Tire tread depth and its importance

Tire tread depth

Have you ever considered why your tires have various patterns, designs, knobs, curves, and grooves? The tires could have been plain with no decorations, but you'd never seen anything like that before. There is always a reason for things to exist, and tire tread patterns are no exception. They have a significance and are more important than you would think. Before we explain why it matters, let's define a tire tread depth in its purest form.

Definition of tire depth?

What is the definition of tire depth?

There are two points outside of a tire if you notice, one is the top of the pattern and the other one is the deepest groove. The distance between the two makes the tire tread depth. It is the vertical distance between the two. The tread depth is important in order to keep the tire safe and long lasting. 

In general, the center of a tire has the most tread depth, while the edge has the least. The tread depth of the tire might be the same throughout the tread based on the use and technical specifications of the tire.

Tread depth on new tires ranges from 8 to 9 millimeters, or 10/32 to 11/32 inch in inches. Because of uneven roads, high speeds, or frequent driving, the tread wears down over time. If the tread depth goes below 1.6 millimeters, the tire might perform less. Breaking performance can be affected with lower tread depths in winter. This might result in poor vehicle handling. Continental  tires suggest the minimum tread depth of 1.6 millimeters.

The basic purpose of a tire is to connect the vehicle to the road. At high speeds, the tread is constantly on the road. The patterns on the tire help to provide traction, which helps to create a smooth braking. Stopping a vehicle appears to be a slippery slope if they are not present. Furthermore, braking becomes difficult in wet conditions, and water on the road has no area to move through the tires. This is why it's critical to check your tires' tread depth.

Tires lose tread depth while running on the road. This eventually results in low tire performance. Unfortunately, there is no way of saving the tires from losing the tire depth as it is the nature of the rubber when it goes on a road. 

 

Even tread wear is common across the tire, uneven tread wear might indicate poor inflation, wheel misalignment, or a range of other issues. Get your car checked out by a professional if you see uneven tread wear.
