No problem, I was just curious. The raised tread looks familiar and if these are the same ones then I used a pair of these in '92 to cycle around Europe on my Orange Clockwork. I woke up one morning south of Naples about 4 months into the trip to see the inner tube bulging through the walls of the rear. The front lasted all the way though - 8 months of cycling an average of 100km per day. Good tyres, but the load on the rear was too much for it. Only had two punctures in all that time, so pretty resistant to crap on the roads too.
