Keep your spare from cracking, fading, and degrading before you ever need it. ADCO's 1733 Size C tire cover wraps a 31-3/4" spare in heavy-duty vinyl, blocking UV rays and road grime so the rubber stays pliable and ready when a blowout happens miles from the nearest shop.
Spare tires mounted on the back of a motorhome, fifth wheel, or travel trailer are exposed to sun, rain, road spray, and ozone every single mile. UV degradation causes tire sidewalls to crack and dry-rot -- a tire that looks fine on the outside can fail catastrophically under highway load. The ADCO 1733 cover puts a barrier between that spare and the elements from day one.
The cover is constructed from heavy-duty vinyl with nylon-thread seams that resist tearing at the stress points. A hollow bead welt cord runs the perimeter, and an elasticized back panel keeps the cover snug against the tire face and sidewall even at highway speeds and in high-wind campsite conditions.
Thick vinyl resists UV fading, cracking, and moisture intrusion through seasons of outdoor exposure.
Stretchy elastic hem with hollow bead welt cord cinches the cover firmly around the tire for a rattle-free, secure fit.
All seams are sewn with tear-resistant nylon thread, preventing blowouts at the edges where covers typically fail first.
ADCO backs the 1733 with a 3-year manufacturer warranty against defects in materials and workmanship.
Ozone and UV are the two biggest killers of rubber that sits stationary for extended periods. A tire that runs regularly flexes and circulates antiozonants through the compound. A spare that never moves does not -- and without a cover, sidewall cracking can begin in as little as one season of sun exposure. Covering your spare is cheap insurance against a tire that looks acceptable but fails when you finally mount it.
To confirm Size C is the right cover for your spare, measure the overall outside diameter of the mounted tire (not the rim). Stand the tire upright on a flat surface and measure straight across the center from tread edge to tread edge. If your tire measures 31-3/4" in overall diameter, this cover is the correct fit.
