Tire Track Evidence

Tire Track Evidence
Tire Track Evidence Includes…
Tire track Width
Track Width (Stance): measurement made from one center of one wheel to opposite center of wheel
Front wheels turning produce unreliable measurements
Rear wheels accurately record turns
Wheelbase dimensions
Wheelbase - measurement of center of hubs of front wheels to center of hubs of rear wheel
Normally these measurements are not present at crime scenes
Turning diameter
Turning Diameter: Diameter of circle a vehicle makes when its steering wheel is fully turned - pertains to front wheels only
Turning diameter is measured by (B2/A) + A, where:
B = distance between two points ( x and x’) on turn circle
A = distance between outer margin and a mid point between x and x’
Relative positions of turning tracks
When vehicle moves in straight path, only rear tire tracks are available
When a vehicle turns, rear and front tires rack separately
Important to understand and document at crime scenes

I have photos of tire tracks that I believe are my neighbors. Someone drove into my yard and knocked down a small palm tree. It was about 3 feet tall and it’s now broken off at the stem. My yard and the surrounding bricks were also damaged. Could you help me determine if the tracks match my neighbors car? Or maybe give me an idea of what resources I can use to reverse look up tire marks? I have pretty clear photos of the tracks because they created mud on a rainy night

Images and knowing the make and model of the tires is also helpful, if you can get close enough... czcams.com/video/ZtFqmHlhLoQ/video.html
