What’s the difference between a Presta and Schrader tire valve stem?

Schrader tires valves are the most common valve stems found on bicycles and car tires. The most recognizable of the bunch, sometimes they are referred to as standard valves. An easy way to remember if you have a Schrader tire valve is to think of the “S.” Schrader valves are short, sturdy and standard. If you don’t know what valve stem you have, it is likely a Schrader.

The other most common tire valve stem type is Presta. Presta tire valves are traditionally found on higher-end bicycles preferred by professional cyclists. Think of the “P” in Presta standing for professional, performance and premium. If you have a Presta valve, you usually know it.
