Schwalbe Big Apple, Very comfy tire (got these on my mountainbike since my dealer stopped selling the IRC Lovers Soul)
Continental SportContact, Very fast, very grippy, very skinny for most mountainbikes, recommended for areas with smooth riding surfaces, if you can look past the aesthetics of skinny tires on a mountainbike
IRC Lovers Soul, bit less comfy but a bit more grippy then the Big Apples, my preferred tire for urban rides (when I dont intend to do crazy things)
Maxxis Hookworms, a bit on the heavy side, but very durable and very grippy, recommended for area's with loads of potholes and stuff.
