I often get asked to do braking tests at different temperatures to see exactly how temperature affects the dry and wet performance of summer, all season and winter tires.
Until recently it's been impossible as you can't control the weather, and even if you started to test at a certain temperature outdoors, the weather would change through the test (it takes about an hour to do 5 sets of tires in braking testing!) Now, thanks to Test World in Northern Finland, we've been able to test summer, CrossClimate, all season, winter and nordic winter tires in dry and wet braking at 0c, 2c, 6c, 10c, 15c! We've also tested the snow performance of all the tires.
The test car is a VW Golf using 205/55 R16 tires. Watch the video for what is a very interesting test, and check out Test World at https://www.testworld.fi/
