For anyone who's ever fixed a bicycle flat on the side of the road while friends whiz by, the R2 Tubeless Ready Road tires are a dream. Without pinch-prone tubes, we were able to ride these rugged pieces of rubber smoothly at lower pressure, and get better traction. Sure, they are a bit harder to install (and work only on compatible rims), but we'll say it again: no flats. [$70; bontrager.com]
