Mr. Tuffy Bike Acc. Tire Liner Flat Protection

While no product can prevent all glass/thorns/nails/whatever from getting to your bicycle tubes, Mr. Tuffy has made me breathe a lot easier. Go out on a daily ride and your path often covers broken glass, nails and all sorts of thick thorns. After installing Mr. Tuffy on your bike (and also the wheel of your bike trailer), you'll be way better protected.
