Snow chains also known as tire chains are devices fitted to tires or vehicles while driving through snow or ice, to provide maximum support to tires. Snow chains attach to the wheels or special systems that deploy chains that swing under tires automatically. These tire protectors which are sold in pairs need to be purchased to match tire size and width. Few chain models can be adjusted to fit various sizes of tires. These handy tools reduce fuel efficiency and also reduce the maximum speed of a vehicle (50km/h).
Snow chains provide traction and braking on snowy or icy surfaces where use of Rhino Roof Box is suggested to protect gears and belongings from snow. Some regions allow use of such chains while few restrict their use because chains could deteriorate road surface. This chain requirement varies from dual tyre to 4 wheelers to heavier vehicles. Generally people go for chains fitted only to the front wheels, but signage and conditions could demand for chains to all tires of vehicles.
There are few cases when chains can fail, they include:
- Driving too fast with chains
- Driving on dry roads for too long period, could also cause vehicle to slide when breaking.
- Not securing the chains too tightly. Tightening of chains need to be checked from time to time while driving in snowy region. A loose chain can be tightened or removed before it wraps around the axle.
- Installing chains on non-drive wheels
- Accelerating too fast causing tire spin and pressure on chains
- Chain break could lead to slapping around the wheel well and wrap around the axle and severe break lines.
Tire chains are available in a variety of types that have different disadvantages of cost, ride smoothness, traction, durability, ease of installation and recommended travel speed.
