Tire, Shinko Golden Boy Trail Wing 400 x 8. Nice aggressive tread pattern that is very close to the original design of the Bridgestone, see picture for comparison. This tire is a very nice tire that is about 9/16″ taller and 1/2″ wider than the Bridgestone Trail wing. If you are looking for a little larger tire for your bike with the same look at the original trail wing, this tire is your fix.
