Is it economical to keep winter tires on in summer?

Can you keep winter tires on in the summer?

Yes, but!

Saving money is usually the primary motivation for keeping winter tires on during the summer. But it's not always the most economical choice.

And while saving a tire installation in the spring may be worthwhile, it may not be the safest choice when winter arrives.

Let’s explain!

Winter and summer tires: an unattractive mix

Winter tires have a much softer rubber compound than summer tires.

In fact, winter tires have a softer compound for better grip on ice. As a result, they wear out much faster on dry, hot roads.

The effectiveness of winter tires decreases with resistance to movement. This increases fuel consumption, or electricity consumption in the case of an EV.

6/32 a number to remember

In North America, tire treads are measured in 32nds of an inch. A winter tire leaves the factory at around 11/32 to 14/32. A summer tire is between 9/32nd and 10/32nd. They are therefore "thinner".

Generally speaking, a winter tire is "at the end of its useful life" from 6/32nd. It is therefore in its last year of safe use for someone who drives normally.

It's possible to keep a winter tire on during the summer, but this could mean faster wear. They will probably be unusable in the coming winter conditions.

However, if you plan to buy new tires in the fall, it may actually be economical to keep your winter tires over the summer.

Are winter tires safe in summer?

It's important to remember that, while winter tires can be used during the summer months, they are less effective at evacuating water. Driving in the rain must therefore be adapted to avoid aquaplaning.

Driving on winter tires in summer can be a way of saving money. In this case, your tires must be at the end of their useful life. Otherwise, their wear will be accelerated. Be smart!
