Protect your wheels from sun and weather with RV tire covers made to fit 30 inch tires. Common matches include 215/75R17.5 at 30.19 inches and ST235/80R16 at 30.8 inches, so just confirm your overall diameter. For tandem axles with longer-than-usual spacing, choose single-wheel covers instead of a dual-axle panel for a better fit.
Match by overall diameter. Sizes like 215/75-17.5 measure 30.2 inches or 30.19 inches, 215/85-16 is 30.4, and 235/80R16 is 30.80 inches. If your tire is around 30 inches, choose 30 Inch Tires covers or ranges that include 30-32 inches. Measure diameter if unsure and compare to the cover's stated fit.
Use the securing points. Some have grommets and holes to tie a cord or bungee in back. Adding a cord around the cover helps in windy areas. If a cover fits loosely or gets looser in the sun, snug it with the rear tie-downs. After storms, double-check tension so it doesn't work free.
Installation is generally easy and quick. Slip the cover over the tread and pull it down for full coverage, then secure at the back with the grommets or strap if included. Some instructions can read clumsy, so a dry-fit first and then tightening the rear tie helps get a good fit.
They help protect tires from UV and weather, and can also shield brakes during long parking. Heavy fabric options feel sturdy; some have lasted 10 years until UV finally got to them, while others may only hold up a year or 2. Cleaning and reconditioning with vinyl cleaner can help over time.
Yes, but check your axle spacing. Standard spacing can use tandem-style covers; longer wheelbases like a 42 inch center-to-center may need single covers for each tire. If a tandem cover can't span the gap, choose individual 30 Inch Tires covers instead.
