Answer:
tyre pressure monitoring system (TPMS)
Explanation:
It very important to inflate your tyres to the specified pressure. So cultivate a habit to check and refill them once a month. Note that you can't tell if a tyre is underinflated just by looking at it. If it actually looks underinflated in a way. And you can't really rely on a tyre pressure monitoring system (TPMS) only to keep track. Most systems only warn you when the pressure is 25 percent below the manufacturer's recommended tyre pressure.
