Key Ring Tread Checker
(Non-calibrated for visual guidance only)
Use the guide at the bottom of the gauge to determine how much tread you have left.
Tyres under 3mm, report for replacement (or regrooving).
Legal Tread Limits
GVW > 3.5T = 1mm
GVW < 3.5T = 1.6mm
Cuts in the tyre reaching the cord
These can’t be any greater than 25mm or 10% of the tyre section width, whichever is greater. If exceeded, report & VOR the vehicle. If less, report for repair.
E.g. 315/70R22.5 = 315 x 10% = 31.5mm
