Underinflation causes poor handling, fuel inefficiency, and an increased risk of tyre failure. Tyres are routinely exposed to stress and impacts that can reduce air pressure. Sometimes a small nail, screw, or other objects can puncture your tyre and act as an inefficient plug. This could cause the tyre to gradually lose air at a rate that you might not even notice. Your tyres also continually lose pressure due to permeation, a natural process where the air escapes from the tyre’s solid rubber sidewall. Weather can affect inflation pressures as well. Your tyre pressure will be reduced by about 1 psi for every 10-degree drop in the weather.
Can increase rolling resistance
Increase fuel consumption – due to the rolling resistance, which makes the engine work harder
Creates uneven tread wear – the edges of the tyre wear out faster
Affect braking performance
Overinflation causes tyres to suffer adverse effects, including a harsh ride, poor handling, and irregular wear. Overinflation occurs when tyres are inflated with pressure exceeding the recommended PSI. Some drivers may even mistakenly overinflate their tyres after reading the maximum pressure listed on the tyre sidewall. This number represents the tyre’s maximum pressure, not the vehicle’s recommended PSI range. Remember to always check the owner’s manual or tyre placard for your vehicle’s correct tyre pressure.
Have a smaller contact area with the road.
May effect breaking
Create uneven tread wear – the centre of the tyre wears out faster
Creates an unpleasant ride – the tyre is unable to ‘soak up’ the bumps
Maintaining tyre pressure may seem like a low priority in our busy daily schedules, but keeping the correct air pressure in your tyres is an important part of vehicle maintenance, as it helps with:
Optimizing tyre performance
Improving fuel economy
Improving handling and performance while driving
Maintaining steering response
Improving cornering ability and stability
Improving steering precision
