How much air do you put in bike tires?

The amount of air you put in bike tires is typically measured in pounds per square inch (psi). The recommended psi for bike tires can vary depending on the type of tire and the rider's weight. It is important to check the sidewall of the tire for the recommended psi range and use a tire pressure gauge to ensure proper inflation. Over or under-inflated tires can affect the performance and safety of your bike.
