Keep your mounted spare protected from the elements with the ADCO Size I Spare Tire Cover. Built from heavy-duty vinyl with a snug elasticized fit, this cover shields your tire from UV degradation, moisture, road grime, and ozone cracking -- the leading causes of sidewall failure on stored or trailing spare tires.
A spare tire left exposed to sunlight and weather doesn't just look bad -- it ages fast. UV rays break down rubber compounds, ozone causes sidewall cracking, and moisture accelerates dry rot. By the time you need that spare, it may already be compromised. The ADCO 1736 cover is designed specifically to prevent that.
ADCO has been manufacturing RV covers and tire protection products for decades. The Size I designation fits a 28-inch diameter tire, making it a common fit for travel trailers, fifth wheels, motorhomes, and utility trailers running tires in that size range. The black colorway blends cleanly with most RV exteriors.
Thick vinyl outer material resists UV rays, moisture, and road debris to extend the life of your spare tire's rubber compound.
A hollow bead welt cord with an elasticized backing wraps snugly around the tire for a secure, rattle-free fit even at highway speeds.
Tear-resistant nylon thread stitching at all seams prevents splitting under wind load and repeated on-and-off use.
ADCO backs this cover with a limited 3-year warranty against defects in materials and workmanship.
Spare tires on RVs and trailers are typically mounted externally -- on the rear bumper, under the frame, or on a swing-out carrier. In any of those positions, they receive constant UV and ozone exposure. Tire manufacturers recommend replacing tires after 5-7 years regardless of tread depth, and unprotected storage accelerates that clock significantly. A quality cover can meaningfully extend usable spare tire life.
