There are simple hand-held tire-pressure gauges which can be temporarily attached to It is extremely important for owners to have an understanding of what is safe and what is not when it comes to their tires. The three major areas to keep an eye on is the tread, sidewall, and air pressure of the tire. Having the correct air pressure in your vehicle’s tires lets your vehicle perform in the most efficient way possible. When objects such as a screw or nail puncture a tire, it creates a small leak in the tire. This leads to under-inflation of the tire. When a tire is under-inflated, it causes the inside of the tire to heat up. This heat compromises the internal structure of the tire which can lead to a blowout. When a tire is over-inflated, it wears the tread down faster, and becomes more prone to catching nails or screws in the tire. The best way to check tire maintenance is to check the air pressure, because that will lead you to whatever problem your tire might have. There are several factors that may cause quicker tire wear, among them there are heavy braking and fast cornering, constant heavy cargo transportation and rough roads, improper pressure (under- or overinflation) or improper maintenance. That’s why for the older vehicles, that do not come equipped with TPMS sensors, it is highly recommended to check tire pressure at least once a month (National Highway Traffic Safety Administration recommendation).
