Tyre condition test.
Tread depth and safety.
Inspect your tyre safety honestly at home. Measure tread depth with a 2-euro coin or a matchstick, verify rubber age and hardening, and get a clear recommendation.
Accurate tyre inspection requires no special tools. Check physical tread groove depth with a coin or matchstick, verify rubber age from the sidewall code, or consult a local tyre shop.
Measuring tread depth
Choose whether to measure using a pocket coin or a standard matchstick.
Locate the main longitudinal groove in the center of the tyre, not the outer shoulder.
Insert the coin vertically along the groove channel so its outer edge rests at the bottom.
Jos 2 € kolikon 4 mm hopeareunus peittyy kokonaan kumiin, talvipito on turvallinen.
Tread depth of 4.2 mm covers the test marker completely. Evacuation of water and slush remains safe.
