Anyone who has owned an RV for more than a season has learned the same lesson about outdoor exposure: time is the enemy of every material that sits in the sun. The roof membrane, the awning fabric, the window seals, and yes, the spare tire all age on the same UV clock. The cheaper the material, the faster the clock runs.<\/p>\n
The spare on the back of an RV is unusual in that it has it worse than the rest of the vehicle. The roof has a coating. The awning rolls up between trips. The tires that touch the road get rotated and replaced. The spare just hangs there, year after year, accumulating sun damage that no one notices until the day it actually has to be used.<\/p>\n
The other thing that complicates RV cover shopping is sizing. Class A motorhomes, Class C campers, fifth wheels, travel trailers, pop-ups, teardrops \u2014 each uses different tires, mounted in different places, in different overall diameters. Cover sizing has to follow the tire, not the class of vehicle.<\/p>\n
Here is the practical buying guide across the RV spectrum, from utility trailers to full-size Class A motorhomes.<\/p>\n
RV spare tire covers range from 14\u2033 (utility trailer) to 36\u2033 (Class A motorhome). Most travel trailers use 27\u2033\u201330\u2033; Class C motorhomes use 30\u2033\u201333\u2033. For year-round outdoor RV storage, Marine Grade Vinyl ($169) is the right material \u2014 lighter-grade covers fade noticeably inside up to 2 years of constant exposure.<\/strong><\/p>\n If you are between sizes or running non-standard tires, the how-to-measure guide linked at the bottom walks through the measurement. Sizing is to overall tire diameter, not rim diameter.<\/p>\n RVs sit outside more than almost any vehicle category. The spare cover gets continuous UV during long storage stretches plus highway exposure during travel. Marine Grade Vinyl ($169)<\/strong> is the right default \u2014 up to 5 year outdoor lifespan, the same fabric category used on RV awnings and outdoor furniture.<\/p>\n PU Leather ($129) works for shaded covered storage but degrades faster under direct year-round sun. Polyester ($69) is a budget option for occasional-use covers in garage-kept RVs \u2014 not the right call if the RV lives outdoors.<\/p>\n RV spares end up in several different places depending on class and build:<\/p>\n The cover wraps the wheel itself, so the mount type does not change the cover fit. Sizing follows the tire diameter.<\/p>\n All five materials use fade-resistant UV printing, but lifespan varies. Marine Grade Vinyl is rated for up to 5 years of outdoor life, PU Leather and PVC for up to 3 years, and Polyester for up to 2 years. Marine Grade Vinyl is the right pick for outdoor-stored RVs.<\/p>\n Yes \u2014 included free on every cover. Choose the “with camera hole” option at checkout. The hole is centered and sized to fit any factory or aftermarket camera position, including modern Class C rear-camera systems.<\/p>\n Yes \u2014 free design proof, no extra cost, no minimum order. Send the wording or logo at checkout, or use the custom spare tire cover page.<\/p>\n A 29\u2033 cover fits ST205\/75R15 tires, which run about 29 inches in overall diameter. For non-standard sizes, measure across the spare and use the universal size chart.<\/p>\n Especially in that case. A stationary RV gets constant UV on the same surfaces day after day, with no rotation or movement to spread the wear. Marine Grade Vinyl extends the spare’s usable life by years compared to leaving it uncovered.<\/p>\n Browse RV covers \u2192<\/strong><\/a> \u00b7 Travel trailer \u2192<\/strong><\/a><\/p>\nSizing by RV class<\/h2>\n
