I noticed my tire pressure was low toward the end of the ride. This morning I found a small piece of metal in my tire.
While I was removing the piece of metal, I found lots of glass expected from urban cycling. Below are some steps I use to prevent future flats from the same sneaky glass that can still be hiding in your tires.
– Before starting to make sure you have safety glasses or old biking glasses to wear for eye protection.
– Deflate your inner tubes and remove your tires.
– Inspect the outside of your tires and look for shards of glass, metal, etc. if you see a something pinch the tires and pry the object out with a pin or something similar. Do not poke the pin through the tire and cause damage to the tire.
– Inspect the inside of the tire, do not rub your fingers inside the tire and feel around for the glass or anything you may cut yourself. (I’ve heard it’s tempting)
– If the rear tire is more worn out than the front tire, you may want to rotate them. Most of the weight on your bike is typically on the rear, so you want the tire with more tread in the rear. Pay close attention if you do rotate the tires and look for tire direction arrows so you reinstall them correctly. Most tires with a tread are directional, and the arrow should point in the direction of the natural tire rotation when the bike is moving forward.
