What is the inflated pressure value of a car tire?
Common 55-65 flat ratio, width 195-225 interval, tire pressure maximum not more than 3bar, standard tire pressure is 2.3-2.5Accurate tire pressure, look at the tire side wall, English PSI, followed by figures 14.5 = 1bar
According to manual selection, about 2.5MPA or so.Tire pressure is too high and low point, will shorten the service life of the tire. Will make the matrix deformation increases the pressure is low, sidewall cracks easily occur at the same time has the deflection movement, resulting in excessive heat, caused the rubber aging, fatigue ply, cord broken, will make the tire contact area increases, accelerate the shoulder wear. The pressure is too high, will cause the tire cord done by excessive deformation, carcass elasticity decreased, so that the car has been increased in a moving load, if the impact will crack and burst, while high pressure will accelerate the tread wear and rolling resistance performance decline.
Each brand may vary in order to tire material prevail.Find the word "MAX PRESS" on the tire side. The following figure is, for example: MAX, PRESS, 340kPa (50PSI) immediately, the tire is under normal circumstances, the maximum safety inflation pressure.But how much is the tire pressure when the tire is mounted on the vehicle?Please inflate the tire pressure recommended by the car plant. You can find the tire pressure recommended value of the vehicle in the user manual or the cab door (near the B column), the fuel tank cover, the storage tank and so on, marked with the tire type.The recommended tire pressure is usually the tire pressure measured under the condition of cooling.A tyre cooling condition is defined as a minimum of three hours after parking or a tire running no more than 2 km. If you can only measure the tire pressure during the hot tire, please subtract the measured tire pressure value by about 0.3 bar (= 4psi), that is, the tire cooling and charging pressure.
