With its mud and snow rating, this tire allows your truck or SUV to perform in even the most inclement conditions. It uses an all-season tread pattern and four circumferential grooves to maintain traction on wet or icy roads. And for extra comfort on pavement, the tire uses 5-Pitch Technology to reduce road noise for a quiet ride.
