Yes it has elastic ring around the edges so it stretches over the tire. Be careful pulling trailer down the road it could blow off.
As long as you order the 15" you should be fine
I'm not sure about your size tire, but it covers a spare that is on my 35' goose neck trailer.
It fits the 235/80 16 spare tire on my equipment trailer like a glove. I am thinking your CRV tire is smaller. FYI, the wrinkles come out after a few hours in the sun.
I don't know. My trailer tires are ST 205/75R14 and the cover fits good. Your tire is a larger body, with a smaller diameter, so it would be a guess as to the fit.
I bought mine for my boat trailer spares, ST205/70-R17 and they fit perfect so I'm going to say that it will not fit your larger size tire.
Best way to tell is by measuring overall diameter... Although on my purchase for a 225/75r15 for my trailer tire my purchase fit perfectly! I've done tires proffessionaly for the last 12 years and this sounds like the right fit!
measure the tire as you would a TV, diagonally . The spare tire cover I purchased fit my 15 " trailer spare, 27" should also fit 28". A warm cover is easier to fit since the fit is snug. bought the eagle cover, it looks great, good quality.
