Keep your spare tire ready when you need it most. This ADCO Size E vinyl cover shields your spare from UV radiation, ozone, moisture, and road grime -- the four leading causes of sidewall cracking and rubber degradation on stored tires. Sized specifically for 29-3/4" diameter tires common on RVs and trailers, it installs without tools and stays put mile after mile.
A spare tire mounted on the back of your RV or underneath your trailer is constantly exposed to sunlight, weather, and road debris. Without a cover, UV rays break down the rubber compounds in the sidewall, leading to dry rot, cracking, and eventually a tire that is unsafe to use when you actually need it. The ADCO 1734 is designed to prevent exactly that.
ADCO has manufactured RV protective covers for decades, and this spare tire cover is built to the same standard as their full-rig covers: heavy-duty vinyl shell, reinforced seams, and a snug elasticized fit that does not flap or come loose at highway speeds.
Thick vinyl outer layer resists UV rays, moisture, and road grit to keep your spare protected year-round.
Hollow bead welt cord with elastic backing stretches to fit snugly around the tire and stays secure while driving.
Nylon thread stitching at all seams resists tearing and delamination even under repeated tension and UV exposure.
ADCO backs this cover with a limited 3-year warranty against manufacturing defects.
Most RV spare tires are mounted externally -- on the rear bumper, a swing-away carrier, or an A-frame tongue carrier -- where they receive full solar exposure every day. UV ozone degradation can make a tire unsafe in as little as 3-5 years even if it has never been used. A quality vinyl cover dramatically slows that process, extending the usable life of an expensive spare.
This cover is also useful for tow-vehicle spares, boat trailers, utility trailers, and fifth-wheel spares mounted in under-bed carriers with external access doors.
