Travel Trailer Spare Tire Covers — Sizes 27 to 30 Inch for RV Trailers

Your travel trailer's spare tire lives on the bumper or A-frame carrier between every trip — fully exposed to sun, rain, and road grime. A travel trailer spare tire cover in the right size protects the sidewall from UV cracking that can make a spare unsafe even if it was never driven on.

How to Find Your Travel Trailer's Spare Tire Size

1. Locate your spare tire (usually mounted on the rear bumper or A-frame carrier)
2. Measure the outer diameter of the inflated tire — from edge to edge through the center
3. Round to the nearest whole inch
4. Select that size at checkout — most travel trailers use 27, 28, 29, or 30 inch

Why UV Protection Matters for Travel Trailer Spares

Spare tires stored in direct sunlight develop ozone and UV cracking in the sidewall over time. This damage occurs whether or not the tire is ever driven on — it's caused purely by UV and ozone exposure. An unprotected spare sitting through one full summer can develop cracks that make it unsafe for emergency use. A quality UV-resistant cover prevents this degradation at a fraction of the cost of replacing the spare. See also: 5th Wheel covers and Utility Trailer covers.

Popular Travel Trailer Cover Designs

Camp life and outdoor-themed designs are consistently the most popular choices for travel trailer owners: mountain sunset landscapes, campfire and tent scenes, wildlife art, and national park-inspired compositions. American flag and patriotic designs are also popular, particularly for owners who travel across the country.
