Keep your spare tire protected from the elements with this heavy-duty vinyl cover from ADCO. Designed to fit 25-1/2" diameter tires, this Size L cover is a reliable shield against UV degradation, ozone cracking, rain, and road grime -- extending the life of your spare so it is ready when you need it.
An unprotected spare tire mounted on the back of your RV, camper, or trailer takes a beating year-round. UV rays break down rubber compounds, ozone causes sidewall cracking, and moisture accelerates dry rot. The ADCO 1738 cover is purpose-built to stop that damage before it starts.
ADCO has been manufacturing RV protective covers for decades and is one of the most recognized names in the category. This vinyl spare tire cover uses the same construction principles found throughout their cover lineup -- tight fitment, reinforced seams, and weatherproof materials rated for long-term outdoor exposure.
Thick, weatherproof vinyl resists UV rays, rain, and road grime to keep tire rubber from cracking or drying out during storage and travel.
A hollow bead welt cord with an elasticized back wraps snugly around the tire, preventing wind from working the cover loose at highway speeds.
Tear-resistant nylon thread stitching at every seam adds durability and prevents the cover from splitting under stress or UV fatigue.
This Size L cover is sized specifically for 25-1/2" diameter tires. Measure your tire diameter before ordering to ensure a proper, secure fit.
UV radiation and ozone are the two leading causes of premature tire sidewall cracking. Keeping your spare covered -- even when the RV is in storage -- dramatically extends tire life and reduces the risk of a blowout caused by a degraded spare.
To confirm this cover fits, measure the overall diameter of your mounted spare tire from tread edge to tread edge (not the wheel or rim). This 25-1/2" cover fits tires with an overall diameter at or very close to 25-1/2". Common tire sizes in this range include ST205/75D14 and similar compact trailer spare profiles. If your tire is larger, see ADCO's Size XL or XXL options.
This cover is designed for tires with a 25-1/2" overall diameter. Attempting to use it on significantly larger or smaller tires will result in poor fitment and reduced protection. Always verify your tire's overall diameter before ordering.
