What is the tire size of the XC60?
2 Answers
The XC60 comes with two tire sizes: 235/60R18 and 235/55R19. In 235/60R18, the first number 235 represents the tire width of 235MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, 18 stands for the rim diameter of 18 inches, and the middle letter "R" denotes a radial tire. In 235/55R19, the first number 235 represents the tire width of 235MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, 19 stands for the rim diameter of 19 inches, and the middle letter "R" denotes a radial tire. The XC60's tires feature a dual five-spoke radial wheel design. The rims equipped on this model bear the "XC" insignia. If you wish to replace the tires yourself, follow these steps: Retrieve the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack contacts the metal part of the frame; Raise the jack until it supports the car, making sure the jack is positioned under the vehicle and forms a right angle with the ground; Remove the hubcap, loosen the nuts counterclockwise without fully removing them, just enough to eliminate resistance. Keeping the tire on the ground while loosening the nuts ensures the nuts turn, not the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, then fully 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 hand-tighten them until all nuts are concealed. The tire replacement is now complete. Besides the model, tires also display the following common data: 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 tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined 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: Shows the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".
Speaking of the XC60's tire size, my 2019 model came standard with 235/60 R18, which I'm still using. The 235 refers to the tire width of 235 millimeters, the 60 is the aspect ratio indicating the height is 60% of the width, and R18 means 18-inch wheels. It feels very stable on the highway with minimal bumps, offering good comfort and low noise, making it ideal for daily family use. The sport version or newer models might come with 235/55 R19 for a sportier feel, though slightly bumpier. When replacing tires, always check the label on the door frame or the manual for specifications—don't randomly change sizes, as it can affect speedometer accuracy and fuel consumption, and in severe cases, the ABS might malfunction. Last time I replaced tires at the dealership, they emphasized using the original size to ensure safe driving.
