Keep your spare tire road-ready with the ADCO 1751 Size A spare tire cover. Built from heavy-duty UV-resistant vinyl with an elasticized back and reinforced seams, this cover shields your tire from sun, ozone, and moisture damage that cause premature cracking, dry rot, and sidewall degradation -- common problems for any spare left exposed on the back of an RV, trailer, or tow vehicle.
A spare tire that sits exposed on a rear carrier or bumper rack takes a constant beating from UV radiation, road grime, and weather cycling. EPDM and rubber compounds begin to oxidize and crack within a single season of unprotected outdoor exposure. The ADCO 1751 cover is purpose-built to stop that degradation before it starts.
ADCO is one of the most recognized names in RV protective covers, and their tire cover line is engineered specifically for the larger diameter tires common on fifth wheels, travel trailers, Class A motorhomes, and cargo haulers. The Size A designation fits a 34-inch overall diameter tire, a size frequently found on full-size rigs running LT or ST-series tires.
Thick UV-stabilized vinyl resists fading, cracking, and moisture penetration through all seasons.
Hollow bead welt cord with elastic backing pulls the cover snug around the tire for a secure, rattle-free fit.
Tear-resistant nylon thread seams hold up to highway wind buffeting and repeated removal and reinstallation.
Blocks the UV rays and atmospheric ozone that cause rubber sidewalls to crack, blister, and dry rot.
Spare tires on RVs and trailers are rarely rotated into service, which means they sit stationary in sunlight for months or years at a time. Stationary tires are actually more vulnerable to UV and ozone damage than tires in regular use, because rolling generates protective oils from within the rubber compound. A covered spare can maintain its integrity and remain serviceable years longer than an uncovered one.
The ADCO 1751 is designed to slip on and off without tools. The elasticized bead welt cord creates a uniform tension around the tire's circumference, keeping the cover from flapping or blowing off at highway speeds on rear-mounted carriers. The elastic back also accommodates minor variations in tire profile within the 34-inch size class.
ADCO backs the 1751 with a limited 3-year manufacturer warranty against defects in materials and workmanship. The vinyl formulation is UV-stabilized to resist fading and surface breakdown over multiple seasons of outdoor storage.
