The added surface area allows for more traction and less sinking of the vehicle when in mud or sand.
Amy tanks do NOT have chained wheels. Tanks are tread laying machines.
Install the chains on the drive wheels.
Tanks have interior wheels that drive their treads, which revolve around the outside of the entire set of hub wheels. Light tanks may have road wheels that are fitted underneath, to avoid damaging the surfaces of roadways and bridges.
The primary drive wheels are the front wheels - therefore, those are the wheels that should have the chains placed on them.
You put tire chains on the front wheels of a front wheel drive vehicle. The chains help the tires driving the car get a better grip on the road. Some people put chains on all wheels. That makes the brakes work on all wheels.
the weight of the vehicle pushes the chains down into the ice for added traction
Car chains are designed to aid the motion of the car during ice and snow. Therefore, they should be attached to the drive wheels of the vehicle. In other words, front wheel drive cars need the chains attached to the front wheels.
it prevents skidding in deep snow
Rear, since they are the Drive Wheels when using Two-Whee Drive.
Cable tire chains are also known as snow chains, they are devices fitted onto the drive wheels of vehicles to provide friction or traction while driving through snow or ice.
caterpillar tracks have large surface area than wheels. larger the surface area, smaller will be the pressure. Hence tanks and buldozers are fitted with caterpillar tracks
They're called threads, and they are used because they work where wheels would bog down (like mud and sand).
