9. Taking care of upon Ice II
This running look at which is executed upon an icy appear actions a tyre’s optimum grip within curves with substitute radiuses and upon a extensive straightaway. Tyes are evaluated based mostly upon sizes and try out motorists’ viewpoints. Ice-coated keep track of: 900 meters.
