Keep your spare tire ready when you need it most. This ADCO Size J vinyl cover shields a 27-inch spare from UV degradation, ozone cracking, moisture, and road grime -- whether you're parked at a campsite for the season or rolling down the highway every weekend.
Exposed spare tires are a common source of preventable failures. UV rays break down rubber compounds over time, causing sidewall cracking and dry rot that can lead to blowouts at the worst possible moment. The ADCO 1757 tire cover is designed specifically to address that problem with durable vinyl construction and a secure, snug fit that stays put at highway speeds.
The hollow bead welt cord and elasticized back work together to grip the tire rim evenly, preventing the cover from ballooning off in wind or working loose on rough roads. This is particularly important for RVs and trailers where the spare is mounted on the rear door, under the chassis, or on a bumper rack and subject to constant vibration and weather exposure.
Thick UV-resistant vinyl resists fading, cracking, and moisture intrusion to keep your tire protected season after season.
Hollow bead welt cord with an elasticized back wraps snugly around the tire for a secure, rattle-free fit on the road or in storage.
Seams are sewn and reinforced with nylon thread to resist splitting under tension and extend the life of the cover.
Backed by ADCO's limited manufacturer warranty for added confidence in the product's long-term durability.
Tires are one of the highest-risk components on any RV or trailer. Unlike vehicle tires that stay in regular rotation, spare tires often sit stationary and exposed for months at a time. Ozone and UV radiation attack the rubber compounds in the sidewall, and once cracking begins it cannot be reversed. A cover is low-cost insurance against a roadside failure that could cost far more in towing, delays, and tire replacement.
This cover is designated Size J in ADCO's spare tire cover lineup, sized for a 27-inch overall diameter tire. Measure your spare tire's overall diameter (not the rim size) before ordering. Common tires that measure approximately 27 inches in overall diameter include sizes like ST205/75R14 and similar light trailer tire fitments, though actual diameter varies by brand and load range. Always confirm your tire's actual diameter with a tape measure.
