Which tire do you guys feel is the best for flats? I have tried a few. Currently on my new Trek 5.2 they are race lite tires, and already 3 flats in the last 3 rides, just side of the road trash nothing razor sharp. So I need some new rubbers (tires that is). So any suggestions would do fine, and please do not say anything about slime, one just punctured today on a 30 mile ride, and i got it all over my hands ugh!
