Drivers facing treacherous winter driving conditions should pay close attention to the tires on their
car. Efficient traction becomes more important for safety when driving through
bad weather conditions. Be aware of the pros/cons when comparing the use of
winter tires versus all-wheel drive.
Benefits of winter snow tires
Consumer tire testing is frequently conducted in
Scandinavian countries on test tracks that lie north of the Arctic Circle. If a
winter tire product can perform well under those extreme conditions, experts
agree that consumers should choose similar tires for added safety, especially
if they drive through extreme winter weather conditions. While there are
pros/cons for winter tires, the traction pros outweigh any cost-savings if you
don't have them. When you suddenly find yourself sliding across a sheet of ice
while driving, your car can stop up to a full car length sooner if you have
winter tires than if you have all-season tires.
Pros/cons of all-wheel drive (AWD)
An AWD vehicle distributes more torque to tires and gives
the most traction to all four wheels when needed. This means your tires slip
less and your vehicle has better acceleration. This feature benefits
performance and should not be confused with a safety feature. Many AWD drivers
prefer the cost savings when using all-season tires during winter. What they
don't realize is that an AWD vehicle might offer less chance of tire slippage
when power is applied, but this feature can mask the seriousness of an icy
surface. AWD owners often find themselves in ditches because they
under-estimated the road's slippery conditions and their tires didn't have the
traction needed to help.
Do I need winter tires if I have all-wheel drive?
If you drive your AWD through extreme winter weather, the
answer is "yes." Winter driving safety is not determined by vehicle
acceleration, but by the traction of your tires. The better traction you have,
the shorter the stopping distance. Most consumers don't realize that tire grip
is but one function when tire tread meets the road surface. Quality grip is
determined by your tire tread rubber compound construction and how this
material reacts during cold temperatures, wears with age, size of grooves in
the tread, and tire air pressure when your AWD comes in contact with a patch of
ice.
Quality traction should always be your priority when it
comes to safety. Engine power needed to push through slippery roads won't give
your vehicle any more "gripping" traction when you need it most.
