Beware winter tires in summer

We are led to think that the majority of these accidents are caused by snow and ice. However, approximately 31% of all road accidents are caused when the pavement is soaked with rain! In Quebec, we begin to feel a “boomerang effect” from the amendment of the Code de la sécurité routière in 2008 that forced the mandatory use of winter tires for all. Several experts have also observed the tendency to drive with winter tires throughout the summer season.

You will be surprised to learn that driving with winter tires during the summer increases the braking distance by an average of 15 to 20%. Moreover, we note that drivers are often inclined to keep their tires up to legal wear limit (the famous 2/32 inch or 1.6 mm of thickness). Knowing that a summer (or all season tire) is designed to be replaced at 5/32 inch, it is not surprising that the high number of accidents during the summer is due to the use of tires winter and summer tires below its theoretical limit of efficiency.

Don’t forget, summer or winter, braking distances are more important than the way you’re going forward. Does the law for the summer tires will be introduced shortly? No one knows. But, the insurances companies are increasingly aware of the consequences of driving with winter tires in summer. When a traffic accident takes place, no one wants to have problems reimbursements of his insurance company!

Last important point, fuel consumption. Rolling resistance is a term increasingly used by tire companies. A tire with low rolling resistance can improve the average fuel consumption of a vehicle until 3L/100km.
