Much like a great pair of winter boots, snow tires are designed to improve traction and handling in slippery conditions. While all-season tires are also known as “mud and snow” tires, they’re not meant for use in the types of heavy snow conditions Canadians face each winter. In fact, winter tires are mandatory in Quebec because of the heavy snowfall they receive every winter. Even if you have a vehicle with four-wheel drive, anti-lock brakes or electronic stability control, your tires still need to grip the road for these features to do their jobs properly. Cutting corners cuts safety Some drivers choose to put snow tires only on the front, thinking it will give them added traction for less money; however, this actually causes a serious safety hazard. Tires ensure efficient braking as well as traction, but your car needs equal distribution of both to avoid spinning out. If you have snow tires only on the front of a front-wheel drive vehicle, the back end can easily slide off course. You wouldn’t wear one boot and one running shoe to walk in the snow; in the same way, your car needs four tires of the same type, size, speed rating and load index for a safe, smooth ride. Mixing tires with different tread patterns, internal construction or size can lead to serious stability and safety issues. Tips for buying Always purchase the right size and type of tires for your vehicle to ensure your safety and maintain your warranty; check your vehicle owner’s manual for the manufacturer’s recommended tire size or speak to your automobile dealer. The two main features to look for are tread design and type of rubber compound.
Look for tires that will best match the road conditions you will drive on most often. If you frequently drive on unplowed roads or in hilly areas, you may want to consider studded tires for additional grip. Check with the transportation ministry in your area to find out if studded tires are allowed, and when you can use them. What about tire chains? In the more mountainous and snowy areas of Canada, tire chains are not only a good idea, but also a requirement. In certain designated areas, you are required to use winter tires, plus carry chains in your vehicle and be prepared to install them. Signs with a flashing amber light indicate that you can’t safely proceed without the chains installed. To use tire chains correctly, fit them closely to the tire and ensure the links are not twisted. Avoid driving over 50 km per hour or on bare pavement, and be sure to change the chains when they become damaged.
