What is the correct pressure in the summer tires?

All about the right pressure of the tires during the summer

The tires are the only element in direct contact with the road, but the air they contain maintains the entire weight of the car. Thus, during the summer season, Maintaining adequate pressure is crucial not only to ensure the correct functioning of the vehicleBut also to ensure the safety of passengers. Are there specific requirements for this period and what tire pressure should it be maintained during the summer?

Why does the tire pressure change?

The pressure of the tires undergoes continuous changes over time. This is due to a process called exfiltration, in which air molecules run away through the tire walls. Since the typical pressure of the tires generally varies between 2.0 and 2.4 bar (for cars), a constant force pushes the air through the walls of the tire. This phenomenon occurs through microscopic spaces between rubber molecules. If we also consider permeation and losses in the valves, we can estimate a reduction in the pressure of about 0.2 bar per month.

• Pressure and temperature of the tires

The changes in tire pressure can also be influenced by the temperature. The air, like gas, contracts when it cools and expands when heated. Consequently, it is estimated that a temperature change of 10 ° C causes a pressure variation of about 0.1 bar. In addition to the temperature, there are other factors that can affect the pressure of the tires, as mechanical damage on the hips or on the strip of the bearing for tires. When you plan a trip, it is also important to take into account the temperatures at their destination, as they can differ considerably from the environmental conditions of our place of residence.

What pressure in summer tires?

During the summer season, high temperatures and sudden temperature variations can cause cyclical variations in the pressure of the tires. Even a slight deviation from the pressure level approved during approval can present significant danger and influence fuel consumption. It is therefore strongly recommended to regularly check the pressure of the tires to maintain an optimal level. If you plan a heat wave during the day, it is also possible to slightly reduce the pressure of the tires and observe the tire reaction.

• Correct the pressure of the tires

Each vehicle is equipped with tires specifically recommended by the manufacturer to ensure optimal performance. Likewise, the pressure of the tires is a crucial parameter that deserves special attention. Each manufacturer approves a specific pressure value to be maintained for each vehicle.

The information relating to the pressure of the recommended tires is generally found in various positions : On the label located in the passage of the driver’s door (to the central quantity), on the rear edge of the driver’s door, near the driver’s seat, on the fuel door or in the vehicle manual. These sources provide adequate indications for air pressure for vehicles for vehicles depending on the different loads.

When to check the tire pressure?

It is important to periodically check the pressure of the tires to take into account the effects of time, the variations of the surrounding temperature and even a possible puncture. The recommended air pressure for tires, as indicated in the vehicle’s user manual, is the «cold» pressure. This means that it must be controlled in the morning before driving, before the temperature increases or before the sun’s rays affect the conditions.

Maintaining the constant pressure of tires requires regular inspections. We recommend a minimum of once a month and before long journeys, but ideally, It should be done every two weeks. This allows you to detect pressure falls before falling to a level that probably damages the internal structure of the tire.

How to measure tire pressure?

We use a pressure gauge. If we do not have one, we can use them available in service stations or in the technical control centers of vehicles. It is important to remember that the verification of the tire pressure must be performed when the tires are cold.

• The advantages of maintaining good tire pressure

The maintenance of the appropriate pressure in the tires has many advantages. First of all, this allows you to obtain optimal performance of the tires e Reduce fuel consumption. The correct pressure of the tires also allows the driver of benefit from optimal comfort, greater duration and adequate performance to his specific vehicle. Maintaining adequate pressure, the tire temperature is controlled and rolling resistance remains at an appropriate level. In addition, the correct pressure of the tires helps to stabilize the structure of the tires, thus offering optimal reactivity, adhesion and maneuverability.

What are the effects of the incorrect pressure of the tires?

A tire whose pressure is too low can cause greater rolling resistance, which translates into a Increase in fuel consumption. Insufficient pressure can also cause a blurred sensation during the curves and give the impression that the vehicle «pulls» on the one hand. Such a tire tends to overheatwhich considerably reduces its duration. Over time, the signs of irregular usury occur on the sides of the rotating strip, which considerably reduces the properties of adhesion of the tires.

On the other hand, excessive pressure makes the structure of the tire too rigid, which limits its ability to optimally absorb the irregularities of the road. This leads to the premature wear of the suspension and the decrease in driving comfort. In addition, the incorrect pressure of the tires makes them more sensitive to various types of mechanical damage.

In conclusion, it is essential to maintain adequate tire pressure during the summer season to ensure the correct functioning of the vehicle and guarantee the safety of passengers. The pressure of the tires undergoes continuous changes due to the air through the walls of the variations of the pneumatic and temperature. It is important to take these factors into account and check the tire pressure regularly to maintain an optimal level.
