The 2020 Volkswagen Teramont comes with three tire size specifications: 255/50R20, 255/55R19, and 245/60R18. In 255/50R20, the first number 255 represents the tire width of 255MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 20 stands for the rim diameter of 20 inches. The letter "R" in the middle denotes a radial tire. In 255/55R19, the first number 255 represents the tire width of 255MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 19 stands for the rim diameter of 19 inches. The letter "R" in the middle denotes a radial tire. In 245/60R18, the first number 245 represents the tire width of 245MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, and 18 stands for the rim diameter of 18 inches. The letter "R" in the middle denotes a radial tire. The 2020 Volkswagen Teramont tires are from the Continental brand, featuring a polished double five-spoke wheel design, with a non-full-size spare tire. If you want to replace the tires yourself, follow these steps: Take out 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 at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise, but do not fully unscrew them—just enough to eliminate resistance. Keeping the tire on the ground when loosening the nuts ensures the nuts turn, not the tire; Turn the nuts counterclockwise until they come off, repeating this step for all lug nuts, then remove them completely; Place the new tire on the hub, carefully aligning the tire rim with the wheel bolts, install the lug nuts, and tighten them by hand until all nuts are snug. 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, and ZG for steel radial cord tires. 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 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h; Rim specification: Indicates the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".
