There are many myths, and confusion, about whether it is good to run your tires above or below the recommended pressure. The majority are uncertain, since it is best to comply with the manufacturer’s requirements for each model. It must be borne in mind that the wheels are the only link between the vehicle and the road and, for this reason, it is very important that they are in perfect condition and, to achieve this, it is essential that they have the right pressure. |
Norauto lists how incorrect pressure can affect driving. First of all, it should be noted that there is no adequate pressure for all vehicles and tires. The ideal pressure for each tire is given by the vehicle manufacturer itself and is usually found in the car’s documents, on the front doors of the car in question, in the glove compartment or on the fuel cap.
Of course, it should also be known that the pressure varies depending on the weight and that the same pressure should not be carried if the vehicle is empty or loaded. Also, the front tires may carry a different pressure than the rear tires.
Effect of incorrect pressure
– If the tires do not have the correct pressure, you could lose control over the car. Stability, braking distance and braking itself are altered.
– Comfort and ergonomics are reduced. The tires absorb potholes worse.
– There is a greater possibility of tire blowout.
– If you have excessive pressure, the surface of the tire that is in contact with the road is reduced and therefore the grip decreases.
– The tires wear more and irregularly, which reduces their useful life.
– There is a higher fuel consumption and, therefore, a higher pollution, especially with low pressure.
– The car reacts worse to possible unforeseen events and in certain manoeuvres: turns, changes of direction, curves…
Keep in mind that newer cars may have tire pressure monitoring systems. In these cases, any variation in pressure in the on-board system is usually reported.
