BRAKING

We varied our approach speeds by driving surface and by season for two reasons. First, this represents how most Canadians would normally drive on that surface in each season. Second, testing in both seasons provides an indication of how a tire's performance will be affected by road temperature.

CORNERING

To understand how road surface temperatures affect the cornering performance of a tire, our cornering tests are completed in both summer conditions (dry and wet pavement, and gravel roads) and winter conditions (dry, wet and icy pavement). Please note that slush is also tested but completed in a specific slush cornering test..

? Independent & Objective Testing

The independent tire testers conducted extensive tests to determine how the tires in our core line-up perform in a range of conditions in both summer and winter. To maintain neutrality, no driver knew the specifics of the tires they were testing each time. All results were analyzed and processed by the testing group and then provided to Kal Tire for sharing with our customers.
