DH recommends the Continental Grand Prix 4000s $49.99 each at WheelWorld.com. They also have the Continental Ultra Race folding $17.99

The GP 4000s is a training / race tire, that wears better and longer than a lot of others. The Ultra Race is rated as a good tire to get your base miles in.

As you may notice, DH is a continental guy. And his choices in tires have always worked for me.
