What are the tire specifications for the Audi Q7?

[DeKevin]

The Audi Q7 has two tire specifications. The 45TFSI quattro S line Luxury model is equipped with 285/45R20 tires, and the 55TFSI quattro S line Sport model is equipped with 285/40R21 tires. In the 285/45R20 specification, the first number 285 represents the tire width of 285MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, and 20 represents the rim diameter of 20 inches. The letter "R" in the middle stands for radial tire. In the 285/40R21 specification, the first number 285 represents the tire width of 285MM, 40 indicates the aspect ratio of the tire section is 40%, meaning the section height is 40% of the width, and 21 represents the rim diameter of 21 inches. The letter "R" in the middle stands for radial tire. The Audi Q7 uses Dunlop tires and offers two rim styles. The 20-inch rims feature a sporty vortex design, while the 21-inch rims have a dual five-spoke design. None of the models come with a spare tire as standard. If you want to change the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring it touches the metal part of the frame. Raise the jack until it supports the car. The jack should be positioned under the vehicle, and you should check to ensure it is at a right angle to the ground. Remove the hub cover and loosen the nuts counterclockwise. Do not fully loosen the nuts; just loosen them enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn instead of the tire. Turn the nuts counterclockwise until they come off. Repeat this step for all lug nuts and then remove them completely. Place the new tire on the rim, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are snug. At this point, the tire replacement is complete. In addition to the specifications, 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, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry its rated load under specified conditions. Letters from 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 size compatible with the tire for practical use, such as standard rim 5.00F.
