Types of Tyre Marks

In traffic crash investigation and reconstruction tyre marks are very importance piece of evidence as each of them is produced by a specific action of the vehicle during the vehicle collision. Tyre marks can provide indication about what a driver did or attempted to do prior to and after a collision. In general, a tire mark is  marks left by a tyre, whether rolling or locked. Tyre marks can be categorised into different types based on the mark patterns and characteristics. Different types of tyre marks are describe as follow:

Tyre marksCharacteristics
Skid marksFormed when vehicle was braked suddenly and locked the wheel
Yaw marksMade by a tire that is rotating and sliding sideways parallel to that wheel’s axle; also referred to as sideslip or critical-speed scuff marks.
Scuff marksMade by a rotating or yawing vehicle, a vehicle acceleration, or a flat tire.

A tire mark from a wheel that is both rotating and slipping: acceleration scuffs, yaw marks, flat-tire marks.
Scrub marksLeft by a wheel locked due to damage.

A skid mark caused by the vehicle being redirected as a result of a collision; marks generally look like irregularly shaped smears and are characteristic of the point of impact.
PrintsMade by a rolling tire.
FurrowCaused by a sliding, non-rotating wheel creating a plowed depression in soft material so that material furrows on each side; no tire print is visible.
RutCaused by a rolling tire in soft material; the tread pattern is usually visible.
Acceleration marksTypical scuff mark made when sufficient power is supplied to the driving wheels and at least one-wheel spins on the roadway surface; begins as a J- shaped mark, caused by initial fishtailing as the tires heat and seek traction; the beginning of the scuff is usually very dark, and the mark gradually disappears.
