Winter tires: useful information and tips

Winter tires: useful information and tips

Without a doubt, winter is coming! SSQ Insurance has prepared a short quiz to test your general knowledge of winter tires.

True or false?

Winter tires can improve braking distance by 15%.

False. Using winter tires can improve your braking distance by up to 25%.

The treads on winter tires are 30% deeper than those on all-season tires.

True. These treads give tires a better grip and road adherence, by evacuating snow and slush.

The law regarding the mandatory use of snow tires between December 15 and March 15 has an impact on my automobile insurance.

True. The purpose of the Highway Safety Code is to reduce the number of accidents. Your insurer may consider that there is an increased risk if you do not install snow tires during the period that you are required to.

All-season tires will lose their elasticity at –20 °C, while winter tires will do the same at about –30 °C.

False. All-season tires begin to harden at –15 °C, compared with –40 °C for winter tires.

You can use a 25¢ coin to measure the depth of the treads in your tires to see if they are worn.

True. Put the caribou’s head upside down. If the tread doesn’t reach the animal’s nose, your tire will be less efficient in deep snow. Do this test in several different places on each tire to get a good idea of their general wear and tear.

Used winter tires can be used during the summer.

Partly true.There is no law that prevents you from using your winter tires in the summer. However, it is not recommended to do so because the type of rubber used in winter tires is more pliable in cold weather (this helps them stay sticky), but using them in the summer could have a negative impact on braking and road driving.
