Beyond the annual revisions from the age of 5, the tires cannot always be rushed until they meet a decade. There are a number of previous tracks that tell you when it is essential to change the wheels to a car.
First of all, you must change the wheels to a car yes or Yes when the tread has worn down below the indicated depth mark on a tyre.
You should also do so when the flank (lateral side adjacent to tread) is damaged.
Another reason why it is essential to change the wheels to a car is the appearance of a hole of more than 6 millimeters in diameter in the tread.
Lastly, if the heel (flange that sits on the wheel) is damaged or warped, you must also change the tires.
