Tire
Ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels.
Snow tires are designed for use on snow and ice. They have a tread design with larger gaps than those on summer tires, increasing traction on snow and ice. Such tires that have passed a specific winter traction performance test are entitled to display a "Three-Peak Mountain Snow Flake" symbol on their sidewalls. Tires designed for winter conditions are optimized to drive at temperatures below 7 °C. Some snow tires have metal or ceramic studs that protrude from the tire to increase traction on hard-packed snow or ice. Studs abrade dry pavement, causing dust and creating wear in the wheel path. Regulations that require the use of snow tires or permit the use of studs vary by country in Asia and Europe, and by state or province in North America.
Snow chains
Snow chains, or tire chains, are devices fitted to the tires of vehicles to provide maximum traction when driving through snow and ice.
Alternatives include studded tires, which are snow tires with metal studs individually mounted into holes in the treads; emergency traction devices which may be similar to tire chains but mount around the tire through openings in the rim; and snow socks, which are fabric rather than chain or cable.
Siping (rubber)
Process of cutting thin slits across a rubber surface to improve traction in wet or icy conditions.
Both Bridgestone and Michelin sell snow tires that are siped at the factory, while Saf-Tee Siping and Grooving sells machines that can sipe most standard vehicle tires.
Shiiba, Miyazaki
Village located in Higashiusuki District, Miyazaki Prefecture, Japan.
During this time most locals have to change their car tires to ones equipped with stronger treading (snow tires).
Lions Gate Bridge
Suspension bridge that crosses the first narrows of Burrard Inlet and connects the City of Vancouver, British Columbia, to the North Shore municipalities of the District of North Vancouver, the City of North Vancouver, and West Vancouver.
Trucks exceeding 13 t are prohibited, as are vehicles using studded tires.
Dowel bar retrofit
Method of reinforcing cracks in highway pavement by inserting steel dowel bars in slots cut across the cracks.
The backfilled slots may sometime give an impression that the highway pavements have been milled into grooves especially after the wear of patching material caused by studded tires.
Road surface
Durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway.
In areas with cold climate, studded tires may be allowed on passenger cars.
Winter storm
Event in which wind coincides with varieties of precipitation that only occur at freezing temperatures, such as snow, mixed snow and rain, or freezing rain.
In places where snowfall is typical, such small snowfalls are rarely disruptive, because of effective snow and ice removal by municipalities, increased use of four-wheel drive and snow tires, and drivers being more used to winter conditions.
Nokian Tyres
Nokian Tyres plc (Nokian Renkaat Oyj), headquartered in Nokia, Finland, produces tyres for cars, trucks, buses, and heavy-duty equipment.
Known for its winter tyres, Nokian is the only tyre manufacturer in the world with its own permanent winter tyre testing facility.
Tire rotation
Practice of moving the wheels and tires of an automobile from one position to another, to ensure even tire wear.
More complex rotation patterns are required if the vehicle has a full-size spare tire that is part of the rotation, or if there are snow tires.
