How Thick Are Car Tires?

Car tires generally have a thickness of around 13-15mm. Below is a detailed introduction to tire thickness: Tread and Sidewall Thickness: The tread consists of the tread pattern and the crown. For ordinary family car tires, the thickness of the front crown is about 13mm (with the tread pattern being around 7mm thick and the crown about 6mm), while the sidewall is thinner, with a thickness of approximately 5mm. For off-road vehicle tires, the front crown thickness is about 20mm (with the tread pattern around 14mm thick and the crown about 6mm), and the sidewall thickness is around 10mm. Tire Replacement Based on Wear: It is important to regularly monitor the wear of the tread pattern and check its thickness. If the wear is severe and the thickness falls below 1.6mm, the tire should be replaced, as it may otherwise affect the tire's grip and the vehicle's handling performance.
I've been driving for over a decade, and the topic of tire thickness brings back many daily driving experiences. Generally speaking, the thickness of car tires is mainly concentrated in the tread part, which is the part that contacts the road surface, measuring about 6 to 10 millimeters when new. However, as the vehicle is used over time, it gradually wears thin, especially for cars that frequently drive on highways, where the wear is more rapid. Every time I service my car, I check the tread depth using that small tool; if it's less than 1.6 millimeters, I feel it's time to replace them, otherwise, braking in rainy conditions can easily lead to skidding, increasing the risk. The sidewall thickness is also crucial, typically around 3 to 5 millimeters, affecting overall stability—if it's too thin and you hit a curb, it might cause a blowout. Overall, thickness directly impacts safety and comfort, so I recommend checking the condition of your tires every six months.
Safe driving is my top priority, and tire thickness isn't just a number—it's about protection. For instance, the sidewalls of new tires are typically 3-6 mm thick, providing cushioning against road impacts, while the tread depth ranges from 6-12 mm, determining durability and grip. On long trips, I'm extra cautious, as overly worn thin tires are more prone to punctures from sharp objects, which can lead to accidents. I recall a tire blowout once due to neglected checks; since then, I've made it a habit to monitor thickness changes using mobile apps or visual gauges. Additionally, different vehicle types have varying needs—compact cars usually have thinner tires, while larger vehicles require thicker ones. In short, maintaining proper thickness is key to risk prevention, and regular maintenance saves hassle in the long run.
