Continental labels them "Contact Speed"* Mark renamed them Basketball tires because they have that pebbly look. They're round, roll smooth and silent on pavement, and seem pretty good on hard dirt, too. A local favorite.

Wire bead.

RF = Reflex = reflective strip on the sidewalls
BW = Black Wall = NO reflective strip on the sidewalls

*original official Conti name used to be "Sport Contact II".
