Preserving Your RV Tires: How to Prevent Dry Rot


One of the common challenges RV owners face is dry rot in their tires. Dry rot can lead to tire failure, which is a significant safety concern while on the road. In this guide, we’ll explore effective methods to prevent dry rot and ensure the longevity and reliability of your RV tires, making your travels safer and more enjoyable.

How to Keep Trailer Tires from Dry Rotting

1. Proper Inflation

Maintaining the correct tire pressure is crucial. Underinflated or overinflated tires are more susceptible to dry rot. Regularly check and maintain the recommended tire pressure as indicated in your RV’s manual.

2. UV Protection

Exposure to ultraviolet (UV) rays can accelerate tire aging. When storing your RV, use UV-protective covers for your tires. This will shield them from the sun’s harmful rays and extend their lifespan.

3. Keep Tires Clean

Regularly clean your tires using mild soap and water. Avoid harsh chemicals that can damage the rubber. Clean off any dirt, grime, or debris that may promote dry rot.

4. Avoid Prolonged Sun Exposure

When parked for extended periods, try to park in the shade or cover your tires to minimize sun exposure. Direct sunlight can cause the rubber to deteriorate faster.

5. Tire Covers

Invest in quality tire covers designed for RV use. These covers protect your tires from the elements and provide an extra layer of defense against dry rot.

6. Regular Inspections

Frequent inspections are crucial. Look for signs of dry rot, which include cracks, fissures, or flaking rubber. Catching it early can prevent further damage.

7. Rotate Tires

Regular tire rotation helps distribute the load evenly, reducing the risk of uneven wear and dry rot in specific areas.

8. Avoid Chemicals and Solvents

Steer clear of tire products containing petroleum-based solvents. These can break down the rubber. Stick to products specifically designed for tire care.

9. Ventilation

Proper ventilation inside your RV can help reduce moisture levels. Moisture can contribute to dry rot, so ensuring good airflow can make a difference.

10. Drive Your RV

Using your RV regularly prevents the tires from sitting in one spot for too long. Tires that stay stationary are more susceptible to dry rot. Regular use also helps the tires flex, which can prevent cracks from forming.

11. Cover Your RV

When not in use, cover your entire RV. This will shield it from the elements, including the sun and rain, and help preserve your tires.

12. Inspect Valve Stems

Check the condition of the valve stems regularly. Damaged or cracked valve stems can be a source of air leakage and tire deterioration.

13. Tire Conditioner

Consider using a tire conditioner or protectant designed to prevent dry rot. These products can help maintain the tire’s elasticity.


Preventing dry rot in your RV tires is essential for safe and enjoyable travel. By following these preventative measures, you can significantly extend the life of your tires and reduce the likelihood of tire-related issues while on the road. Regular maintenance, proper storage, and proactive care will help keep your RV tires in excellent condition, ensuring your journeys are smooth, reliable, and worry-free. Safe travels!
