Waste of money. I bought the right size for four RV tires. They are very inconvenient to attach. You have to crawl behind the wheels to attach them. Even then they never stay. Winds in excess of 30 miles per hour constantly blow them away. I have another set on a horse trailer. They are 12 years old and still are. They break from the sun and look terrible. But at least they stay! These cheap things cost nothing!
