The beginning of movement & acceleration of any vehicle in snow, ice &
other adverse cold weather conditions is highly dependent on the traction
qualities of the tires on the driving axle. The controlled handling & braking
of a vehicle after it is in motion in adverse weather conditions, however, is
highly dependent on the traction of the rear tires. Consequently, the rear tires
of any vehicle must have equal or higher traction capabilities than the front
tires for safe vehicle operation.
Because of the higher traction qualities of studded snow tires under most
winter weather conditions, installation of only two studded snow tires on the
front of any vehicle (especially front wheel drive vehicles) without two studded
snow tires on the rear can cause adverse (unsafe) handling characteristics.
Consult tire manufacturer for correct stud size. If you sell and/or install
studded snow tires on vehicles you must follow the procedures listed below:
