Making Sense of Tires
Need help understanding the information on your tires?
Here are some basics to identify and select the right tires.
The first letter (only found on certain tires) indicates the vehicle type. P stands for passenger vehicles, and LT refers to light trucks.
The first number tells you the width of the tire tread in millimetres. Usually it will be between 155 and 245.
The second number indicates the height of the tire sidewall as a percentage of the tire’s width. Usually it’s between 45 and 80.
The letter R means it’s a radial tire. If not a radial tire, it will be a bias tire. These two tire types are manufactured differently.
The last number provides the inner diameter of the tire, a.k.a. the wheel’s diameter, in inches.
Tubeless tires don’t have an inner tube. They’re more robust, meaning fewer punctures.
The snowflake symbol means that it’s a winter tire that meets performance requirements for traction in the snow. The M+S symbol means the tire meets the Tire and Rubber Association of Canada’s standard for use in mud and snow. This designation can be found on winter and all-season tires. However, the tire performance is not actually tested in winter conditions.
The last figure is a number and a letter. The number indicates the tire’s load capacity. This number is an index and not the actual maximum weight. The letter next to it is the tire’s speed rating. The manufacturer assigns this rating to indicate the maximum speed at which the tire can safely manage heat.
How to Spot Tire Wear
A tire’s lifespan :
Making sure your tires are in good condition is essential to safe driving. Tires usually need to be replaced or checked by a specialist after 4 to 5 years. A 10-year-old tire should be discarded, even if unused, as the chemical composition of rubber degrades with time.
How can I assess the condition of my tires ?
The most common method is to use a quarter. Simply insert the coin between the tire treads with the caribou’s nose facing downwards. If the caribou remains visible, the tires need to be replaced.
Preventing wear :
To prevent the premature wear of your tires, it’s important to maintain the recommended air pressure. This means frequently checking your tire pressure or inflating the tires with nitrogen. Note that your tires should be rotated and balanced every 10,000 km to ensure wear is equally distributed.
