What is the tire size of the CS75?
2 Answers
The CS75 has three tire sizes: 225/55R19, 225/60R18, and 225/65R17. In 225/55R19, the first number 225 represents the tire width of 225MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 19 represents the rim diameter of 19 inches. The middle letter "R" stands for radial tire. In 225/60R18, the first number 225 represents the tire width of 225MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, and 18 represents the rim diameter of 18 inches. The middle letter "R" stands for radial tire. In 225/65R17, the first number 225 represents the tire width of 225MM, 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width, and 17 represents the rim diameter of 17 inches. The middle letter "R" stands for radial tire. The CS75 uses Yokohama brand tires. The spare tire is non-full size. If you want to replace the tire yourself, follow these steps: 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 perpendicular to the ground; Remove the hubcap, loosen the nuts counterclockwise, do not completely loosen them, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures the nuts turn rather than 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 hub, carefully align the tire rim with the wheel bolts, install the lug nuts, tighten the nuts by hand until all nuts are concealed, at this point the tire replacement is complete. In addition to the model, the tire also has the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters A to Z represent the 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".
I've been driving the CS75 since 2018, and the tires I use are the standard 225/65 R17. The 225 represents the tire width of 225 millimeters, 65 is the aspect ratio, meaning the height is 65% of the width, and R17 refers to the 17-inch wheel hub. This size is quite comfortable for daily driving, especially on city roads with minimal bumpiness, and provides stable grip at high speeds. However, maintenance is crucial: I check the tire pressure monthly, keeping it around 2.3 bar. If it's low, I add air; if it's high, I release some to avoid the risk of a blowout. Remember to slow down when driving in the rain, as this size handles water drainage reasonably well. If you switch to a different size, like 235-width tires, the car may look more stylish, but fuel consumption could increase by a point or two. Tire lifespan is generally around 50,000 kilometers. I've used Pirelli tires, which are durable and quiet. Don’t forget to perform wheel balancing when changing tires, otherwise the car may vibrate while driving.
