N-Rated Tires

Why should you switch to winter tires?

What are the features which distinguish winter tires? The secret lies in the material composition: the rubber on winter tyres does not harden in the cold; their tread patterns deflect water and provide good lateral support. Their tread sipes pick up snow to enable added grip.

One of the most important components of your Porsche vehicle is the tires you purchase. Buying winter tires for driving in the often-severe Alberta winters will give you peace of mind as you travel. When you understand the value winter tires provide, you can make the best decision for your vehicle's performance and your safety.


Proven Performance

The Ministry of Transportation of Quebec conducted a test comparing winter tires to all-season tires to find out whether there is a real difference in performance. In temperatures around minus 20 degrees Celsius, cars with all-season and winter tires traveled at 50/kmh on compacted ice and snow. The result was that when the car with winter tires was braked, its stopping distance was 11.6 metres less than the vehicle with all-season tires.

A similar test was completed by Tire Rack, using a Porsche Cayenne. In an acceleration test, the winter tires made it 200 metres in just over six seconds, compared to the eight seconds it took the vehicle with all-season tires.

Braking was another component of the Tire Rack test. When the vehicles were traveling at 30/kmh, it took the Cayenne with the winter tires just 61 feet to come to a stop, while the Cayenne with all-season tires required 102 feet to stop. This is the equivalent of 2 = car lengths. It is easy to see how using the appropriate, seasonal tires can prevent an accident. 

The N Rated Winter Tire Advantage

The difference between winter tires and other tires comes from the tread compound. When the temperature reaches seven degrees Celsius, the rubber in non-winter tires hardens, which reduces handling and results in longer stopping distances. All-season tires are a middle-of-the-road compromise.

Porsche tests all of their tires before they are sold or installed on Porsche vehicles. They ensure they can support the power and the weight of each model in all road conditions. Once a tire passes rigorous testing, it's given an N rating. Porsche only sells and installs N rated tires, and Porsche models should only have N-rated tires, even if they are different sizes in the front and rear. You can purchase these tires separately from Porsche Centre Calgary or buy a complete, easily-installed alloy rim set, which includes both tires and rims.
