The 2020 ADAC SUV All season tyre test has tested seven all season tyres in the popular 235/55 R17, and include a summer tyre in the dry and wet, and a winter tyre during snow and ice testing.

ADAC usually hides all their data and just gives numeric scores, but this year have released braking distances for all four braking tests. This might be to back up their conclusion from this test, which is even the best all season tyres are deficient compared to a summer and winter tyre combination.

The other thing worth noting, ADAC gives 30% of the score weighting to snow and ice performance, which is ideal for the colder European climates, but less ideal for climates like the UK which see snow once every few years. As always, dig into the data yourself, as  according to these results, the last placed Bridgestone might just be a better all season tyre for the South of England than the other all season tyres in this test. 

Braking

The dry braking test (from 100 km/h) really highlighted why ADAC believes a summer and winter tyre combination is a safer year round option than an all season tyre, as even the best all season tyre still took an extra 6.5 meters to stop the SUV.

The Bridgestone A005 had an impressive advantage when stopping in the wet from 80 km/h. The summer tyre could only place third.

Snow braking from 50 km/h was led by the winter tyre, with Nokian, Uniroyal, Continental and Goodyear all performing well.

Ice braking from 30 km/h again gave the winter tyre a clear advantage.
