Camco 45325 RV Tire Cover 36-39" Arctic White 2-Pack

Park an RV or a big trailer for a few weeks and the tires take a beating you don't even see. Sunlight is the culprit. UV rays break down the rubber, dry it out, and start those fine cracks along the sidewall that turn into real dry rot down the road. The Camco 45325 is a simple fix. It's a set of two slip-on vinyl covers sized for the large 36 to 39 inch tires you'll find on motorhomes, fifth wheels, and heavier travel trailers, and it keeps the sun off your rubber while your rig sits.

Here's the thing about tire covers. They're cheap insurance. A set of tires for a big RV or trailer isn't cheap, and replacing them early because they cracked in the driveway stings a lot more than slipping a cover on. These covers shield the tire from direct sun, which is the main thing that ages rubber when a vehicle sits unused. Cover them up during the off-season or any time the rig is parked for a stretch and you slow that aging way down.

You get two covers in the box. That's enough for both tires on a single axle, or one side of a dual-axle setup. If you're covering all four corners of a tandem-axle RV or trailer, grab two sets. Each cover slips on by hand. No straps to thread, no tools, no buckles to fuss with. You just stretch the vinyl over the tire and tuck it around the tread. Takes about a minute per tire.

Fitment comes down to your tire's overall diameter, not the width. Measure straight across the face of the tire, from the ground to the top, or check the sidewall for the size and look up the diameter. If it lands anywhere from 36 to 39 inches, this cover is your size. That range covers a lot of the larger tires out there on Class A motorhomes, fifth wheels, and big bumper-pull trailers. If your tires are smaller, Camco makes covers in other size ranges, so measure first and match the range.

The cover is vinyl, so it wipes clean and shrugs off rain and road grime. It shades the wheel and hub too, not just the tire, so the whole assembly stays out of the direct sun while you're parked. Arctic white keeps the look clean and bright against the side of your rig, and it reflects sun instead of soaking up heat the way a dark cover would. When you're ready to roll again, they pull off just as easily as they went on, fold down flat, and stash in a bay until the next time you park for a while.

Where do these earn their keep? Winter storage is the big one. Rigs that sit through a northern winter or bake through a southern summer both benefit, because the tires aren't rolling and refreshing the way they do in regular use. Seasonal storage, an extended stay at a lot, a spare mounted on the back of the rig, any time the tire sits still in the weather, that's when a cover pays off. Slip them on when you settle in and pull them off when you're ready to hit the road.

A couple of honest notes. These are slip-on covers without straps, so if you're storing outdoors somewhere with steady high wind, it's worth adding a bungee or a tie to keep them snug. And they're built for parked tires, not for driving, so pull them before you tow. For what they are, though, they do the one job you need. They keep the sun off your tires and buy you extra years out of an expensive set of rubber. Simple, effective, and easy to live with.
