The product description says it is 86 inches in diameter - that would be over 7 feet; obviously wrong. I was hoping they would fit my compact SUV tires, but their diameter didn't even come close. My tires are 235/60/18 and just under 29 inches in diameter. My guess is that your tires need to be 26" to fit exactly, maybe 27" max. The fabric and zipper looks as durable and weatherproof as I wanted it to be so disappointed I had to send it back.
