?specification? [Material]: Aluminum alloy rod.
[Size]: Diameter 1 cm, length 14.5 cm.
[Weight]: 32g.
[Color]: Silver. [Measurement range] 5-50 PSI, 0.5 - 3.5KG, 50-350kpa.
[Unit conversion instruction]: 1KG (kg) = 14.5PSI (pressure) 1KG (kg) = 100KPA (pressure). [Safety hazards of automobile tires] 1. 1. If the tire pressure is too high, the tire will be easily deformed and its life will be shortened. 2. Tires leak slowly, the car is easy to drive, it is difficult to control the direction, and the blow rate is high. 3. 3. Tire pressure is too low, causing the tire to spread, making it easier to tie to nails and increasing fuel consumption. Four. High tire pressure can accelerate tire aging, and too high a temperature can cause the tire to burst.
