The amount of air in the tire stays the same.The outside pressure drops about 3psi or 0,2 bar, when you are at about 2000 meters or 6000 feet. So you would expect that the pressure you measure is higher. But on 2000 meters height there is mostly a lower temperature, this lowers the pressure in the tire a bit. So it would not be strange if you measure the same pressure.
No but, tire size does effect wheel speed sensors.
A tire pressure monitoring system may produce a warning if the tire pressure is too high or too low. High pressure may cause the tire to explode or fail in hot temperature. Low tire pressure causes the tire to break down more easily.
i can effect the pressure and make gripping difficult
At high speed, there is a lot of flexing of the rubber, which causes heat, which heats the air inside the tire, which increases the air pressure. If the pressure was too high to begin with, the increased air pressure can be high enough to cause the tire to burst.
Only when the weight the tire is carrying changes after the tire's pressure has been set. For example, if a large truck suddenly dumps the load it is carrying the tire pressure will decrease. Small weigh differences (like between one human and another) should have very little effect on the tire pressure.
High Pressure
YES.
Low tire pressure or failed tire pressure sensor.Low tire pressure or failed tire pressure sensor.
Yes, definitely. Lower tire pressure increases rolling resistance and hinders fuel economy. Deflate your bike tire by a fair percentage say 50 and drive around, it isn't easy.
Because, by pressure differential, there is a gas flow from the high pressure tire to the lower pressure environment.
Tire pressure is related to what type of tire it is. the recommended pressure for the tire is on the side wall of the tire ========================================================== That is the MAXIMUM cold tire inflation pressure that is shown on the side of the tire
a difference in pressure (differential pressure). For example putting air in a tire (I know its pneumatics and not hydraulics but it is the same concepts.) the air tank is holding 110 lbs of pressure and when you connect the hose to a tire with 25 lbs the air is going to flow from the tank to the tire. or from high pressure to low pressure.
