I went with the Spartacus tires from Greenball. I ride in alot of loose sand aswell as hardpacked trails. Check thier website out you might find somthing you like. P.S. I purchased through Discount tire's also known as Americas tire. They were able to order them for me for alot less than Greenball's advertised price. Take your time and shop around. That's what I did, and I'm extremly happy with the tires I went with. Good Luck!! Let me know what you get. I'm always interested in the upgrades fellow Hawk owners have done!
