What is the thickness of a tire?
2 Answers
Tire thickness varies depending on the position: 1. The tread thickness is approximately 13mm; 2. The sidewall thickness is around 5mm. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are categorized by their usage: 1. Passenger tires; 2. Summer tires; 3. Summer high-performance tires; 4. Winter tires; 5. Heavy-duty and light truck tires. The maintenance methods for tires include: 1. Regularly check tire pressure and inflate according to the vehicle's indicated pressure; 2. Frequently remove debris from tire treads to avoid blowouts; 3. Inspect tire wear and replace them promptly based on wear conditions; 4. Perform four-wheel rotation to ensure even force distribution and prevent excessive wear; 5. Avoid curbs and potholes.
Tire thickness actually refers more to tread depth, not the overall thickness of the tire. I just got new tires, and the factory tread depth is usually between 8/32 and 11/32 inches, which is about 6 to 8 millimeters. But they gradually wear down with use—for example, driving too much in the rain can accelerate wear, so regular checks are necessary. I often use a simple method: insert a coin into the tread groove. If Lincoln's head is fully visible, it means the depth is less than 3/32 inches, and it's time to replace the tires. This thickness directly affects grip and safety—too thin, and braking distance increases, making it easier to skid on wet roads. I've seen a friend's car lose control due to thin tires. New tires from the factory are marked with a minimum legal limit of 1.6 millimeters, but I suggest replacing them before they get that thin to avoid risks. Different tire brands vary significantly—all-season tires might start thicker, while snow tires are even thicker, but their wear patterns are similar. Anyway, checking every 10,000 kilometers is best—don't delay too long to save money, safety comes first!
