Cutting The Guesswork From Tire Development

Adhesion Test

How it’s tested
Wheel Energy measures a tire’s straight-on grip by pressing it into a slab of stone or pavement and pulling on it until the tire starts to drag across the surface. By controlling the factors other than the tire that influence grip, Wheel Energy is able to isolate the differences in grip between tires.

What matters?
The test can used to measure grip differences created by tire construction, rubber compound and tread pattern. It can be conducted in wet and dry conditions.

From the lab to the road
This factor is more important for off-road tires than for road tires.
