This winter I installed 4 Firestone WinterForce tires on my Toyota Camry. The traction in the snow sucked without them, as I have a V6 with much torque! Since installing the tires, the car does seem to not roll as freely,than without them, there is more road noise due to the tread pattern (Agressive), however it goes like a hot knife through butter in the heavy white stuff! The car was downright dangerous without these tires!...I love them, however I am looking forward to Spring, to put the Touring Tires back on & have a quieter ride!.....
