sch.1-sec.52 Tyre tread

A tyre fitted to a motor vehicle must not have cleats or other gripping devices that could damage road surfaces. A tyre fitted to the motor vehicle must, other than at tread wear indicators, have a tread pattern of at least 1.5mm deep in all principal grooves on the tyre in a band that runs continuously— across the tyre width normally coming into contact with the road; and around the whole circumference of the tyre. A vehicle must not be fitted with a tyre that has been treated by recutting or regrooving the tread rubber, unless the tyre was— constructed with an extra thickness of rubber designed for recutting or regrooving; and labelled to indicate the construction. In this section— principal grooves , for a tyre, means wide grooves, other than secondary grooves— usually positioned— in the central zone of the tyre’s tread; or running across the tyre’s tread; and in which tread wear indicators are usually located. secondary grooves , for a tyre, means shallow grooves in the tyre’s tread that may disappear through wear of the tyre. tread wear indicators , for a tyre, means projections within a groove of the tyre indicating the degree of wear of the tyre’s tread.
