Good tire tread, weight on the tires (increased ground pressure), traction control systems (typically either all wheel drive or an electronically controlled limited slip differential).
NASCAR tires do not have tread because the cars do not drive on a wet surface. Tread helps channel water away from the surface of the point where the rubber meets the road. Since NASCAR does not race in the rain, a smooth tire gives more surface for the tire for the most traction and speed.
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).
Hydroplaning is the situation which occurs when a vehicles is traveling on a wet surface and the tread depth and design of its tires is insufficient to channel and expel enough water for the tread to make contact with the pavement. At that point the water gets between the tire and the pavement and the car loses traction and control, or hydroplanes. .
For traction and to prevent hydroplaning on a wet road.
There's a great misconception about tires that says tread equals traction. While it's true on wet roads and dirt, it is not true on dry, clean pavement. Rubber gives traction, not tread. The function of tread is to cut through water, dirt, etc by channeling it into the spaces between the tread blocks to allow the rubber to meet the driving surface. This is not needed on a clean, dry race track, and tread merely reduces the amount of rubber that meets the surface and thereby reduces the contact patch. Racing slicks have no tread and therefore give far greater traction by increasing the area of the tire's contact patch on clean pavement. However, in the wet they become virtually useless because the tire can no longer make contact with the racing surface; hence "rain tires" and off-road racing tires have tread.
In ideal conditions, dry weather, great road surface etc. slick tyres offer more rubber to the road therefore greater traction. Normal road tyres are a compromise, on any one trip your car may have to cope with sunshine, rain, sleet, snow, bad road surface, smooth surface, mud, and gravel. Manufacturers have to make a tyre that can cope with that. The result is the tyre on your car.
If you are looking for good track running shoes, be sure to check the tread based on what surface you are going to be running on. If your idea of track running is on a rubber track then you will want a tread that is shorter. For a shale track you will want something more like a cross trainer in order to get some traction with the running surface.
Loss of traction poor tread depth on tires
Tread not designed for traction in snow.
Yes, the type of tread does affect the way it moves over carpet. Other affects the tread could have is speed, traction, exc.
um... the tread
