Keep your spare tire protected between uses. This heavy-duty vinyl cover blocks UV rays, rain, road grime, and dirt that degrade rubber over time -- extending the life of a tire you are counting on when it matters most.
The Camco 45343 spare tire cover is designed for RV owners who store a spare tire on the exterior of their rig. Whether you are a full-timer logging thousands of highway miles or a weekend warrior parked in the sun for months, exposed rubber degrades fast. This Arctic White vinyl cover reflects heat, sheds rain, and keeps road debris off the tire sidewall.
The wraparound attachment style secures the cover firmly around the tire without tools or straps. Heavy nylon thread stitching seals the seams against moisture intrusion -- a common failure point on cheaper covers that use standard thread. At roughly one pound, it is easy to remove and reinstall at roadside without hassle.
Vinyl shell reflects sunlight and blocks UV radiation that causes sidewall cracking and dry rot on unused spare tires.
Reinforced seam stitching resists moisture wicking so the inside of the cover stays dry even after extended rain exposure.
Elasticized or wraparound edge grips the tire rim and cover perimeter to stay put at highway speeds and in wind.
Lightweight at 1 lb, this cover installs and removes quickly -- no tools, no clips, no hardware needed at the roadside.
A spare tire mounted on the exterior of an RV is exposed to more environmental stress than tires in active use. The combination of UV radiation, ozone, heat cycling, and moisture causes rubber compounds to oxidize and crack -- even on tires with low mileage. A cracked or brittle spare is a liability when you need it most. Covering the tire is one of the lowest-effort preventive maintenance steps an RV owner can take.
Arctic White is a smart color choice for RVs. Light colors reflect radiant heat rather than absorbing it, keeping the tire surface cooler during hot-weather storage or travel in direct sunlight.
This cover is sized to fit tires with a 34-inch overall diameter. The cover itself measures 34.5 inches in diameter, providing a snug wraparound fit without excess material that could flap or come loose. The product name references the 29-3/4 inch measurement, which corresponds to the rim/section size designation used in Camco's sizing system -- always verify by measuring your tire's actual overall diameter before ordering.
Common RV tire sizes that fall near the 34-inch diameter range include certain 235/85R16, 245/75R16, and similar LT-metric sizes. Measure your spare's overall diameter to confirm fit before purchase.
Camco produces this vinyl tire cover in several diameter sizes to accommodate the wide range of spare tire sizes found on Class A, B, and C motorhomes, fifth wheels, travel trailers, and toy haulers.
