This product is perfect and the price was very reasonable. We have a class A 36 foot motorhome and it took me two tries to get the proper size. I will admit that I'm not very well educated on tires but I did measure them. The problem was I didn't properly measure the diameter. Once I did that, then everything was fine. They appear to be as sturdy as the 10+ year old ones they replaced. I like the felt like backing. Due to the snug fit I didn't put on the straps (of course the reason for this decision was because my husband did tell me me that I didn't need to put them on. They were easy to order, easy to return the wrong size, and very easy to install. I will certainly look to this firm when it comes time to replace these covers
