We always wonder where the tire pressure setting at 30Psi came from. We also wonder whether all tire pressure pumps have the same calibration.

PSI is the abbreviation for Pounds Per Square Inch which is the measurement for tire pressure.

The truth of the matter is:

You can even set your tire pressure at 60Psi which is double what you set and you will still move. It won't burst the tire. At this age when most of us have tubeless tires, we are lucky since the rubber things can handle extreme pressure.

However; at 60Psi, you will have the bumpiest ride of your life. High tire pressure gives the vehicle poor handling and steering becomes a nightmare.


The stability of the car is entirely dependent on the wheels. They are the only point of contact to the ground.

If you are a slow driver, you can have your tire pressure at 60Psi and you will roll just fine.

BUT, if you are a race driver on the road, kindly have your tire pressure at 25Psi. If you are rolling very fast and your tires are full of pressure, what is likely to happen when you brake suddenly is that the car will skid and you wont like the experience.

In regards to the fuel consumption, high tire pressure gets you lower mileage per liter of gasoline. This is because with poor handling, the vehicle requires higher energy levels to work any terrain.

High tire pressure even wears out the tires faster not only with skidding when you brake at high speed but also with rough contact between the tire and the road. This is when you see your tires wearing out at the middle while the edges of the treads are still new.


The best tire pressure for your car is written at the door of your car. Just check on the driver's door and you will see the recommended tire pressure.

The tire pressure written on the tire is the maximum pressure it can handle not the recommended pressure.

In equatorial regions like in Kenya, you will want to set your tire pressure at an average of 32Psi to 35Psi. At this pressure, you will get proper handling and fuel consumption will be economical.

This tire pressure should be set when the tire is cold. What happens when a tire heats up due to friction between it and the road is that the tire pressure increases due to the friction.
