The Triangle EffeXWinter TW421 is a directional ultra-high-performance winter tyre designed for sports cars, premium saloons, and high-performance SUVs. This winter tyre features a V-shaped directional tread pattern combined with advanced compound chemistry and innovative sipe technology to enhance traction on snowy, icy, and wet surfaces. The tyre delivers strong dry braking performance with a notably quiet noise level of 70.3 dB(A), though handling stability in dry conditions remains limited. In wet conditions, the tyre provides surprisingly good braking performance ranked second overall in testing, though grip remains limited. On snow, performance is average with reduced confidence and unstable transitional handling. The tyre is available in 50 sizes ranging from 17 to 20 inches, with load indices varying by size and speed ratings up to V (149 mph). This budget-conscious option suits drivers seeking affordable winter performance, though durability is shorter than premium alternatives.
