LAS is the airport code for Las Vegas, Nevada, the original home of the world famous Cross Vegas cyclocross race. This mostly grass course required the fastest tire a racer could use and the LAS delivered. The diamond-file tread at the tire center offers extremely low rolling resistance for flat-out speed. However, if you take a close look at the LAS tread pattern the tread grows larger as it moves outside to the race-proven PDX side knobs for incredible grip in corners.
