Do you get more flat tires than anyone you ride with? If you're getting sidewall cuts, it could be due to the way you ride. If you go into corners too hot and slam into rocks, you might be the reason your tires can't hold up. Try easing off the throttle at the entrance of a corner and then gain speed at the corner exit. If the holes in your tires are in the center, add more air pressure. Higher air pressure makes the tires more flat resistant.
