Reading A Tire Sidewall


Tire pressure

Incorrect tire pressure can have serious safety consequences.


Under-inflated tire

An under-inflated tire can result in unstable vehicle handling, and may even overheat and explode. Driving with an under-inflated tire will also reduce the tire’s life expectancy and increase the vehicle’s fuel consumption.


Overinflated tires

When tires are overinflated, only the centre strip of the tire meets the road surface. Since surface contact is reduced, the tire’s grip on the road is weaker. Of course this causes road handling problems—the vehicle will respond differently to direction changes and is harder to stop.


As well as making driving rougher, high tire pressure causes more wear on the steering and suspension parts and cuts down on a tire’s useful lifespan.


Recommended pressure

Atelier de Pneus Réal Chicoine therefore recommends that you check the air pressure in your tires -or have it checked- every month, and always follow the recommended pressure provided by the vehicle manufacturer. The job is easily performed with a tire pressure gauge, and takes just a few minutes.


Check the recommended tire pressure label, usually found on one of the vehicle doorframes, in the glove compartment, on the fuel tank access door or in the owner’s manual. Following the recommended pressure is important because the manufacturer of your vehicle has determined that at a given pressure—taking into account vehicle weight and other characteristics—stability, road handling, load capacity and fuel consumption will be optimal.


Don’t forget to also check the air pressure in your vehicle’s spare tire.
