STRAßENVERKEHR Winter tyre test 2024 235/55 R18 very good Ranked #4 of 10Finishing 4th out of 10 competitors, the Pirelli Scorpion Winter 2 received a final rating of 'Very good'. It excelled with good snow launch traction and corner grip, very balanced wet performance with short braking distances, and comfortable rolling. The tire also provided high steering reserves in dry corners. It was particularly outstanding in categories like aquaplaning (longitudinal), dry handling, dry lane changes, lateral guidance on snow, snow traction, and wet braking. However, it showed a slight tendency to oversteer during load changes in quickly-driven dry corners and had higher rolling resistance.
