Focus: Standard

The largest and best-selling category, and Triangle EFFEXWINTER TW421 belongs to it. No single property is pushed here at the expense of the others — comfort, grip, noise and tread life keep a sensible balance. For most drivers it is the safest bet: the tyre behaves predictably in the dry and in the wet and covers a decent number of kilometres.
