What Are the Basic Knowledge Points About Tires?

Tire basics are as follows: Tire Size: The tire size is printed on the sidewall and is represented in two ways: High-pressure tires are generally denoted by "tire diameter × tire section width," such as 34×7; low-pressure tires are usually represented by "section width ~ rim diameter," such as 7.5~20, with the unit in inches (1in=0.0254m). Replacement Standard: According to technical standards, tires should be replaced when the tread grooves are less than 1.6mm. If the wear indicators on the tread grooves are exposed, it indicates that the groove depth is insufficient at 1.6mm. The tire wear indicators are the raised sections within the tread grooves. Using tires with remaining tread depth below 1.6mm may result in sudden loss of traction and braking force in rainy conditions, as well as a complete lack of traction in snowy conditions.
Basic knowledge of tires. As an enthusiast in vehicle maintenance, I believe it's essential to start with the structure: tires are divided into the tread, sidewall, and inner liner. The tread is responsible for traction, and deeper tread patterns provide better safety in rain or snow. Different types of tires, such as summer tires, winter tires, and all-season tires, can affect performance if chosen incorrectly. Tire pressure is crucial—too high accelerates wear, while too low increases fuel consumption and raises the risk of a blowout. I always use a tire pressure gauge to check monthly. To check tread depth, insert a coin; if you can see Lincoln's head, it's time to replace the tire—generally, less than 1.6mm is dangerous. Finally, maintenance: rotate tires regularly to balance wear and extend their lifespan. Never wait until a blowout to make repairs.
After driving for so many years, I've realized that tires are the foundation of foundations: the size is marked on the side, like 185/65 R15, where the first two numbers indicate the width and aspect ratio. Maintaining proper tire pressure is crucial, usually with recommended values on the door frame, and I check it every time I refuel. Worn treads can easily cause skidding, especially on wet roads, so I manually check the depth every season. Using winter or snow tires in cold weather is essential—don't skimp on that. When replacing tires, I prioritize durable brands over the most expensive ones. Simple maintenance, like avoiding sudden braking, can save on repair costs.
For beginner drivers, here's a brief introduction to tire basics: In size markings like 185/65 R15, the "R" stands for radial construction. Tire pressure affects stability and fuel consumption, so check it regularly. Tread provides traction; replace tires when it's worn. I use a mobile app to track tire replacement cycles—typically every 4-5 years or after driving 60,000-80,000 kilometers. Choose tires based on climate; summer tires are sufficient in the south. Perform a quick weekly check for bulges on the sidewalls to avoid surprises.
