[Richard]

The tire models for the Civic are 215/50R17 and 215/55R16. In 215/50R17, the first number 215 represents the tire width of 215MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 17 represents the rim diameter of 17 inches. The middle letter "R" stands for radial tire. In 215/55R16, the first number 215 represents the tire width of 215MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 16 represents the rim diameter of 16 inches. The middle letter "R" stands for radial tire. The original factory tires for the Civic are Yokohama tires. Yokohama Tire was founded in 1917, with the English name Yokohama, and is also known as Yokohama Tire in China. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car. The jack should be positioned under the vehicle. Check and ensure the jack is at a right angle to the ground; Remove the hub cover, loosen the nuts counterclockwise. Do not completely loosen the nuts; just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn, not the tire. Turn the nuts counterclockwise until they come off. Repeat this step for all lug nuts and completely remove the nuts; Place the new tire on the wheel hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are concealed. At this point, the tire replacement is complete. In addition to the model, tires also have the following common markings: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim specification compatible with the tire for practical use, such as standard rim 5.00F.
