Ultimately though, it's best to get puncture resistant tires. All major manufacturers make them. Specialized Armadillos, Bontrager Hardcase, Continental Gatorskins, Schwalbe Marathon Plus. Panaracer and Vittoria make ones as well, but can't remember the model names. Mr. Tuffys are a good option, but the downside is added weight and they can cut into one's tubes over time.. Airless is the surest option, but come with their own set of issues. I rode them for 2 years and can say the rolling resistance was a reasonable price to pay for 100% confidence on every commute.
Everything about cycling in general and commuting specifically is about compromise. From one's bike, days per week, componentry, accessories, security, etc. Everyone has different criteria because everyone's commute is different. Personally, I came to using SMPs w/Mr. Tuffys in the rr tires and had 3 punctures in 20 years. Others swear by Armadillos. Tire maintenence can go a long way, too. I would pick out bits of stone, shards, wire etc. Did this procedure once per week. The main thing is to lower the odds on getting a flat or slow leak in the first place. Whatever equipment or process one uses is always tailored to one's specific needs. Cheers.
