The Schwalbe Marathon has a 5mm thick layer built into an already strong casing. For those who can't or won't use our fine Air Free airless tires, the Marathon is one of three choices we offer. Every tire comes with a tube.  Pair this tire with a Schwalbe inner tube and you get as close to an Air Free tire without being one.

"I was impressed by the feel of the rubber. It reminded me of the really sturdy tires we had when we were kids. It has a nice smooth tread and rubber is sticky. What you notice right away is that this is a well built tire. Its' thick, strong and you can feel it. If you need a really tough tire for your high weight situation or glass infested commutes, this tire will give you a fighting chance. When you gotta' go rubber, the Schwalbe Marathon gets the Air Free Rubber Tire 'two valve stems up'."
