Keep your spare tire protected from sun, rain, and road grime with the ADCO Size B vinyl tire cover. Engineered for a snug, secure fit on 32-1/4" diameter tires, this cover shields rubber from UV degradation and weather damage that leads to cracking, dry rot, and blowouts when you need that spare most.
A spare tire that cracks, dries out, or degrades in storage is no spare at all. ADCO's Size B tire cover wraps your 32-1/4" tire in heavy-duty vinyl designed to block UV rays and resist the outdoor elements that attack rubber over time -- whether your rig is parked for the season or rolling down the highway every weekend.
The hollow bead welt cord and elasticized back work together to hold the cover firmly in place against wind and vibration. Seams are stitched with tear-resistant nylon thread, so the cover holds up over years of use without splitting at the edges.
UV-resistant vinyl construction blocks sun damage and repels moisture to keep your spare tire rubber supple and road-ready.
Hollow bead welt cord with elasticized back stretches to grip the tire firmly and resist wind lift during travel or in storage.
Tear-resistant nylon thread stitching along all seams prevents splitting and extends the life of the cover under regular use.
Backed by ADCO's limited 3-year warranty, giving you confidence in the product's long-term durability and UV resistance.
Spare tires mounted externally on bumpers, swing-arms, or under-carriage carriers are exposed to constant UV radiation, road chemicals, ozone, and moisture. Rubber degrades significantly faster when unprotected -- ADCO's vinyl cover acts as a barrier between your tire's sidewall and all of those elements.
RV rubber tires are especially vulnerable to UV cracking because they often sit stationary for extended periods. A tire cover is one of the lowest-effort, highest-return maintenance items you can add to your rig.
This is the Size B cover, designed specifically for tires with a 32-1/4" overall diameter. Measure your tire's diameter before ordering. ADCO offers multiple size options -- fitting the correct size ensures the elasticized back grips properly and the cover stays put at highway speeds.
Measuring your tire diameter correctly ensures the right fit. Measure the full outside diameter of the mounted tire -- not the rim size. For a 32-1/4" fit, typical tire sizes include:
If your tire falls near the boundary between sizes, choose the Size B if the diameter is at or near 32-1/4".
This listing is for one (1) tire cover. If your RV carries two spares, two covers will be needed.
