Spare Tire Covers For Protection

As we driving down the road, my family always pays attention to all the travel trailers on the road.  Our family has one and it is interesting to see the different varieties of trailers on the road.  My husband always looks at the spare trailer tires mounted on the rear of the trailer and whether or not they are covered for protection from the elements.  He has his covered with a canvas type cover with a picture of a bear on it.  He looked for one with an elk but could not find it so got one with the bear as he really wanted to protect the tire from the UV rays and damage.
