Camco 45326 RV Tire Cover, 40-42 in, Arctic White, 2pk

Your RV's tires cost more than most folks expect, and here's the thing, they usually don't wear out from miles. They age out. Ultraviolet light and ozone break down the rubber in a sidewall long before the tread ever gets close to worn, and a rig that sits for weeks or months between trips takes the brunt of it. That's the whole job of the Camco 45326. It's a pair of slip-on covers sized for big tires, 40 to 42 inches in overall diameter, the kind you'll find on a Class A motorhome, a large fifth wheel, or a heavy travel trailer.

The material is arctic white vinyl, and the color matters more than it looks. A dark cover soaks up sunlight and holds heat against the tire. White reflects it. On a hot storage lot in July, that difference keeps the sidewalls cooler and slows the drying and cracking that turns a good tire into a safety problem down the road. Vinyl also sheds water, dirt, and road film, so the wheel behind it stays cleaner and you're not scrubbing brake dust off aluminum every spring.

Installation is about as simple as RV gear gets. You slide the cover over the tire and it stays put. No straps to thread, no buckles, no tools. When you're ready to roll, pull them off, fold them flat, and stash them in a bay. The set of two covers one axle, so a single-axle trailer is done with one box. Got a tandem or triple axle? You'll want a box per axle. It's worth counting your tires before you order so nobody ends up with an exposed one.

Fit comes down to one measurement. Overall tire diameter, straight across the face of the tire. If that number lands between 40 and 42 inches, the 45326 is your size. Plenty of 22.5 inch motorhome tires and larger trailer tires fall right in that window, but sizes vary by brand and load rating, so measure before you assume. A cover that's too small won't seat over the tread, and one that's too big flaps in the wind.

A few honest notes from folks who've run covers like these for years. They're built for parked and stored rigs, not for driving. Take them off before you tow. Vinyl and highway speed don't mix, and a cover that works loose on the road is a headache you don't need. If you store somewhere humid, give the tires a day to breathe now and then, since any cover can trap a little moisture against the rim over a long winter. And plan on covers being wear items. Season after season of full sun is hard on any vinyl.

Who's this for? Anybody who parks a big rig outside between trips. Snowbirds storing a coach for the summer, weekend campers whose trailer lives in the driveway, folks with a fifth wheel on a gravel pad out back. If your tires see sky, they see UV, and a set of covers is cheap insurance against a tire aging out early. What it's not is a security cover or a substitute for good tire care. Keep your pressures right, keep the rig off the worst of the sun where you can, and let the covers handle the rest.

Keeping them nice is easy. When a cover picks up dust or road grime, wipe it down with mild soap and water and let it air dry before you fold it away. Don't bag up a damp cover for the season, since trapped moisture is what invites mildew. Stored dry, a set will give you years of use, and because they fold flat they tuck into a storage bin without eating the space you'd rather save for camp chairs and the grill.

It's a simple piece of gear that does one thing well. Camco has been building RV accessories since 1966, and this is that kind of no-drama product. Measure your tires, count your axles, slide them on, and don't think about them again until spring.
