AGREE^^^^^^^^^^^^^^All depends on your driving habits. I have 2500 miles on my originals. Im getting new ones before spring..
LOL You haven't wore the New off yet.My stockers still have about 70% left on them. lol My quad prolly has about 125 hours.
Pay the extra bucks and get the Razr2. In my experience no other tire bites as well in straight line or has better control through slides as the Razr2.I was thinking of getting the Razr Ballance for GNCC racing and Ive been look at the Kenda Kutter XC for GNCC racing Im tore between the 2.
As far as the question it would depend on your driving conditions and the tires, mud tires, sport tiers, ect
