Protect your RV or trailer tires from UV degradation, cracking, and weather damage with the ADCO Ultra Tyre Gard in black. Built from heavy-duty flannel-backed vinyl and engineered with overlapping seams and double-needle stitching, these covers are designed for seasons of storage use. Size 3 fits tires with an overall diameter of 27 to 29 inches. Each purchase includes two covers -- enough for one axle.
RV tires are expensive and vulnerable to sun damage even when the rig is parked. UV ozone cracking can degrade sidewalls rapidly, leading to dangerous blowouts on the road. The ADCO Ultra Tyre Gard is purpose-built to block that UV exposure and repel moisture while your rig sits in storage or at a campsite.
ADCO part number 3973 (vendor part 01-1181) is the Size 3 variant in the Ultra Tyre Gard line, covering tires measuring 27 to 29 inches in overall diameter. This size is commonly found on Class A motorhomes, fifth wheels, and larger travel trailers using tires in the ST225/75R15, ST235/80R16, or similar size ranges -- always verify your actual tire diameter before ordering.
Flannel-backed vinyl shell repels rain and morning dew while the soft inner lining protects the tire sidewall finish from abrasion.
The bungee-ball system cinches snugly behind the tire, keeping covers secure in wind without tools or tie-downs.
Grommets at stress points resist tearing and maintain fastening integrity across repeated seasonal installs and removals.
Reinforced seam construction prevents moisture intrusion and adds long-term structural durability to the cover edges.
Each order includes two (2) ADCO Ultra Tyre Gard covers. One pair covers a standard tandem or single axle. For a dual-axle trailer or motorhome with four tires exposed, order two pairs.
Measure the overall diameter of the inflated tire from the ground to the top of the tread at the 12 o'clock position, or read the sidewall markings and use a tire diameter calculator. Size 3 (Part 3973) covers 27 to 29 inches. ADCO offers additional sizes in the Ultra Tyre Gard line for smaller or larger tires -- confirm your measurement before purchase to ensure a snug, wind-resistant fit.
Size 3 at 27-29 inches is a popular fit for tires such as ST225/75R15, ST235/80R16, and LT245/75R16 in various load ranges. It also suits many 16-inch passenger-car-type wheels on lighter trailers. Always verify your actual inflated tire diameter against the 27-29 inch range -- tire diameter can vary slightly by brand and load rating even within the same nominal size.
