The 2021 Auto Bild Sportscars winter tyre test has tested twelve of the best winter tyres in 245/40 R18 size using a Mercedes C Class, AND have included a summer and all season tyre as reference.
This is exceptionally useful for those of us wondering whether to fit winter or all season tyres for the bigger while size, and for a change Auto Bild named the all season tyre used, it's the Vredestein Quatrac Pro.
There are however some drawbacks to the single reference tyre. The Quatrac Pro is an older patter now, and certainly not the best all season tyre on the market anymore. This means while it was good in the dry, it didn't beat all the winter tyres as you'd expect (the Michelin CrossClimate 2 certainly would have), it struggled in the wet, and if you'd expected it to come last in a group of winter tyres in the snow tests, you're also in for a surprise.
Sadly Auto Bild didn't name the summer reference tyre, but this was unusually good in aquaplaning, and one of the best in the dry and wet.
There were also some nice synergies between this test and the Tyre Reviews Winter Tyre Test, with the Michelin Pilot Alpin 5 and Hankook Winter Icept Evo 3 performing amongst the best in both tests, and the Bridgestone Blizzak LM005 being the wet specialist of the group.
Dry
As in the Tyre Reviews test, the Michelin Pilot Alpin 5 was the best in both dry tests, beating even the all season tyre, but still significantly weaker than the summer reference which was nearly four meters ahead.
The order of results was also the same in dry handling, with the reference summer tyre leading Michelin and the all season Vredestein Quatrac Pro, with the Toyo SnowProx S954 in fourth.
Wet
Wet braking retained the summer tyres advantage, but this time the gap was closer at two meters shorter stopping distance. The difference between the best and worst winter tyre was fifteen meters from 100kph (62mph) which is a vast difference.
The Bridgestone Blizzak LM005 managed to edge out the summer tyre around the wet handling lap.
The summer tyre regained its lead to be the best in straight aquaplaning, leading the best winter tyre by quite a margin.
Snow
Snow braking once again had the BF Goodrich gForce Winter being the best winter tyre on snow, leading the consistent Hankook Winter Icept evo 3 and Dunlop WinterSport 5.
BFGoodrich continued its advantage during the snow traction test.
Snow handling rounded out the trio of wins for BFGoodrich, while the Nankang SV2 and Toyo Snowprox S954 continued to perform poorly in all snow tests.
Environment
The BFGoodrich was also the quietest tyre on test, with the Nexen WinGuard Sport 2 following closely. In this test, every winter and all season tyre were quieter than the summer tyre.
The Bridgestone had the lowest rolling resistance on test, beating the summer tyre. The all season tyre finished midpack.
There was a difference of 270 euros between the cheapest and most expensive tyres, and as always, the cheapest were amongst the worst performing on test.
