The same question is repeated every time I change tires. ARE MY TIRES STILL GOOD? You always trust your mechanic, but this year you would like to make sure yourself. Here is some advice to evaluate the wear of your tires.

Standards to be respected

In Quebec, the SAAQ asks to change any tire whose tread reaches a thickness less than 1.6 mm (2/32 of an inch). This measure is the point of no return after passing this mark, it becomes dangerous to use your tires since their grip is greatly affected. On the other hand, the SAAQ indicates that a tire begins to lose its grip when the thickness of the tread is less than 4.6mm (6/32 of an inch). This does not mean that your tires are no longer good from this measurement, but rather that the deterioration starts from this point.

How to measure tread wear


The simplest method of calculating wear is by using one of these small tools.

This small gauge is very easy to use. Simply push the black tabs on the tread and slide the metal rod deeper into the tire. When all this is done, you can read on the top part the measurement in millimeters or inches. This measurement tool is available in almost all parts retailers in Quebec, or online.

There are other methods, however, to calculate the wear on your tires. For example, your tires are equipped with a wear indicator that is located in the tread of your tire. Here is an example:


If the tread is made flat with the indicator, this means that your tire is returned to wear of 1.6 mm (2/32 inch) and that it is now time to change them.

If you have no tools at home, you can still use the famous 25 cents test. Just insert the piece into the scratch, the front of the caribou first towards the bottom of the tire. If you see the muzzle of the caribou, it means that your tire is less than 6/32 inch (4.6mm) thick and you have to start looking for new tires for the next season.


Some little tips

It is important to always take the wear of your 4 tires. Uneven wear can be a sign of misalignment or parts to replace. To get more tips on how to choose new tires for your car please check out the best tires for subaru outback here.

The rotation of the tires allows a more uniform wear. Braking mainly wears the front wheels while traction or propulsion wears the wheel which transmits the rolling on the road.

Make sure you always have adequate pressure in your tires. Adequate pressure equals adequate bearing, which gives you minimal and even wear on your tires. In addition, good pressure could save you fuel in the long run.
