Method for viewing car tire model numbers: The tire model number is printed on the sidewall of the tire. Upon close inspection, you can see markings such as P215/65R1589H: P indicates a passenger car tire; 215 refers to the tire's section width, which is the distance between the two sidewalls (measured in millimeters); 65 is the tire's aspect ratio, representing the ratio of height to width; R denotes the tire's structure, indicating it is a radial tire; 15 signifies the rim diameter in inches. Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car's suspension system, they help absorb shocks encountered during driving, ensuring good ride comfort and smooth driving performance.

How to turn off the continuously flashing left and right turn signals?

Under the steering wheel, there is a turn signal switch. Pushing it downward activates the left turn signal, while pushing it upward activates the right turn signal. Setting it to the middle position turns it off. On the left side of the steering wheel, there is a light control lever. Pushing it upward turns on the left turn signal, while pushing it downward activates the right turn signal.
