Review on ADCO 1755 Polar White Diameter by Justin Trujillo

I ordered this cover for a spare wheel on a camper van, size 205-75/r15. The tire is brand new so it has a full set of threads, 27" diameter, I ordered size J. The coating is very snug and runs the full circumference of the tire but only slightly covers under the threads on the back. Overall I'm happy with it, maybe the next size up would maybe cover more in the back but could also be a looser fit. I put a black plastic bag over the tire before putting the cover on to give it a little more protection.
