Transcript of Winter Tires vs. All-Season Tires

The Basics
What's the difference?
Advantages
Safety
Disadvantages
Tough on roads
: The design of the snow tires, especially the
spikes, causes them to dig harshly into asphalt, causing it to deteriorate faster. Over time, many people with snow tires can create potholes and all sorts of other issues
Comparatively fragile
: Since snow tires are constructed from
softer rubber than regular tires, they wear down more quickly in warm weather.
Cost
: On average, winter tires can cost up to $120 per winter tire.
Depending on the tires, they usually last for 3-5 years, having to be changed twice yearly costs about $75 each time.
False assumptions
: People are under the delusion that it’s safer to
go faster. Always be cautious.
All-season tires
: At 8°C or higher


Snow tires
: At 7°C or below


Recommended
: Do NOT use winter tires all the time. Snow tires are not made for all seasons, just as all-season tires are not made for Winter.
When to use What
The stats
Statistics – car accidents related to winter weather in Canada from TAIS
:

Weather conditions were a factor in 5% of all accidents resulting in death

Over 1,400 accidents included weather conditions among factors

Packed snow or ice was present in over 7,500 accidents, more than 26%

Wet conditions, loose snow or slush were present in nearly 3,500 accidents

Heavy snow was falling during nearly 1,500 accidents

Light snow was falling during over 900 accidents

Sleet or hail was falling during over 175 accidents

Conclusion
Do the costs weigh out the benefits? If you do make it a law that people must use winter tires, where does this law apply? Do you make the laws based on municipality?

The snow-tires are better but not perfect. They don’t protect you, they just better your situation. A life-threatening winter car crash or a new set of tires?

These are all factors in the decision, so now it's your turn to decide. Will you steer clear or dread the tread?

Winter Tires vs.
All-Season Tires

By: Anita and Nhi
The rubber that surrounds the tire and makes contact with the road, providing traction. Grooves are not the tread but are instead called the tread pattern.
Traction:
Traction prevents the car from skidding when you drive forward, turn or stop. Increasing traction is dependent on maximizing friction.
All-season tires:
- made to provide good traction and grip in wet and snowy weather
- designed to provide a stable performance in wet and dry conditions (hence the name ‘all-season’)
- even though all-season tires offer traction in many different weather conditions, winter tires are superior when it comes to traction in the snow and on ice
Winter tires:
- enhance performance of the brakes during snowy & icy conditions
- help the car perform best in all types of winter conditions
- feature the “tread” designs made specifically for intense weather
- use tread rubber so tires stay flexible during low temperatures to maintain better control for the driver
- the tread on the tires reduces the build-up of snow, allowing the car to maintain a grip on the road
- most drivers claim that winter tires ensure a feeling of confidence and control when driving in harsh weather conditions

The outer edge of a wheel, attached to the hub by spokes, holding the tire. It makes up the circular strip of metal forming the connection between the wheel and tire.
Winter
Tires
All-Season
Tires
Designed to provide quiet, good overall performance

Treads have broad large contact with road, with channels made to divert water

Made to provide good use on dry roads

Mud and snow placement based on tread design
Larger grooves and tread blocks to grip the road and prevent slipping

Tiny razor-like spikes made to dig into snow, and a V groove to move slush and water out of the way

Made to maintain elasticity in lower temperatures for better traction

Design based on performance testing
The End.
Thanks for listening!
Better control of car
Better grip
: Softer and grippier rubber, and very deep treads provide snow tires with the most traction possible by preventing snow build-up.
Flexibility
: The softer rubber of the snow tires are constructed with a special compound that allows them to resist hardening and remain more flexible during low outside temperatures.
Superior braking
: All season tires are liable to lock up and skid on icy roads, but with the better grip, snow tires can allow you to break the way you need to.
Comfort of driver
(provides confidence/security)
Less accidents on the road
