Keep your spare looking sharp and protected year-round. The ADCO 01-1844 is a heavy-duty vinyl tire cover sized for 34-inch spare tires, built with UV-blocking materials, a soft flannel inner liner, and a patented hollow bead elastic welt cord that makes installation easy and keeps the cover snug through wind, rain, and road vibration.
Spare tires mounted on the rear of a trailer, camper, or motorhome take a beating from the sun, rain, road spray, and ozone. UV degradation alone can crack sidewalls and shorten tire life significantly. The ADCO Size A cover gives your spare a fighting chance with thick vinyl on the outside and a soft flannel poly-cotton liner on the inside that won't scuff your rim.
The US flag design is screen-printed on a white vinyl base -- a clean, recognizable look that holds up without fading as quickly as cheaper dye-transfer graphics. ADCO is one of the most trusted names in RV covers, and this spare tire cover reflects the same construction standards as their full vehicle cover lineup.
Thick, soft vinyl outer layer resists tearing, cracking, and UV degradation in all-weather exposure.
Soft inner liner contacts tire and rim without scratching -- protects your wheel finish as well as the rubber.
PVC hollow bead bungee welt sewn into the perimeter edge provides a snug, tailored fit and easier on/off than simple drawstring designs.
Seams are stitched with reinforced nylon thread rated to hold under tension and weather stress, preventing unraveling over time.
ADCO spare tire covers are sized by the overall diameter of the tire including rim and rubber, not by tire code alone. To confirm the correct size, measure straight across the face of your mounted spare tire from edge to edge. This cover fits a 34-inch overall diameter tire.
Common tires that often land near 34 inches in overall diameter include ST205/75R15, ST225/75R15, and similar light trailer tire sizes, but always measure your specific tire -- rim style and inflation level can shift the actual diameter.
Extended UV exposure is the leading cause of spare tire dry rot, especially for RVers who store their rigs for months at a time between trips. The vinyl shell on this cover acts as a UV barrier, slowing ozone and sun-induced cracking. The flannel liner also prevents the cover itself from trapping condensation directly against the rubber, which can accelerate sidewall degradation.
