Chains increase the surface area which increases the friction so you gain traction.
As in automobile tires, the purpose of the tread is to increase traction (friction). They increase the surface area of shoe-to-ground contact.. Further, the tread forces softer ground to mold to its shape, allowing more lateral force to be applied to each step. All this increases the traction between your shoes and the ground and allows better control of movement (allows more applied energy to each step with less slippage).
For better traction.
Because water is a better conductor then skin cells.
Yes, you can use overdrive in your car when driving in the snow. Using overdrive helps the car maintain better traction in slick and icy conditions.
There are many reasons why, and I have really no clue, but i believe sand is important because of beaches. I love beaches! I'm only doing this because I got bored, so don't use this for science.
with traction control on you have better acceleration because the ecu is giving the right amount of power to the wheel with most traction.
Because of better condition
I think you may mean traction? Usually the wider the tires the better. Also racing tires greatly improve cornering because of their soft compound which grabs the road better.If you meant friction... um, I would say skinny tires because it would be easier to "burn out" or lose traction, causing lots of friction.The loss of traction, when talking about cars, will increase the amount of friction and heat.
most tennis shoes are smooth on the bottom and cleats have things on the bottom of them that can stop you when you are moving better
because the weight of the car pushes down on the tire more making it wider giveing it more traction, also it works better if you have flatter tires.
Because of better condition
I don't know of anything that gets better traction on ice than snow.

Better traction because both wheels are receiving power from the engine .
With tracks by far. They are superior to tires for traction.
It means Traction,and traction means better grip on the ground
