How to Store Your Seasonal Tires to Prevent Dry Rot and Flat Spots
How should you store seasonal tires?
Store tires in a cool, dry location away from direct sunlight and heat sources. Keep them upright in a rack or stacked horizontally in a pile, not on the rim. Maintain 50 to 85 percent humidity. Check pressure every month and reinflate if needed. Proper storage prevents dry rot, flat spots, and degradation.
Why Storage Conditions Matter
Tires degrade when exposed to heat, UV light, ozone, and moisture. Storage conditions directly impact how quickly this happens. A tire stored in a hot garage ages faster than one in a cool basement. UV light from windows accelerates rubber degradation. Proper storage slows this natural aging process significantly.
The Ideal Storage Environment
Store tires in a location that is cool (50 to 70 degrees Fahrenheit), dry, and dark. A basement or interior closet is ideal. Avoid garages with heating, attics exposed to temperature extremes, or outdoor sheds. Keep tires away from direct sunlight and fluorescent lights. Maintain humidity between 50 and 85 percent to prevent moisture accumulation.
Tire Storage Best Practices
- Store in a cool, dry, dark location
- Keep away from heat sources and direct sunlight
- Store tires upright in a rack or stacked horizontally
- Do not store on the rim to prevent flat spots
- Inflate to manufacturer's recommended PSI before storage
- Check pressure monthly and reinflate if needed
- Use tire bags or covers to protect from dust and debris
Preventing Flat Spots During Storage
A flat spot develops when a tire sits on its rim under weight for extended periods. The lower portion of the tire deforms and doesn't fully recover. Prevent flat spots by storing tires upright on a rack or stacking them horizontally in a pile. Never store tires on the rim or in contact with the ground for months. Rotate stored tires occasionally to prevent permanent deformation.
Protecting Against Dry Rot and Cracking
Dry rot appears as cracks in the rubber surface. It results from rubber losing moisture and flexibility over time. UV light accelerates dry rot. Store tires away from windows and sunlight. Use tire covers or bags to block light. Maintain proper humidity to slow moisture loss. These precautions significantly extend the storage life of seasonal tires.
Professional Tire Storage Services
Many tire shops offer seasonal storage for a fee. The shop stores your tires in ideal conditions and delivers them when needed. This is convenient if you lack storage space. Cost typically ranges from $50 to $100 per season. For those with suitable storage at home, DIY storage costs nothing.
Frequently Asked Questions
How long can tires be stored safely?
Tires can be stored for years if conditions are ideal. However, rubber degrades with age regardless of storage. Aim to use stored tires within 5 to 7 years.
Should I deflate tires before storage?
No. Store tires at the manufacturer's recommended PSI. Deflated tires can develop flat spots. Inflate before storage and check pressure monthly.
Can I store tires in a garage?
Only if the garage stays cool and doesn't have heating. A heated garage accelerates rubber degradation. An unheated garage is acceptable.
Do I need to balance tires before storage?
No. Balance tires when reinstalling them. New damage from storage is unlikely if tires are properly stored.
