It is a very common phenomena that whenever the weather becomes cooler, we tend to see more messages popping on our dashboards prompting to check up the tyres due to lower pressures. These days, thankfully to technology, we have automated TPMS ( Tire pressure monitoring systems) that help us keep the tyres safety in checks. Usually, it’s only for lower pressures. More warnings tend to mean the tyres are not in the perfect shape and needs a proper mechanic check. When it’s a hot weather, usually the tyres are inflated due to the heat generated by the rubber and sturdiness on the roads but to winters, it usually the opposite. According to the tire manfacturers association based in the USA, for every 10 degree drop in temperature, the tire pressure decreases one to two pounds per square inch or commonly reffered to as PSI on the cars. Also, we need to bear in mind that tyres have a lot to do with the fuel efficiency. When the tyre is underinflated. It causes more weight on the vehicle which tends to burn more fuel compared to when the tyre pressure is maintained properly. The popular tyre brands such as Bridgetone, Michelin, Dunlop and many others are state of the art tyres that help in maintaining the perfect balance for our cars. For our own personal safety, it is recommended to atleast check the tyre pressed once every month for older cars.
