Keep your spare tire protected year-round with ADCO's heavy-duty vinyl tire cover. Designed for a snug, secure fit on 31-1/4" diameter tires, this cover blocks UV rays, moisture, and road grime that cause rubber cracking, dry rot, and sidewall degradation -- common causes of spare tire failure when you need it most.
A spare tire that lives on the outside of your RV, trailer, or motorhome is constantly exposed to sunlight, ozone, and weather. UV radiation breaks down tire rubber faster than miles ever will. ADCO's Size C cover wraps your 31-1/4" spare in weatherproof vinyl so it stays road-ready even after seasons of storage or towing.
The elasticized back and hollow bead welt cord cinch the cover snugly around the tire without leaving gaps that let in moisture or wind-driven debris. Nylon-reinforced seams resist tearing at stress points -- important for covers that face highway wind blast and frequent removal at rest stops.
Thick, weatherproof vinyl blocks UV rays and resists cracking, fading, and surface abrasion through multiple seasons of outdoor exposure.
Hollow bead welt cord with an elasticized back stretches to conform to the tire rim and snaps back for a gap-free, secure hold.
Seams are stitched with nylon thread rated for high-stress flex, so the cover stays intact even through vibration and repeated installation cycles.
Backed by ADCO's limited 3-year manufacturer warranty -- one of the strongest in the RV accessories category for tire covers.
Spare tires are stationary -- they don't flex or cool down like drive tires do. That means UV ozone damage accumulates without the natural kneading action that keeps tires supple. A tire stored uncovered on a rear carrier or under a fifth wheel can develop sidewall cracking within a single season in high-UV regions. The ADCO cover is a simple, low-cost way to extend spare tire service life significantly.
The outer shell is heavy-gauge vinyl, the same weatherproof material ADCO uses across its RV cover product line. The Polar White color reflects sunlight rather than absorbing it, which helps keep the tire surface cooler during storage in direct sun. Stitching is nylon -- not cotton, which can rot when wet -- so seam integrity holds up in rainy climates.
ADCO sizes spare tire covers by lettered sizes (A through G and beyond) corresponding to tire diameter ranges. Size C is designed for tires measuring 31-1/4" in diameter. Measure the overall outside diameter of your mounted spare before ordering -- including the tire itself, not just the wheel -- to confirm fit. Do not measure rim diameter alone.
