How to check your car’s tread depth?

In the US, car owners use the quarter trick like a 25-cent coin to check how worn the tires are. Luckily, in the Philippines, we have P1 coin which has almost the same diameter as the 25-cent coin to use as an alternative.

So, how to use the P1 coin to check your car’s tread depth? Very easy. Put the coin into the groove and Jose Rizal's head on the coin is upright:

  • If the year lying below the head of Rizal is partly covered when put inside, your tires’ tread depth is still in a good condition.
  • On the other hand, if the groove can cover the whole of the coin, congratulations, your car is in need of a new tire! Replace it.

Remember that you have to do this step across the tire’s length. In the UK, if you check 75% of the length and the tire’s tread is at least 1.6mm, your car tire is still at a safe level. Here is a step-by-step instruction with video on how to change your car tires.
