I’ve been using these tires for about 2 years on my Clio 0.9 TCe.
Snow & Ice Performance:
Exceptional grip on snow and ice—truly impressive.
Possibly even better than some premium brands in winter traction.
Dry Road Performance:
Mediocre at best. Performs like a standard economical winter tire.
If you don’t expect above-average dry performance, it’s adequate.
Wet Road Performance:
The biggest drawback. Even with a low-powered car like my 90 HP Clio, the tires are prone to slipping.
Braking on wet roads quickly triggers ABS, and cornering is very poor.
Durability:
Very hard compound—wear is minimal even under aggressive driving.
Thick tread contributes to poor wet grip, higher fuel consumption, and more road noise.
Conclusion:
Excellent choice if you drive in northern, snowy regions.
Not suitable for aggressive wet or dry driving conditions.
Overall, this tire excels in snow/ice but compromises on comfort, noise, and wet traction.
