Yes. low tire pressure on tires create more resisitance, therefore causes the engine to work harder, thus using more gas.
they hit the walls/side of the tyre and that builds pressure
Yes, you can use a car tire pressure gauge on a bike to check the tire pressure.
Pressure is equal throughout the tire.
When a car tire is inflated, the air particles inside the tire collide with the walls of the tire and with each other, creating a force that exerts pressure on the walls of the tire. The pressure builds up as more air is pumped into the tire until it reaches a point where it is equal to the atmospheric pressure pushing back on the tire.
Not typically, but running a tire with low pressure can cause damage to the tire, making it dangerous to drive and causing the tire to become out of balance. A front end vibration (sometimes called a shimmy) is typically caused by an out of balance tire.
You should not reduce tire pressure just because you are going to be on a long roadway. You should set the pressure to the cold pressure as specified by the vehicle and tire manufacturers and you should leave it alone. It is normal for the pressure to increase when the tire is hot. DO NOT bleed it off. This will cause the tire to overheat and potentially cause it to fail, possibly with catastrophic consequences. Alwaysadjust pressure when the tire is cold.
Air pressure is the same throughout the tire.
No. A car will get better mileage with the correct tire pressure.
Stabbing a car tire with a knife can cause a rapid release of air, resulting in a loud noise and a deflation of the tire. However, it is unlikely to cause an explosion in the traditional sense, as car tires are designed to withstand significant pressure. The sudden loss of air pressure can cause the tire to rupture or tear, but it won't explode like a bomb. It's important to handle tires carefully to avoid accidents or injuries.
Tire pressure depends on the tire. The pressure recommendation that come with the car are for the specific type, size and rating that came on the car.
If inside and outside same pressure that means there is no pressure. The added pressure is what blows the tire up like a balloon and holds the weight of the car up.
The maximum tire pressure is printed on the tire. Try looking in the car's manual for the correct pressure.
