Hi there. I am finally getting miles on my bike after a long hiatus. Ultimately, I want to be riding the 15 miles to work in the morning. The distance is no problem, the crazy Los Angeles traffic makes me hesitant. I ride a Trek Madone with Bontrager Race tires. I have about 350 miles on it and have never had a flat... knock on wood!! About a third of my riding has been on bike paths, the rest on streets.

This thread has inspired me to be proactive about preventing flats... especially if I am riding to work because I have patients scheduled early in the morning and I don't want to be late.

Any opinions on whether the Tuffy Liners would be enough with the Bontrager Race tires or would you recommend the Continental 4 Season Grand Prix tires? It is LA, so we rarely have rain, but it might happen... more than likely I'll be facing glass and stones more than rain, but I'd like to be prepared.

Any thoughts?
