What are worn winter tires capable of

They must be capable of something, right?

Yes, but let's break it down in more detail.

The Hungarian edition of Autonavigator tested several models of all-season tires and compared them to worn-out summer and winter tires. Unfortunately, the degree of wear is not specified, but by default, we will consider it to be the maximum allowed: summer - 1.6 mm and winter - 4 mm.

We will compare the results relative to the leader in each individual discipline.

🪨 Braking on dry pavement (from 60 km/h)
Leader - 14.5 m
Worn-out summer tires - 15.9 m
Worn-out winter tires - 17.8 m

💧 Braking on wet pavement (from 60 km/h)
Leader - 14.1 m
Worn-out summer tires - 16.0 m
Worn-out winter tires - 17.3 m

🧊 Braking on ice (from 40 km/h)
Leader - 18.5 m
Worn-out summer tires - 77.1 m
Worn-out winter tires - 21.3 m

Another demonstration that driving on tires close to the wear indicators is unsafe.
