How Thick Is the Front of a Tire?

Generally, the tread thickness of a car tire is about 13mm. Here is some information about tires: 1. Introduction: The sidewall thickness of a tire is 5mm. Car tires can be divided into pneumatic tires and solid tires based on their carcass structure. Most modern cars use pneumatic tires. Depending on the internal air pressure, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. 2. Types: Low-pressure tires are commonly used in various vehicles. Pneumatic tires can also be divided into tube tires and tubeless tires based on their structure. Tubeless tires are widely used in passenger cars. Depending on the arrangement of the internal cord ply and buffer layer, tires can be further classified into radial tires and bias tires. Radial tires are commonly used in vehicles. The sidewalls of tires are usually marked with relevant information.
The front side of a tire is also called the tread, and its thickness is usually around 8 to 10 millimeters when new, but this is not fixed as it wears down significantly with driving. Having driven for several years, my biggest concern is the thinning of this thickness affecting safety, especially on highways where reduced tire grip leads to longer braking distances and increased risk of slipping in rainy conditions. The key is to monitor the tread depth—new tires have about 8-9 mm of depth, and when it wears down below 1.6 mm, it becomes dangerous, requiring immediate replacement. I regularly check it using a one-yuan coin or a specialized caliper, and during each maintenance session, I ask the technician to take a quick look. Additionally, excessively thin treads can lead to blowouts, especially in old tires or those used frequently for high-speed driving. Never compromise safety to save money—safety comes first. In summary, paying attention to wear is far more important than simply asking about thickness, and developing this habit can help avoid major troubles.
