Can't answer your question w/o more info. How much do you weigh? Do you carry cargo on your bike? What tire size (width especially), make, model do you use now? How much air pressure do you run?

I weigh 185, do carry up to 20 lbs routinely, I use 700x25 and 700x28 Specialized Armadillos and cheapo generic tubes over horrible, horrible trash-laden roads in Houston and get a flat about 4x a year. About a flat per 1000 miles. That includes night riding (commuting) where I can't see tiny debris, and run over it.

For my daytime recreational riding, I haven't had a flat in several years. I've never had to use the air pump that I bought for this bike. It just sits there idle.

Oh, for sure, if you get flats, lose the CO2 cartridges and get a good pump. I mean, that's like washing your car with little bottles of Evian or Perrier.
