NBA rules state a Basketball's air pressure should be between 7.5 and 8.5 pounds.
It says how much to inflate it on the ball. or at least it should.
All the air inside of it will inflate.
When you inflate a balloon, you are adding air to it which increases the pressure inside. The pressure from the air molecules pushes against the elastic walls of the balloon, causing it to expand and inflate.
No, a basketball pump is not typically compatible with a bike tire valve.
That all depends how much helium you put in it. A basketball should be able to take the same amount of pressure, whether it's pressure from air or helium. So, if you inflate it only to the recommended pressure, it should be a problem. The same amount of pressure of helium will be less mass, so in the end the basketball will be lighter, as you would probably expect, by a very small amount.
You should inflate your bike tires to the recommended pressure level indicated on the sidewall of the tire.
A baseball is not inflate-able like a basketball, football, soccerball, volleyball or tennisball. Those particular balls are hollow with air. A baseball and softball are filled with cork and string.
To properly use a basketball air pump to inflate your basketball, first insert the needle of the pump into the air hole of the basketball. Then, pump air into the ball until it reaches the desired level of inflation. Be sure not to overinflate the ball, as this can damage it. Once inflated, remove the needle carefully and securely close the air hole.
To inflate a road bike tire properly, first check the recommended tire pressure listed on the sidewall of the tire. Use a bicycle pump with a pressure gauge to gradually inflate the tire to the recommended pressure. Make sure the pump is securely attached to the valve stem and inflate the tire in small bursts, checking the pressure frequently to avoid over-inflation. Once the tire is at the correct pressure, remove the pump and securely close the valve stem.
To inflate road bike tires properly, first check the recommended tire pressure listed on the sidewall of the tire. Use a bicycle pump with a pressure gauge to gradually inflate the tire to the recommended pressure. Make sure the pump is securely attached to the valve stem and inflate the tire in small increments, periodically checking the pressure with the gauge. Once the tire reaches the recommended pressure, remove the pump and securely close the valve stem.
Inflate your tires to the proper pressure and then drive the vehicle
To inflate a bicycle tire properly, first check the recommended tire pressure listed on the sidewall of the tire. Use a bicycle pump with a pressure gauge to gradually inflate the tire to the recommended pressure. Make sure the pump nozzle is securely attached to the valve stem and pump until the desired pressure is reached. Check the pressure with a gauge to ensure it is correct. Be careful not to overinflate the tire, as this can cause damage.
