Built as a winter tire for light commercial trucks and vans, the Firestone Winterforce LT uses a specialized rubber compound that stays pliable for consistent traction in subfreezing weather. Full-depth tread grooves, open shoulder slots and a dense sipe network add biting edges in snow and slush, so it is ready to work through tough winter weather.
It is also pre-drilled for easy stud installation (where permitted) for extra traction in extreme winter conditions. This LT275/70R18 size is load range E with a 125/122R rating.
