Why is it important to have proper tire pressure in your car?

As more and more people entrust the maintenance of their cars to professionals, checking the correct inflation of tires can help you avoid hassles.
It is essential to have the correct tire pressure in your vehicle for several important reasons:
- Safety: Properly inflated tires enhance road safety. Inadequate tire pressure can affect handling, vehicle stability, and braking performance. Under-inflated tires can cause poor grip, longer stopping distances, and increase the risk of hydroplaning. Over-inflated tires can lead to decreased traction and uneven tire wear.
- Fuel efficiency: Properly inflated tires contribute to better energy efficiency of your vehicle. Under-inflated tires increase rolling resistance, meaning the engine must work harder to move the vehicle. This results in higher fuel consumption. Maintaining the correct pressure allows you to save fuel and reduce operating costs.
- Tire lifespan: Incorrect tire pressure can lead to premature and uneven tread wear. Under-inflated tires tend to wear out faster on the outer edges, while over-inflated tires wear out more quickly in the center of the tread. Maintaining proper pressure maximizes your tires’ lifespan, saving you money in the long run by avoiding premature replacements.
- Driving comfort: Properly inflated tires improve driving comfort. Inadequate pressure can make driving rougher and less comfortable, as tires cannot absorb shocks optimally. Keeping to the manufacturer’s recommended pressure provides a smoother and more comfortable ride.

It is important to regularly check your tire pressure, at least once a month, using a tire pressure gauge. Make sure to follow the manufacturer’s recommendations regarding the appropriate pressure, which may vary depending on the car model and driving conditions.
