Tire levers are a necessity when riding. Without them, changing a tire will not be easy. Many people choose plastic for rides because they are lighter and cheaper. Most shops will have metal levers because they work better and last longer. Metal levers are about $15.00.
Park tool makes some very functional levers for about $2.95 for a pack of three that snaps together to take up less space. The proper way to use them is to wrap one around a spoke (that stays in place) and use the second one to pry the tire away.
To actually change a tire, follow these steps:
1. Open brake;
2. Remove wheel;
3. Remove tire and tube;
4. Inspect tire;
5. Install tire and tube;
6. Inflate and seat the tire.
