Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use.
Aspect Ratio:
Refers to the height of the tyre expressed as a percentage of the cross-section profile. Hence a 70% aspect ratio refers to a tyre that is 70% as high as it is wide. Also defined as the ratio of the height of a tyre wall to its width. For example, the height of a 70 series tyre is 70% of its width. The lower the ratio, the wider the tyre.
