How to fill a bike tire properly?

To fill a bike tire properly, first determine the recommended tire pressure listed on the tire sidewall. Use a bike pump with a pressure gauge to inflate the tire to the recommended pressure. Insert the pump nozzle onto the valve stem and pump air into the tire until it reaches the desired pressure. Check the pressure with the gauge periodically to ensure it is at the correct level. Be careful not to overinflate the tire, as this can cause damage.
