Winter Tires
Another advantage of physics, was development of winter tires that can improve car's safety during winter time. In winter most drivers in the cold regions of the world change their tires to winter tires these tires help lower the risk of accidents and allow drivers to drive with ease over snow and slush. Winter tires are considered a very positive influence on driving environments, assisting driers in getting a good grip on frozen roads.
With the exception of tires on racing cars all tires nowadays have some form of tread. The tread on a tire effects in a higher friction on the road than if the tire was smooth, this allows drivers to have greater control over the movement of their car. The tread allows water to push into the spaces while the rest of the tire has direct contact with the road. In winter however there is a massive amount of water on roads that flows into the tread design and freezes which then effects in less of the tire surface area in direct contact with the road, which in its turn lowers the amount of friction between tire and road. Winter tires are therefore designed with ridges that direct the snow and water in a way that the high ridges on the tire all have direct contact with the road, which allows friction to occur at the maximum potential of the tire, which prevents the car from skidding and losing control. All of these helps improve car's safety in emergency accidents.
Winter tires however are quite costly and can not be afforded by every person in need of them. The costs vary with the size of the vehicle. There are different types of winter tires in different regions some are only made for slush and snow, some for slightly icy roads as well, and some are even designed with spikes that dig into ice and keep the car from slipping.
