How to Check Tread depth on tires? - Because it is the only part that grips the road, the tire tread depth is a very important part of your security. There is also a store of value for the tire condition. If you run too low tread depth increases the risk of tire damage, aquaplaning and performance degradation. A low tread depth on car can be, especially in winter, greatly reducing grip and control.
The tires have a tread depth of at least 1.6 mm and 3.0 mm tires.
Step 1 - Before you check the tread depth on tires
The first step is to get good overview of the front tires
Park on a flat and level surface
Use the handbrake and put the car in park position (for automatic cars) or first gear (for manual transmission cars).
Turn the steering wheel 45 degrees to the right or left, so you have a clear view of the deck you want to inspect.
It is obviously difficult for the rear tires, but hopefully you can still get a fairly good view of the pattern that you should inspect.
Step 2 - Check the tread depth on Tires
Now that the front tires are easily accessible, you can start controlling the pattern and tire condition. Guess you do not arrive! Check tread depth at regular intervals with a tread depth gauge. It makes it much easier to measure and furthermore, it is fast.
Summer must have at least 1.6mm tread depth (3.0 mm for winter tires) in the main pattern (corresponding to the central 75% of the tread width) around the entire circumference of the tire. Always
check the tread depth on tires at several places. All tires also have tread warner and when they are level with the tread, the tire has reached the legal limit. It is then high time to replace them.
