Keep your spare tire in road-ready condition with the ADCO 1755 Size F spare tire cover. Built from heavy-duty vinyl with reinforced seams and an elasticized back, this cover locks out UV radiation, moisture, and road grime -- the three biggest causes of dry rot and sidewall cracking on stored spare tires.
A spare tire mounted on the rear of your RV, fifth wheel, or trailer is exposed to full sun every mile you travel and every day you camp. UV rays break down tire rubber from the outside in, leading to surface cracking, sidewall weakness, and eventual failure -- often discovered only when you actually need the tire. The ADCO 1755 cover is purpose-built to prevent exactly that.
ADCO part number 1755 is the Size F designation, sized specifically for tires measuring 29 inches in overall diameter. The cover ships individually and installs in seconds -- no tools required.
Thick vinyl outer material resists UV degradation, moisture, and surface abrasion from road debris and brush.
Hollow bead welt cord with elastic backing wraps snugly around the tire sidewall, preventing wind lift and slippage at highway speeds.
Nylon thread stitching on all seams resists tearing and separation under prolonged outdoor exposure and wind stress.
White exterior reflects solar heat, reducing temperature buildup on the tire surface and matching common RV and trailer exterior colors.
Spare tires on RVs and trailers spend far more time parked in direct sunlight than the tires actually carrying the load. Ozone, UV exposure, and heat cycling accelerate rubber oxidation on unprotected tires. By the time surface cracks are visible, the structural integrity of the sidewall may already be compromised. A cover is the simplest and most cost-effective protection available.
This cover is sized for a 29-inch overall diameter tire -- measure your spare tire's full outer diameter before ordering. Common 29-inch fitments include many standard RV trailer spare tires. If your tire measures larger or smaller, ADCO offers additional sizes in this same cover family.
Slip the cover over the face of the spare tire and stretch the elasticized back edge around the perimeter of the tire. The hollow bead cord seats behind the rim edge or tire sidewall to hold the cover in place. No drilling, no permanent mounting hardware. Remove and replace in under a minute.
