I have been driving my van on spare tires at 60mph and done 200 miles and they have snapped etc. I have 2 on my trailer that I use from time to time and the covers are cheaper and fell apart, just sitting on the hoop doesn't move and you're ripped when you pop a hoop on. I've had leathers that have lasted me for years with no problems and no satisfaction. All of these 6 have lasted less than 6 months and will not cover the tire or have about 3 inches of tire loose on the trailer tires and not the car tires.
