Why Does Tyre Pressure Change?
Tyre pressure (psi) is influenced by a variety of factors including normal air loss through the tyre, payload, temperature, and damage to the tyre. Tyres will naturally lose 1-2 (psi) per month due to regular wear and tear. Additionally, tyre pressure changes with ambient temperature – about 1 (psi) for every 10-degree change in temperature.
When is the best time to check my tyres?
There is not a specific time of day to check your tyres, but, as mentioned above, you should only check them when they are cool.
Problems with Overinflation
If a tyre is overinflated, it will become stiff and rigid and the rubber that contacts the road (Footprint) will be greatly reduced. This will decrease your ability to control your car and puts the tyre more at risk of damage when coming into contact with potholes or debris on the road. A tyre that is overinflated is also more at risk of an explosive flat tyre due to the excessive air pressure. If your tyre pops it can cause massive control issues which could possibly lead to an accident.
Problems with Underinflation
An underinflated tyre can cause numerous problems for a vehicle. The first is that the tyre will lose its form and there will be an increase of rubber meeting the roadway, which can reduce the life of a tyre by as much as 25%. Other major issues with underinflation are a reduction in fuel economy by 5 percent or more due to the extra engine power needed to turn the soft rubber. Finally, you will deal with a lack of vehicle control. A properly inflated tyre will allow for precise cornering and handling, low tyres will end up causing a bumpy, uncomfortable ride.
Proper tyre inflation means that you will have the better control of your vehicle and higher fuel efficiency. To ensure your car’s tyres are properly inflated, find out what the recommended PSI is and then use a quality air pressure gauge to measure it from time to time.
Most fuel stations have air hoses that allow you to quickly put air in the tyres – get a check.
