Protect your large-diameter RV tires from UV damage, ozone cracking, and weather exposure while parked or in storage. The ADCO Ultra Tyre Gard in the 43-45 inch size is purpose-built for oversized Class A motorhome and large fifth-wheel tires, and comes as a complete pair so both duals or both steer tires are covered from the start.
Large RV tires represent a significant investment, and unprotected sidewalls degrade faster than most owners expect. UV rays are the primary culprit -- they break down rubber polymers and accelerate sidewall cracking even when a rig is just sitting in the driveway. The ADCO Ultra Tyre Gard addresses this with a multilayer construction that blocks light completely and sheds moisture at the same time.
The 43-45 inch size (ADCO part 3976) is specifically designed for the largest tires found on Class A gas and diesel pushers, high-profile fifth wheels, and commercial-chassis motorhomes. If your tire measures 43 to 45 inches in overall diameter, this cover is your correct fit.
Thick vinyl outer layer repels rain, road spray, and bird droppings while blocking 100% of UV light from reaching the sidewall.
Soft flannel lining prevents the cover from scuffing painted wheel surfaces and wicks any trapped condensation away from the tire.
Elastic bungee cords with ball ends thread through brass-reinforced grommets for a snug, custom-fit closure that resists wind uplift.
Reinforced seam construction prevents thread separation and extends service life through multiple seasons of outdoor storage.
Tires that are stored uncovered -- even in shaded driveways or indoor facilities with skylights -- are exposed to ambient UV and ozone from nearby appliances and motors. ADCO's vinyl shell stops UV at the surface while the flannel backing prevents interior moisture buildup that can soften rubber compounds over extended sits. For seasonal RVers and full-timers who park for extended periods, a quality tire cover is one of the easiest ways to extend tire life.
The 43-45 inch designation refers to the overall diameter of the mounted tire and wheel assembly. To confirm fitment, measure the outer diameter of your inflated tire from tread to tread with a tape measure. Common tires in this range include:
If your tire falls below 43 inches, step down to the next ADCO Tyre Gard size to ensure a snug, wind-resistant fit. A cover that is too large will collect wind and may not stay secured.
ADCO's Ultra Tyre Gard line uses a multi-layer build designed for outdoor durability over multiple seasons:
Each cover slips over the tire face from the front. The bungee-ball cords are routed through the brass grommets at the rear of the cover and tensioned to pull the cover snug against the sidewall. No tools are required. Most installers can fit a single cover in under two minutes. For safety, ensure the rig is chocked and on level ground before working near tires.
