The two main types of tyre valves are Schrader valves and Presta valves. Schrader valves are typically found on cars and motorcycles, while Presta valves are commonly used on bicycles.

You can typically identify the type of valve you have by looking at the valve stem. Schrader valves are larger and have a valve core that can be removed with a valve core tool. Presta valves are narrower and have a valve nut that can be unscrewed to allow air to be added.
