Tyre Tread is that part of the tyre which is in contact with the road directly. Normally, these are made of thick rubber to provide high level of traction so that it does not wear away quickly. However, with the regular usage of tyres over a period of time, the tread will wear off which results in ineffective traction and it could be retreaded. Though the word tread is used to denote the pattern of grooves on the tyre, but the grooves are not treads. The distinction becomes more important in racing cars that has a tread but not a pattern. Generally, the treads or grooves are used for removing the water from the tyres. Lugs are also found on the tyre which is non-symmetrical and helps in minimizing the noise.
