Can Mercedes-Benz tire run 4s shop to deflate when the tire pressure is high?

Yes, but you can also deflate yourself.

However, it is best to deflate by a barometer with deflation function, otherwise it is difficult to grasp the amount of direct deflation, and it is very likely that the tire pressure will become low or too low after deflation, and it is necessary to supplement the air pressure to the normal tire pressure range.

Generally speaking, a tire pressure lower than 170kpa( 1.7bar) indicates that the tire pressure is too low; Tire pressure higher than 350 kPa (3.5 bar) means that the tire pressure is too high. The tire pressure of a normal vehicle should not be lower than170kpa (1.7bar) or higher than 350kpa (3.5bar). If the tire pressure is too low or too high, it must be caused by a flat tire or tire inflation pressure.
