1. Tread depth - visual inspection
Branded tires have indicator strips (IN), which become noticeable when the tread depth is reduced to 1.6 mm. The position of the indicators is indicated by triangular marks on the side of the treadmill (A).
2. Tread Depth - Manual Check
Alternatively, the tread depth can be measured with a simple device known as a tread depth indicator.
3. Check tire pressure
Check tire pressure regularly. Tires must be cold when checking, do not check pressure immediately after a long drive, otherwise you will get an incorrect result.
