of the tires to promote even wear.

By rotating your RV tires regularly, you distribute the workload across all tires, reducing the risk of dry rot.

Follow the recommended rotation pattern provided by the tire manufacturer or consult a professional for guidance.

Additionally, during the rotation process, inspect the tires for any signs of damage or wear, and address any issues promptly.

Avoid Overloading and Overexertion

Overloading your RV and placing excessive weight on the tires can strain the rubber compound, making them more susceptible to dry rot.

It is essential to be mindful of the recommended weight limits specified by the RV manufacturer.

Avoid overpacking unnecessary items and distribute the weight evenly within your RV.

Overexerting your tires by driving on rough terrain or over potholes can also lead to premature tire wear and dry rot.

Practice safe driving habits and avoid road conditions that could cause excessive stress on your tires.

Frequently Asked Questions (FAQs)

How often should I inspect my RV tires for dry rot?

It is recommended to inspect your RV tires for dry rot at least once a month, or before embarking on a long trip. Regular inspections allow you to identify any signs of cracking or deterioration early on, allowing for timely maintenance or replacement.

Can I use petroleum-based products to clean my RV tires?

No, it is not recommended to use petroleum-based products or solvents on your RV tires. These substances can cause the rubber to degrade and lead to dry rot. Stick to mild soap and water for cleaning purposes.

Are there any specific tire dressings or treatments that help prevent dry rot?

Yes, there are tire dressings and treatments available in the market that provide protection against UV rays and help prevent dry rot. Look for products specifically formulated for RV tires and follow the manufacturer’s instructions for application.

Is it necessary to cover my RV tires during the winter months?

Yes, covering your RV tires during the winter months is highly recommended. Cold temperatures and exposure to ice and snow can accelerate the development of dry rot. Tire covers provide an extra layer of protection and help maintain tire integrity.

Can I repair a tire with dry rot?

It is generally not recommended to repair a tire with dry rot. The cracks and damage caused by dry rot compromise the structural integrity of the tire, making it unsafe to use. It is best to replace a tire showing signs of dry rot with a new one.

Are there any alternative materials or tire compounds that are more resistant to dry rot?

Some tire manufacturers offer specialized tires with enhanced compounds that are more resistant to dry rot. These tires are often labeled as “all-season” or “long-lasting.” Consider exploring these options when purchasing new tires for your RV.


Keeping your RV tires free from dry rot is essential for safe and enjoyable travels.

By following the tips and techniques outlined in this article, you can significantly reduce the risk of dry rot and extend the lifespan of your tires.

Remember to maintain regular cleaning and inspections, monitor tire pressure, use tire covers for UV protection, practice tire rotation, and avoid overloading your RV.

By taking proactive measures, you’ll ensure that your RV tires remain in optimal condition, providing you with a smooth and worry-free journey.
