How Much Tyre Pressure Is Best for Better Car Mileage? Check the Complete Details

UdaipurTimes, September 07, 2026 | Automobile News: Checking your tyre air pressure is crucial for proper driving. Ensuring the proper amount of air in the tyres is essential for driving safely. A low air pressure in tyres leads to overheating in the tyres. In addition to overheating, low air pressure creates problems with braking and steering and leads to quick tyrewear. However, too much air reduces the grip of the tyres on the road. Therefore, keeping the proper tyre pressure enhances fuel efficiency, improves comfort and increases the lifetime of tyres.

When to measure tyre air pressure?

It is advisable to check the pressure of tyres when they are cold. If you drive, the temperature of the tyres increases, resulting in an increase in the air pressure as well. Therefore, if the car has not travelled for a long time, one should probably wait for a few hours before measuring air pressure. It is advisable to measure tyre pressure at least once a month and before the beginning of any trip.

How much PSI should you keep in the tyres?

The recommended tyre pressure can be different for each car. It can also depend on the car model, tyre size and the number of passengers or the amount of additional load in the car. Therefore, follow the sticker on the car, the owner’s manual or the manufacturer’s recommended PSI when checking the tyre pressure.

Tyre pressure has a special relationship with temperature

Tyre pressure also changes with changes in temperature. The pressure may decrease in cold weather and increase in hot weather. It is especially important to maintain the correct tyre pressure during the rainy season when the roads are wet. Proper tyre pressure helps maintain better grip and control on wet roads.

Nitrogen or regular air?

Although using nitrogen in tyres is popular, it is not always necessary for ordinary cars. Regularly checking the tyre pressure and filling the tyres when needed are the most important things. Even if you use nitrogen, you should still maintain the recommended PSI.

You can also understand the problem by looking at tyre wear

Excessive wear in the middle of the tyre can indicate overinflation. On the other hand, if both edges of the tyre are worn out, it may indicate low tyre pressure. Therefore, check the tyre pressure regularly and do not forget to check the spare tyre as well. Maintaining the correct tyre pressure can improve safety, control and tyre life.
