If you want to know if a particular spare tire cover will fit your RV tires, there is an easy way to find out. Simply read the numbers off the sidewall of your current RV tire. The most common tire sizes will have three parts, just like the 205/75-R15 tire pictured at right. This number will tell you the section width, the sidewall aspect ratio and the diameter of the wheel.

Once you have these numbers we will be able to assist you in choosing the right tire covers for your RV.

Hi, we have Michelin 315/80R22.5. What size covers do I need? Thanks.

@BettyM For your 315/80R22.5 tires, they have an overall diameter of just over 42 inches. This diameter falls in a size changeover for the tire covers we offer. Especially with the width of your tires, I feel that the covers that fit 40-42 inches will most likely be too snug on your tires, so I would go with a set of covers designed to fit 43-45 inch diameter tires. I have linked all of the tire covers in this size for you to check out.

For those tires the Adco White # 290-3954 or Black # 290-3974 will work really well. For a spare tire cover I recommend the Classic Accessories # 052963751208.

Your 245/70R19.5 size tires have an overall diameter of right at 33". With this in mind the Adco (Black) # 290-3971 or (White) # 290-3951 will work perfectly.
