I received the new 38" TrXus STS tires today. They are 15.5" wide for 15" rim. They seem as heavy as my Boggers. The are the radial tires which are currently not on the market. I am testing these tires at Disney. <a target="_blank" href=http://community.webshots.com/album/32981822vCcEVP>Spy Photos</a> Give me your feedback.
