How to Read Car Tire Specifications?

[DelKinsley]

Car tire specifications, such as 225/65R17, can be interpreted as follows: 225 represents the tire width in millimeters (225 mm), 65 indicates the aspect ratio (65), R stands for radial tire, and 17 denotes the rim diameter in inches (17 inches). The manufacturing year of the tire is usually found on the sidewall in a format like DOTXXXXX1113, where the last four digits after DOT represent the production date. The last two digits indicate the year of production, while the first two digits signify the production week. Car tires are one of the essential components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to absorb shocks during driving. They ensure a comfortable ride and smooth driving experience, maintain good traction between the wheels and the road, enhance the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car.
