I've probably had the worst luck out of anyone in this entire forum when it comes to flat tires. I've got a decent road bike that weighs fairly light, me weighing in at about 2 bills. I've probably went through at least $80 in tires and C02 over the past couple weeks. It's like I get a flat every other day. I've tried slime, thin tubes, thorn resistant tubes and kevlar tires. All have a tendency to go flat if not sooner than later. Almost always pinch flats, but I've even had the people in bike shops put them in there for me perfectly. I'm careful how I ride, but there's so much damn debry on my route that it doesn't take more than a couple days till they go flat again and I'm trhowing down yet another 20-30 bucks on tubes.
What does it take to get a good, light-weight, reliable flatless tire? One that you could drill holes through and still ride on without even sacrificing a significant amount of performance compared to tubes.
If you know of any good flatless tire brands out there, I'd like to know since I'm simply fed up with tubes. I don't even care if I go 5mph less than I would with tubes. In my case going slower and a bumpier ride is way better than getting stranded.
I use my bike to commute to and from work (16 miles round trip everyday). It already sucks up over an hour out of my day just riding my bike, I simply don't have the time to deal with flats. Which for me seems to be inevitable with tubes.
