A tire’s tread is the part of the tire that comes into contact with the road. The tread is what provides traction, and it also helps to protect the rest of the tire from wear and tear. There are various tread patterns that can be used on tires, and each has its own advantages and disadvantages. Some tread patterns are designed for better traction in wet or icy conditions, while others are better suited for dry roads. Ultimately, it is up to the driver to choose the correct tread pattern for their needs.
