How can you identify nitrogen gas using a proper chemical test?
WebNever "bleed" or reduce the inflation pressure in a hot tire. Remember that tires lose pressure when the air temperature gets colder (about 1 psi or 7 kPa for every 10°F drop in temperature). Tires may also lose a certain amount of pressure due to their permeability (about 2 psi or 14 kPa per month). Failure to maintain correct inflation ...
