Depends on what valves your tubes are equipped with.
See link below for descriptions and how they work
Air fille bicycle tires were invented by John Dunlop.
Solid bicycle tires offer benefits such as reduced risk of punctures, no need for inflation, and longer lifespan compared to traditional air-filled tires.
The recommended air pressure for bicycle tires is usually printed on the sidewall of the tire. It is important to inflate the tires to the specified pressure to ensure optimal performance and prevent damage.
actually bicycle tire or for that matter any kind of tire does lose air, the heat in the summer causes the air in the tires to expand. That's why is not a good idea to fill your tires to the max in the summer time.
You should change bicycle tires when they are worn out, have visible damage, or are not holding air properly. It is recommended to check your tires regularly for signs of wear and replace them as needed to ensure safe and efficient riding.
A compressed air bike pump works by using a piston to pressurize air in a chamber, which is then released into the tire through a nozzle. This process allows for quick and efficient inflation of bicycle tires.
The recommended air pressure for bicycle tires is typically between 80-100 psi (pounds per square inch) to ensure optimal performance and safety.
Usually the pump or compressor just takes air from the surrounding and pushes it into the tube/tire.
I'm assuming you're referring to the tubes in the tires here. The purposes for using air-filled tubes in bicycle wheels are comfort, traction and weight. W/o air filled tires, the option is solid tires, and solid tires gives a harsher ride on uneven surfaces, poorer traction and a higher weight.
Tannus Tire Armor provides puncture protection, eliminates the need for air, offers a smooth ride, and reduces maintenance costs for bicycle tires.
To use a bicycle tire valve stem adapter to inflate your tires with a different type of air pump, simply attach the adapter to the valve stem on your tire and then connect the other end of the adapter to the nozzle of the air pump. This will allow you to use the different type of air pump to inflate your tires.
Bicycle tires lose air due to a combination of factors, including small punctures, leaks in the valve stem, and natural permeation of air through the tire material. These factors can cause gradual air loss over time, requiring periodic inflation to maintain proper tire pressure for optimal performance.
