Tyre pressure: why is it so important?

Keeping the right pressure for your car tires is one of the safest measures while on the road. Maintaining the correct tyre pressure should be a routine exercise for your car. Maintaining the correct tyre pressure is vital to giving your car engine a tune up.

Why is tyre pressure so important

Keeping the right air pressure for your tyres ensures that they take long to wear, saves you fuel costs, and enhances efficient handling of your car so as to prevent accidents through the right grip. Failure to maintain the correct tyre pressure is associated with various negative effects that include poor petrol mileage, bad handling such as loss of control while on the road as the car does not have sufficient grip on the road, and potential vehicle overloading.

Tyres can be associated with the problem of losing pressure even without punctures through a process known as permeation. Usually, tyres may lose up to two kilopascals of air monthly during cool weather, a condition that becomes worse in warmer weather. Besides, car tyres are usually subjected to impacts and flexing that can significantly diminish their air pressure.

Correct air pressure

Having the correct air pressure for your tyres ensures that they last longer. This is because the tyres have the right grip on the road as you drive, unlike over-inflated and underinflated tyres that lack perfect grip on the road and may lead to accidents. Maintaining the right pressure also helps save fuel. Underinflated tyres have the effect of over-weighting the car, making it consume more fuel than required which is a major uneconomical aspect as more fuel is required to maintain the same speed.

The right tyre pressure allows for proper handling in instances such as speeding, negotiating corners and overtaking. This is an effect of the steering problem caused by the under-inflated tyres that raise the chances of rolling resistance. Well inflated tyres have the right grip on the road and thus stability of your car is maintained at the right level.

Underinflated tyres may lead to swerving and veering off roads more often. Failure to maintain the right tyre pressure may also lead to poor gas mileage and reduced tyre life since underinflated tyres experience more weight on the ground and hence more tear and wear of the tyres. Routine tyre checks are therefore the perfect solution for regular tyre pressure maintenance.

Potential problems

Under-inflated tyres are also associated with overheating problems, a condition that increases chances of bursting. Overinflated tyres are also associated with discomforts in driving as they give a bumpy and uncomfortable ride since such tyres reduce the usual surface area of the tyre in contact with the ground which eventually reduces grip, a usually risky case in bad weather. Too much air pressure in your car tyres also increases chances of wear and tear as the tyres are made more susceptible to damages resulting from impacts while driving. Correct air pressure is also vital for breaking while driving. For example, underinflated and overinflated tyres have a relatively lesser grip on the road as compared to well-inflated tyres, a condition that may lead to sliding while braking and hence possible risks of accidents.

However, tyre inflation also depends on some factors that include temperature. Cold weather or winter may reduce your tyre pressure while warm weather and summers may increase your tyre pressure. It is, therefore, advisable to consider weather changes before driving to ensure that your car tyres are maintained at the right pressure to minimise chances of such negative effects. Keeping the correct tyre pressure also ensures that your tyres wear evenly, assuring a more comfortable ride, better handling on road, and a relatively dependable traction while driving.

It is advisable to keep the correct amount of pressure for your tyres as over inflation and under inflation has various demerits. For example, overinflated tyres are usually stiff and rigid, making the surface of tyres in contact with the ground patch leading to harder rides and uneven tread wear. Under inflation lose their shape and become flatter on the ground, causing premature wearing of the tyres.
