This fit my Tractor Supply 6'x14' trailer's spare like a glove (205/75D15). I used the chart on the description page and it worked great to determine the size to order. The cover is made of a nice slick waterproof nylon and sinches down to cover the front and back of the rubber portion of the tire (front-fully, back-only rim exposed). The major seams have double stitching, but the sinch area only has single stitch sewing, so there is a potential to fail. This is a pretty good cover for your spare tire, and I will update the review if it fails to hold up or lasts extraordinarily long.

Not much to say, it does what it is intended to do. It does look great and has a draw sting to snug it up so it won't blow off. Nice spare tire protection for your trailer / RV etc.
