The proper tire inflation pressure for a vehicle is the one specified by the manufacturer. It is usually found on a nameplate stuck at the driver’s door level or in the owner’s manual. Since the recommended tire pressure is different for each vehicle, this information does not appear on the tire itself.
The recommended tire pressure will be indicated in KPA and PSI for front tires, rear tires, and the spare tire. Tire pressure is measured when cold. A tire is considered cold when it hasn’t been driven for more than 2 hours or has been driven at a moderate speed for less than 3 kilometers. Also note that a tire deflates more easily in winter. The condition and tire pressure are elements checked during our used car inspections.
The advantages of having the proper tire pressure for my car
The air pressure in a tire is an important factor for a tire’s grip on the road, in addition to its quality and wear. This is true regardless of whether your vehicle is new or used.
Maintaining your tires at the proper pressure has only advantages:
- better comfort
- better grip on the road
- fuel economy
- uniform tire wear that improves their lifespan
Over-inflating or under-inflating a tire
An over-inflated or under-inflated tire will have consequences on your driving. An over-inflated tire will have poor grip on the road, will wear out more quickly, and will provide less driving comfort. An under-inflated tire will provide instability and difficulty turning, in addition to wearing out more quickly on the tire sidewalls.
When to check your tire pressure?
It is recommended to check your car’s tire pressure at least once a month.
It is also recommended to check it:
- before leaving for vacation or a long trip
- when you hitch a caravan or trailer to it
- when you add a significant load to the vehicle
