Product Introduction
Tire depth tread scale (also known as tire tread depth gauge) is a precision tool specifically used to measure the depth of tire tread patterns, and is an essential equipment for every car owner and maintenance technician. This compact and practical tool can help you accurately grasp the condition of tire wear and ensure driving safety.

main features
High precision measurement: typically accurate to 0.5mm or 1/32 inch, ensuring reliable measurement results

Durable Material: Made of high-quality stainless steel or high-strength plastic, it is durable and long-lasting

Portable design: compact in size, easy to fit into glove boxes or toolkits

Dual standard scale: simultaneously marking both millimeters and inches to meet different needs

Simple and intuitive: No need for batteries or complex operations, ready to use immediately

Why is it necessary to measure the depth of tire tread patterns
Tires are the only components that come into contact with the road surface, and their condition directly affects driving safety. Insufficient tread depth can lead to:

Significant increase in braking distance (especially on wet and slippery roads)

Reduced vehicle handling and increased risk of skidding

The probability of tire blowouts has significantly increased

May violate traffic regulations (most countries require a minimum pattern depth of 1.6mm)

Regularly checking the depth of tire tread patterns can help you:

Timely replacement of worn tires to prevent accidents

Reasonably plan tire replacement time to avoid unexpected expenses

Maintain optimal fuel efficiency (worn tires increase fuel consumption)

Ensure that vehicles are legally on the road

Detailed explanation of usage method
Basic measurement steps
Choose measurement location: Select 3-4 different positions on the circumference of the tire (due to uneven tire wear)

Positioning measurement point:

Insert the scale vertically into the groove of the pattern

Ensure complete contact between the bottom and the bottom of the groove

Avoid wear indicator blocks (small rubber blocks that protrude from the tire itself)

Read values:

Observe the numerical value of the contact position between the scale and the tire surface

Record data for each measurement point

Calculate the average value as the current tread depth of the tire

Comparison standards:

New tire tread depth: usually 8-9mm (for passenger cars)

Statutory minimum depth: 1.6mm in most countries (recommended to consider replacement at 3mm)

High performance tires may need to be replaced earlier.
