Just wanted to thank everyone for the info here. Just picked up my first 'T last week ('98 red/black). Was really excited until yesterday when I was walking up the drive after a ride and noticed something shiny on my rear tire. Turns out I got screwed in the literal sense. It was in the tire all the way up to the phillips head. New tires too. So after spending a few hours on this forum I have decided to go with the Valk sized E3. Sounds like a good tire and I am actually looking forward to a few less rpm at hwy speed. Thanks again - Tom
