How to Store Cars With Tire Covers to Block UV Radiation
Store your car with UV-blocking tire covers to protect rubber from degradation caused by sunlight. Use covers made of 600D polyester with silver UV-reflective backing, 0.5–0.8 mm thick, blocking over 98% of UV rays. Guarantee a snug fit with elastic hems or drawstrings, covering tires up to 35 inches in diameter. Clean tires before covering to prevent trapped moisture. Always remove covers before driving. There’s more to optimize in long-term vehicle storage.
Notable Insights

How Sunlight Damages Stored Tires
While sunlight may seem harmless, prolonged exposure can severely degrade stored tires over time. Ultraviolet (UV) radiation accelerates tire aging by breaking down rubber compounds. This leads to material degradation, reducing structural integrity. Sunlight triggers oxidation, causing the tire’s surface to crack and weaken. Cracks form as ozone attacks stressed rubber, especially along sidewalls. UV exposure depletes protective waxes that naturally migrate to the surface. Without these, rubber dries and becomes brittle. Tires stored outdoors lose elasticity within 6–12 months due to unchecked UV exposure. The glass change temperature of rubber shifts, impairing performance. You’ll notice hardening, reduced tensile strength, and increased risk of failure. Even indoor storage near windows poses risks. Material degradation is irreversible. Once microcracks form, moisture and oxygen penetrate deeper. This compounds deterioration. Proper shielding halts this process. You can prevent premature tire aging with physical UV barriers.
Do You Need Tire Covers for Long-Term Storage?
Why leave your tires vulnerable when UV damage is both preventable and costly? Yes, you need tire covers for long-term storage-especially if your car sits unused for over 30 days. Prolonged UV exposure degrades rubber, causing cracked sidewalls and reduced tread life. Tire covers block up to 99% of UV radiation, preserving elasticity and structural integrity. Without them, even proper tire rotation won’t offset sun-induced wear. Misaligned tires degrade faster under UV stress, compounding risks to wheel alignment. UV damage skews tread wear patterns, forcing premature realignment. Covers maintain consistent tire condition, supporting accurate alignment and effective rotation schedules. Most quality covers are made from 600D polyester with silver UV-reflective backing, measuring 0.5–0.8 mm thick. They fit tires up to 35 inches in diameter. Use them during storage to extend tire lifespan by 2–4 years. Protection pays-skip them, and you’ll pay later. Entry-level models like the best starter RC drift cars offer durable designs that highlight the importance of UV protection for all types of tires, whether on remote-controlled vehicles or full-sized cars.
Choose UV-Blocking Tire Covers That Fit Right
You’ve committed to protecting your tires during long-term storage, and now it’s time to get the right fit. Choose tire covers specifically designed to block UV radiation, guaranteeing they match your tire size precisely. A proper fit depends on accurate coverage design-measured by diameter and sidewall height-to fully shield tread and sidewalls. Look for elastic hems or drawstring closures that secure the cover without gaps. Material durability matters: opt for 150–200 denier polyester with UV-stabilized coating to resist cracking and fading. These materials typically block over 98% of UV rays. Poorly fitted covers flap in wind, accelerating wear. Well-designed ones maintain a snug, consistent barrier. Check manufacturer specs for your tire’s aspect ratio and width. Covers tailored to your tire’s dimensions prevent moisture buildup and guarantee consistent protection throughout storage. Fit directly impacts performance-don’t compromise. A top-performing option includes best Jeep tire covers that combine durable materials with precise sizing for optimal UV protection.
Put On Tire Covers the Right Way – Step by Step
Once the tires are clean and dry, slip the cover over the tread with the reinforced edge facing outward. Proper alignment guarantees UV-blocking material fully shields sidewalls and tread. Adjust until the manufacturer’s logo or label sits at the top, centered above the valve stem. This orientation maintains design integrity and coverage. For secure fastening, use adjustable elastic hems or hook-and-loop straps-don’t rely on gravity alone. Tension must resist wind up to 25 mph without flapping. Refer to the fitment guide below:
| Tire Width (mm) | Cover Width (in) | Fastening Type |
|---|---|---|
| 185–215 | 7–8 | Elastic w/ grip strip |
| 216–245 | 9–10 | Hook-and-loop + elastic |
| 246–315 | 11–12 | Dual strap system |
Secure fastening prevents shifting, preserving protection during long-term storage.
Prevent Flat Spots and Pressure Loss in Storage
Tire covers shield your wheels from UV damage, but proper inflation and weight management are just as important when storing a vehicle long-term. Inflate tires to the manufacturer’s recommended PSI-usually 32 to 35-to prevent flat spots. Under-inflated tires deform under the car’s weight, especially during months of inactivity. Guarantee even weight distribution by parking on a flat, level surface. Use jack stands if storing longer than six weeks to relieve tire load. You should perform tire rotation every 6,000 to 8,000 miles before storage to even out wear and preserve tread integrity. Rotate tires to distribute stored weight differently-front to back or side-to-side per your vehicle’s specs. This reduces stress on sidewalls and helps maintain shape. Solid rubber cradles or tire savers can also displace load. Proper tire prep guarantees your car rolls smoothly when you end storage.
Check and Remove Tire Covers Before Driving
Always inspect your vehicle before hitting the road, especially after long-term storage. A critical step is tire cover inspection-making certain no protective cover remains installed. Leaving tire covers on during operation creates excessive heat buildup, increasing blowout risk due to restricted airflow and elevated internal tire temperatures. Most tire covers are made from non-breathable materials like polyester or vinyl, which trap radiant heat when exposed to motion-induced friction. This can raise tire surface temperatures by up to 50°F beyond ambient levels. Driving safety precautions require complete removal of all tire covers to maintain maximum traction and prevent hydroplaning. Covers left in place may shift or detach while driving, becoming hazardous road debris. Conduct a full walk-around check: visually confirm each tire is bare and free of obstructions. Proper tire exposure ensures correct pressure regulation and tread performance. Never drive with covers attached-safety depends on it.
On a final note
Your stored tires face real UV degradation, reducing rubber integrity by up to 30% annually without protection. UV-blocking tire covers cut 98% of harmful radiation when made from polyethylene with SPF 50+ ratings. Guarantee full tread and sidewall coverage with elasticized hems for secure 25–32 inch diameter fit. Install only on clean, dry tires. Remove covers before driving to prevent overheating and tread damage.
