Description
Live winter to the fullest
- Excellent wet braking
- Improved snow traction*1
- Outstanding performance on snow
- Shorter stopping distance vs predecessor *2
Make the most out of winter with the Firestone Winterhawk 4. This new generation winter tyre provides optimal control and handling in cold and unpredictable conditions. Designed for a safe and cost-efficient ride, the Winterhawk 4 will keep you in control on winter roads. The tread pattern relies on unique sipes, grooves and angular edges to attain traction on snow, while the innovative compound and tread design help the tyre stop 4% faster on wet roads than its predecessor.

Manufacturer information
EU Tyre Label
The Tyre Labelling Regulation determines the information that must be provided with regard to tyres' fuel efficiency, wet grip and external rolling noise. Information is also provided on the product's performance in wintery driving conditions.
Regulation EU 1222/2009, which has been in force since 01/11/2012, has been revised and will be replaced from 1 May 2021 by Regulation EU 2020/740, from which point new standards will apply. The assessment categories for fuel efficiency, wet grip and external noise have been changed and the layout of the EU label has been changed accordingly. The manufacturers' product data sheets, stored in the EU database, can be downloaded via a QR code integrated into the label. It also includes information on snow grip and ice grip for tyres that meet these criteria.
The following tyres are exempt from the regulation:
- Tyres designed to be fitted only to vehicles registered for the first time before 1 October 1990
- Remoulded tyres (until Regulation EU 2020/740 has been widened accordingly)
- Professional off-road tyres
- Racing tyres
- Tyres with additional devices to improve traction, e.g. studded tyres
- Temporary-use spare tyres (T-type tyres)
- Tyres with a speed rating below 80 km/h
- Tyres with a nominal rim diameter of 254 mm or less and 635 mm or more

Overview of criteria and valuation classes
Test results
Strengths:
Easy to control with very good driving dynamics, high grip level and generous reserves on snow. Balanced curve dynamics dry at reduced level
Weaknesses:
Weak braking and little grip reserves, also sensitive to load changes in the wet, increased risk of aquaplaning. Long braking distances even on dry surfaces. Audible rolling noise inside, weak comfort
Conclusion:
Dynamic snow specialist with deficits in wet and dry
