One major reason for maintaining proper tire pressure is to increase your safety and safety of other road users on the road. Proper tire pressure will certainly, improve your vehicle’s handling; decrease tire wear; reduce braking distance; increase water dispersion while decreases the possibility of hydroplaning; reduce rolling resistance, i.e. the force require to roll a loaded tire and enhance fuel economy. Keeping correct air pressure in your tires helps your tire to last longer and to be safer on the road. These explain why TPMS sensor is important in your car. TPMS means Tire Pressure Monitoring system and it is developed to alert the drivers or motorists when the air pressure in their vehicle’s tire is too low or dropped below the manufacturer recommended level that could create unsafe driving conditions. TPMS alerts you if your tire is under-inflated or overinflated. TPMS indicator is usually located on the dashboard. It is designed like horseshoe-shape with an exclamation point in the center. Once the TPMS illuminates on the dashboard, all you need to do at first is to check your tire pressures with a gauge to determine the tire that needed air pressure. How to read a TPMS warning light with meaning
  1. When the light turns on and stays on while driving: it means one or more of the tires are under-inflated you need to check all the tires in order to determine the under-inflated tire and add the correct air pressure.
  2. When the light turns on and off: this probably happen when the temperature or the heat builds up from driving a vehicle fluctuates.
  3. When the light blinks or flashes for about 60 to 90 seconds when you start your car and later stays on: it means the Tire Pressure monitoring System is faulty all you need to do is to visit a service centre with your car to correct the fault.
TPMS Limitations
  1. The system may be set to give warning below the tire pressure needed to carry the load in the vehicle.
  2. A time the sensor may not be able to give an accurate tire pressure data to the on-board computer.
  3. The system may not be able to correctly determine if one tire is too low than the other.
  4. The system may also not be able to correctly determine whether the tires are losing air pressure at the same rate.
Conclusion In view of these limitations it means TPMS is not a replacement for regular tire pressure checks. Therefore, it should be part of your responsibility as a car owner to check once in a month and before a long trip and when carrying heavy load.
