These are awesome, it doesn't say anywhere on the description, but its for 28" - 35" tires, for the american population. They are just wide enough to cover the tires, very light weight and sturdy. mounting position is adjustable, with the option to finalize the adjustment. Plenty of extra mounting straps and protection for sensitive pieces, and Mudflaps too. I am really impressed with the entire package, and the very small amount of assembly, was rather enjoyable.
