The Firestone Winterhawk 4 22545R17 91H is a winter tire built for passenger vehicles, with a section width of 225 mm, an aspect ratio of 45%, and a fit for 17-inch wheels.
With a 91 load index (up to 615 kg / 1356 lbs) and a H speed rating (up to 210 km/h / 130 mph), this tire falls into the C1 class, aimed at drivers looking for solid performance without a premium price tag.
No rim protection is built in here, meaning the wheel edge isn’t specifically shielded from curb contact. It does not offer run-flat capability, meaning a puncture will require a stop rather than continued driving. This is a standard-build tire rather than a reinforced one, in line with typical load needs for passenger vehicles.
The tread is designed to handle mud and snow, and it’s been validated for winter conditions.
On the EU tire label, it scores a D in fuel efficiency, B in wet grip, and B in rolling noise, with a measured noise level of 71 dB — neither notably quiet nor loud.
Keep in mind the EU label doesn’t capture everything — dry-road handling, aquaplaning resistance, and wear rate aren’t part of the official rating, so it’s worth weighing alongside fuel efficiency and wet grip.
