I measured my trailer tires carefully, they were 26-26.5 inches wide and while the covers fit, they are too narrow and don't reach the wheel leaving about 2 inches open. I would send them back but not worth the hassle. I'll just replace them in a few years. UPDATED: The company noticed my review and sent me the next size up. It's difficult to measure tires, and if you're on the higher end of the size range, go up one size.
