Jim:
While solid tires have their advantages, ordering them from the Airfreetires.com company is not recommended. The Better Business Bureau (BBB) gives them an F rating [1].
Just wanted my fellow readers to know they should be leery of ordering from them. I do not speak from personal experience because I heeded the warnings I read on a wonderful resource for bicycle info: www.bikeforums.net [2] The “Utility Cycling” area has a wealth of info concerning the type of info on foam-filled tires.- EliteT
