Camco 45247 Vinyl Tire Cover 27-29 in, Black, Set of 2

Tires don't usually die from miles. They die from sitting. Sun, heat, and ozone break down the rubber while your rig is parked, and that's exactly what the Camco 45247 is built to slow down. It's a set of two slip-on vinyl covers sized for tires in the 27 to 29 inch range, which covers most travel trailers and a lot of mid-size RVs.

Here's the thing about tire aging. A tire that's driven regularly stays flexible and sheds heat. A tire that sits in one spot for weeks or months, in direct sun, starts to check and crack along the sidewall long before the tread ever wears out. UV is the main culprit, and the black vinyl on these covers puts a physical barrier between the sun and your sidewalls. Rain, road grime, and airborne dust get blocked too. When you pull the covers off in spring, the rubber underneath looks a lot closer to how you left it.

Install couldn't be simpler. You slip each cover over the tire and you're done. No straps to thread, no buckles to line up, no tools. That matters more than it sounds, because the covers you actually use are the ones that go on in ten seconds. If it's a chore, it sits in the storage bay. These don't give you an excuse.

One point that trips people up is the name. A single tire cover means each cover fits one tire, as opposed to a longer cover that spans two tires on a tandem axle. You get two of these single covers in the set. So it's two tires covered per package, not two axles. If that's not quite enough for your rig, the math is easy. Count your exposed tires and divide by two.

That makes the set of two a natural fit for a single-axle trailer, one cover per side. If you're running a tandem or dual-axle setup with four tires on the ground, grab two sets so every tire is protected. Same goes for a spare mounted out in the open. Worth covering that one too, since a spare bakes in the sun just like the rest.

A few honest notes on fit and use. Measure your tire's overall diameter before you order, not just the section width. The 27 to 29 inch window is generous, but a tire at the very top of that range wants the cover eased on rather than yanked, so the vinyl seats evenly instead of stretching thin at the seam. And these are meant for parked and stored tires. Take them off before you tow. Slip-on covers aren't made to ride down the highway.

Storage is where these earn their keep. Seasonal layup, a travel trailer that lives in the driveway between trips, an RV parked at a site for the summer, a utility trailer that only comes out a few weekends a year. Any tire that spends more time still than rolling is a candidate. Cover it and you stretch the useful life of a set of tires that aren't cheap to replace.

The vinyl itself is a practical choice for this kind of cover. It's flexible enough to slip over the tread and around the sidewall without a fight, and it wipes clean if it picks up dust or a little road film. Black hides dirt well, so the covers still look tidy after a season outdoors. If they get muddy, a rinse with a hose and a wipe-down is all they need before they go back in the bay.

Camco has been making practical gear for RVers and trailer owners since 1966, and this cover is a good example of what they do. Nothing flashy. Just a straightforward product that solves a real problem at a fair price. If you've owned an RV for a while, you already know how quickly tires can go from fine to cracked when they sit unprotected. Getting ahead of that is cheap insurance. When you're ready to roll again, the covers pull off as fast as they went on, fold flat, and tuck into a bay until next time.
