If you plan on storing your motorhome outside, you’ll need good-fitting RV tire covers. Designed to prevent cracking tires and rusty rims, these tire covers will keep the sun off and the rain and dirt out. 

Finding the right RV tire covers is a straightforward process, if you know how to measure for RV tire covers

So grab your tape measure, and let’s get started.  

Step-by-Step Guide to Measuring RV Tire Diameter

Finding the right RV tire covers starts with accurately measuring the diameter of your RV tires. If you measure the diameter incorrectly, you’ll end up with a tire cover that doesn’t fit. 

If your RV’s specific tire size isn’t listed on any chart, you’ll need to measure the tire’s diameter directly to guarantee the cover will fit.

OPTION 1: Locate the Tire Size Imprint

You can find your tire size imprint on the sidewall of your RV tire. This imprint specifies the tire’s width, aspect ratio, and wheel diameter. You can look up your tire size imprint on a handy-dandy tire sizing chart like this one, and it’ll tell you what size tire covers you need.

OPTION 2: Use a Tape Measure to Measure the Diameter

Directly measuring the tire’s diameter with a tape measure is another way to determine what size covers you need. 

First, be sure the tire is properly inflated. Then, from the top center, stretch the tape measure straight down to the bottom center of the tire to measure the outer diameter.

Now, measure the width of your RV tire by spanning from sidewall to sidewall using a tape measure.

RV wheel covers come in size ranges like 19-22 inches, 24-26 inches, all the way up to 43-45 inches. Match the diameter ranges that also correspond to your tire widths, and you’ll find the option that fits your RV. 

Selecting the Right RV Wheel Covers

Having found the right sizes, there are a few different styles to choose from. Some are inexpensive and offer basic UV protection for your wheels. Others are made of higher quality materials that last longer and protect your tires in all types of weather.

Types of Wheel Covers:

There are three types of wheel covers: single-wheel covers, dual-axel covers, and axle-wheel guards. 

As the most popular type on the market, single-wheel covers are fitted to each individual tire. Dual axle covers, on the other hand, are the covers that can protect two wheels with one cover. Last but not least, axle-wheel guards span across three or more wheels.

These types of covers come in materials like nylon, plastic, or heavy-duty vinyl.

Nylon wheel covers are inexpensive. They keep the tire protected from the sun and – when fitted properly – they can keep dirt from building up in the tire rims.

Plastic wheel covers do a better job of preventing rusty rims because they keep out moisture. But plastic doesn’t last long in the sun. It gets brittle and cracks after several months. 

That’s why high-quality wheel covers are made of heavy-duty marine-grade vinyl. It weathers the sun’s UV rays better than plastic and keeps out rain and snow better than nylon.    

Fitting RV Tire Covers: Ensuring a Secure and Protective Fit

Now, because these covers come in size ranges, you still have to make sure they fit securely. After all, you don’t want your tire covers blowing off in a storm because you didn’t secure them. 

Most RV tire covers use bungee cords with hooks or elastic cords threaded through grommets to keep them securely fastened. Tire guards are secured with a bungee cord connecting two tabs on either side of the tread cutout at the bottom. 

What about Bus Chassis and Diesel Models

What if your RV has larger wheels, like those found on most bus chassis and diesel chassis models? For RV models with these chassis, Bus RV tire covers are available, fitting tire diameters from 36 inches up to 45 inches. 

RV tire covers that are specially designed for larger tire widths, as found on diesel or bus chassis, are typically indicated with labels such as XL or Bus.

No matter the size of your RV’s wheels, there’s a tire cover for you. 

RV Tire Covers for All Seasons

If you want to take care of your tires, then make sure you’re buying a quality tire cover that can last as long as your tires – if not longer. Being on the road exposes you to a wide array of weather conditions. So, opt for RV tire covers suitable for the weather conditions you plan to travel in. 

Tips for Easy Installation of RV Tire Covers

RV tire covers from reputable brands like Adco Products or Classic Accessories offer easy installation features that can simplify the process.

Snap ring tire covers, while potentially more expensive, are easy to use (aka a quick installation process) and boast a secure fit.

When shopping, look for tire covers with:

  • A bungee cord at the lower edge. This means you don’t have to crawl underneath the vehicle to secure them.
  • A top pocket or stiff wire. These make it easy to slip on your tire covers and achieve a snug fit. 
  • Options with hooks or magnets that make it quick and easy to secure

Clean the wheels and tires before installing your wheel covers to prevent dirt from getting trapped. If you choose a tire cover with grommets, follow these steps to install them properly:

  1. Loop a bungee cord through the grommets to secure the cover snugly.
  2. If a zipper is present, align it at the tire’s bottom and zip it upwards for a tight fit.
  3. When installing, fold the cover in half 
  4. Drape it over the tire.
  5. Spread the cover around the circumference, ensuring proper orientation with marked top or bottom sections.
  6. Pull on the bungee to tighten it around the wheel
  7. Secure the tightened bungee with the plastic ball clamp to keep the tension. 

If you live in a windy area, use covers with straps to keep the covers from blowing away. Make sure elasticized covers without straps are tight-fitting to prevent wind billowing and debris from building up inside your wheel covers. 

Protecting Your RV Tires

You might be questioning whether all this effort for a tire cover is worth it. Well, think about what would happen if you don’t protect your tires. 

The UV rays dry out the rubber of your tires. Fine cracks start to form…

The heavy snow buries your rims. It melts slowly, leaving your tire rims exposed to rust-inducing moisture…

When it comes time for your next RV adventure, you practically have to dig your RV tires out of the accumulated dirt and debris. 

Once you finally get underway, the tire gauge warns you of low tire pressure. Because it has been a while since you topped off your tires, you pull into the next gas to find two of your tires are severely low on air. You fill up, trying not to worry about it.

But then, at your next stop, you notice they’re already getting low again. At this point, you risk a blow-out if you don’t pinpoint and fix the leaks in your tires. So now, you must put your trip on hold, find a tire repair place close by, and fork out the cash to fix it. 

Not the best way to start a road trip.

Or…You could save yourself time, stress, and money by protecting your tires with high-quality RV tire covers. Choosing quality RV tire covers isn’t just a matter of aesthetics; it’s about protecting your investment.

Summary: Take Protection to a New Level

If something as small as slipping on some tire covers can spare you the headache of dealing with leaky tires on a road trip, then you can only imagine how it important it is to protect your rig as a whole.
