1, aerate should notice safety. Want to check atmospheric pressure with barometer at any time, lest pass because of aerating much, make tire blows up.

2, come loose first aerate after heat. Car stops after sailing, the tire such as the beard comes loose aerate again after heat, because of car travel when, tire temperature rises, influential to atmospheric pressure.

3, check spiracle mouth. If spiracle mouth and core cooperate rough whole, have bulgy sunken the appearance that take and other blemish, inconvenience aerates and measure atmospheric pressure.

4, aerate should notice cleanness. The air that fills cannot contain moisture and oily juice, in case metamorphism of the balata inside the embryo damages.

5, do not exceed a level overmuch. When aerating, should not exceed deflate goes again after the standard is overmuch, because go out for a long time,also cannot aerate too much, if exceed a standard to be able to make shade line be promoted overly too much, affect the service life of tire.

6, the examination is flat. Before aerating, the dirt rub-up that should get on spiracle mouth, do not shake core, aerate after ending, apply besmear of lathery foam water to be on spiracle mouth, the examination is flat.
