I'm on my third set of ultra gatorskins since June. I guess I ride in a war zone, also. My newest tire now has a nice slash down to the kevlar and is holding but the front has a nice screw hole through it. I got some of those Hutchinson tubeless tire patches and they are a bit@# to install. After trying to glue them in three times, I just slapped the patch on there with some duct tape and glued it from the outside. Problem solved. I recommend trying to patch your tires if you are having problems with tire damage.
