Triangle launches the EffeXWinter TW421 tyre

Chinese based Triangle Tyre has introduced its new EffeXWinter TW421, a directional ultra-high-performance (UHP) winter tyre specifically engineered for safety, precision, and comfort in winter conditions.

Developed after “extensive” research and development in Europe, the TW421 combines advanced materials and innovative design to cater for sports cars, premium saloons, and high-performance SUVs.

The EffeXWinter TW421 features a V-shaped directional tread pattern paired with an advanced compound, for superior grip and shorter braking distances on wet, snowy, and icy surfaces. Plus new sipe technology enhances traction in harsh winter conditions, whilst rigid tread blocks improve stability and steering precision.

Additionally, the incorporation of new polymer materials is considered to enable consistent performance across a wide range of temperatures, balancing safety with driving enjoyment.

The EffeXWinter TW421 will be available in 50 size options from 17 up to 20 inches during its initial rollout with the tyre strengthening Triangle’s winter tyre portfolio, and positioning the company to capture growing demand in the premium and performance vehicle segments.
