Tire tread depth measure card

Tire tread height gauge  

Simple to use

A very practical tire tread depth gauge. All you need to do is put the tip of the device against the tread and measure it.
The element is equipped with an extension block. Scale - 1-20 mm (graduated every 1 mm)

How to measure the tread?

• Measure the height of the grooves in the center of the tread.
• Measure in line (in the same groove) at three places with fairly equal intervals. Make sure the tread wears evenly over the entire surface of the tire.
• Press the tip to the bottom of the groove and read the value on the indicator.
• Tread depth measurement is the perfect time to check the depth of the side grooves, if they wear unevenly, the cause may be incorrect wheel alignment.

Some important facts

The officially established minimum tread depth in Poland is 1.6mm. Driving on tires with a tread with a smaller tread height may result in a fine and with the registration certificate being kept.

For safety reasons, tire manufacturers recommend replacing the tires after exceeding the tread depth: 3mm for summer tires and 4mm for winter tires, respectively.

Driving on worn-out tires drastically reduces traction and increases the likelihood of aquaplaning (water cushion).
