Asymmetrical tyres have a tread pattern that is different across the width of the tyre. When looking at an asymmetrical tyre the inner and outer tread patterns will not be the same.

Asymmetrical tyres are designed with vehicle performance in mind and are commonly found on sports cars. Asymmetrical tyres have large blocks of tread on the outside to increase cornering stability and narrower blocks of tread along the inside of the tyre to aid winter or wet weather driving. They are also known for their low road noise.
