Tire Tread and Tire Track Evidence

What is the difference between tire tread evidence and tire track evidence?

• Tire tread evidence deals with the design and dimensions of an individual tire, while tire track evidence refers to all of the tire patterns created by the car as a whole.

• Tire tread evidence refers to all of the tire patterns created by the car as a whole, while tire track evidence deals with the design and dimensions of an individual tire.

• Tire tread evidence and tire track evidence are the same thing.

• Tire tread evidence and tire track evidence are unrelated to each other.

What can be analyzed from tire treads?

• Tread design, noise treatment, tread wear features, and any other individualizing characteristics

• Tire track width, wheelbase dimensions, turning diameter, and the relative positions of tracks

• Tire patterns and the dimensions of an individual tire

• The type of noise treatment and the tread wear indicators

What are tread wear indicators?

• Raised bars of rubber that indicate how much a tread has worn down

• Sections of tire tread that come in different sizes

• Design features that make up the pattern of the tire

• The measurement made from the center of one wheel to the center of the opposite wheel

What is the purpose of noise treatment in tire treads?

• To reduce noise by creating a variety of pitches with differently sized tread blocks

• To increase noise by creating the same pitch with all tread blocks

• To indicate how much a tread has worn down

• To determine the dimensions of the suspect car

What can be determined from tire tracks?

• Tire track width or stance, wheelbase dimensions, turning diameter, and the relative positions of tracks

• Tread design, noise treatment, tread wear features, and any other individualizing characteristics

• The type of noise treatment and the tread wear indicators

• The design features that make up the pattern of the tire

Which measurement is taken from the center of the hubs of the front wheels to the center of the hubs of the rear wheels?

• Track width or stance

• Wheelbase

• Turning diameter

• Tire positions

How can the turning diameter of a vehicle be calculated?

• Using the equation B squared divided by a plus a

• By measuring the distance between two points on the turn circle

• By measuring the distance between the outer margin of the circle and a midpoint between two points on the circle

• All of the above

When are all four tire tracks visible?

• When a vehicle moves in a straight path

• When a vehicle turns

• When a vehicle is parked in snow or rain

• When a vehicle undergoes stress from the load or weight

What is the importance of documenting tire positions?

• To determine the dimensions of the suspect car

• To reduce noise by creating a variety of pitches with differently sized tread blocks

• To pinpoint the exact section of tire tread that made the impression

• To interpret the sequence of events of an accident or crime scene

What can tire tread and tire track evidence help with?

• Matching tire tread marks from an accident or crime scene with a tire from a suspect vehicle

• Determining the dimensions of the suspect car

• Reducing noise by creating a variety of pitches with differently sized tread blocks

• Analyzing the design features that make up the pattern of the tire
