As many may know, I am not a fan of all-season tires for winter driving. I stumbled onto this review on autos.ca. They'd run three identical trucks "on a snow and ice-packed course," two with dedicated winter tires and one with all-season tires. I thought I'd share this quote:
The truck wearing the all-seasons was another story. In addition to its limited ability to gain traction from standstill, these tires exhibited poor grip in lateral and transient maneuvers on this surface. This truck simply wanted to slide sideways when asked to corner, the stability systems almost continuously trying to correct for the loss of control.
Our group’s conclusions were that the General Grabber Arctic LT tire outperformed the Firestone Winterforce LT when accelerating from standstill, and felt more slightly controlled in transient and lateral maneuvers. Both LT tires far exceeded the all-season tire in these conditions, with the General Grabber Arctic clearly superior in the test for traction. [Emphasis mine.]
