Tyre type on the Basis of Tread Pattern

Symmetric Pattern
Symmetric tread design can be commonly seen on the tyres of many cars. As their name itself indicates, symmetrical pattern refers to those treads which feature similar continuous design across the tread on either sides of tyre.
Tyres with this type of pattern are normally non-directional, meaning that they can be fitted without worrying about a specific rotational direction.










Asymmetric Pattern
Exactly opposite to the symmetric tread pattern - asymmetric tyre treads feature dissimilar designs on both the sides. This discrepancy in their design allows better grip on flat out roads and also while making turns.
Generally, the outer area of such tyres has broad design where as the inner carries smaller independent tread blocks, as seen on symmetric design.










Unidirectional Pattern
The unidirectional (also known as directional) tread patterns are made to perform well when fitted on a specified direction, this direction is generally marked with help of an arrow on the sidewalls.
This type of tyres have 'V' shaped tread design which helps increasing aquaplaning resistance when the vehicle is running on high speeds, by efficiently cutting it through this unique pattern.
