hey blue rider... congrats first of all on your metric!!!

as to tires... it really depends on the tire... race tires don't typically last as long as other tires... I ride a tire called a Continental GatorSkin... most people get 3-5000 miles out of them!! BUT I had Michelin race tires prior and everyone was impressed that I got 900 miles out of them... the Gators roll slower but I'm no racer and got tired of fixing flats... a good trade off to me...
