Have you seen the commercial for "Monk" where he puts an extra coaster under the coaster saying he likes to have a bacvkup? Call me Monkish but here is what I do.

#1- I make sure my tire is inflated to the max suggested on the tire. Harder the tire, the harder it is for something to poke in.

#2-I use a thorn resistant tube. They are harder to puncture.

#3-I put slime or True Goo or some such in the tires. (I use tubes with shrader valves. Wont work with Presta valves) (However, I believe specialized is selling tubes with the slime already in them)

#4-I use a liner. Mr. tuffy, chubby, or whatever.

I know, I know you are saying this is overkill. Well, I dont have flats. I am not certain which of the items above or combination there of is responsible, but it works so why should I worry about it.

I have a friend that works in a bike shop that said he never realized how many flats the Slime sealed up until some one came in to get replacement tires. The number of holes that the Slime had sealed up was amazing.
