The 2018 Auto Bild SUV / 4x4 winter tire test has used an Audi Q5 to test ten 235/60 R18 winter tires, with the Goodyear UltraGrip Performance Gen-1 SUV proving to be the best tire on test thanks to a balanced all-round performance.
Surprisingly Pirelli edged out Continental to second place, with a brilliant result for the Pirelli Scorpion Winter. This tire has been on the market a number of years now, and historically hasn't tested as well as Goodyear or Continental, so there must have been and update for the 2018 winter season. The Continental Winter Contact TS850P SUV rounded out the top three, with its only real weakness appearing during the dry braking tests.
The other notable result was the new Achilles W101X. Budget tires like this Achilles historically perform excellently in snow testing, but end up with dangerously long wet and dry braking distances, but in this test the Achilles held its own, finishing second during dry braking and beating the established names of Toyo and Firestone during wet braking. Impressive when you consider a set is nearly half the price of the most expensive tire on test...
Dry
The Pirelli winter tire proved to be the master of dry testing, but still lagged significantly behind the reference summer tire again highlighting the dry penalty siped winter tires bring.

Wet
The summer tires advantage continued in the wet, albeit the gap was smaller. The top three tires overall were all stars of the wet testing, showing how important wet performance is to winter tire testing.

Snow
Unsurprisingly the summer tire was at a huge disadvantage in the snow testing. Continental proved to have the best snow braking, where Nokian was the fastest around the snow handling lap.

The Pirelli bended an excellent dry and wet performance with the lowest rolling resistance on test, an impressive feat!

The difference between best and worst was 15.7% (1.2 kg / t). Over 12,000 miles a year at $3.60/gal, the Achilles Winter 101 X uses about 13 gal ($46) more fuel than the Pirelli Scorpion Winter.

Unusually the summer tire was the quietest on test.

The budget Achilles was by far the cheapest set of tires on test, with the Michelin the most expensive. Sadly Auto Bild didn't include any wear testing, so we can't judge which tire is best value overall.
