The Teramont has three tire size specifications: 265/45R21, 255/50R20, and 255/55R19. In 265/45R21, the first number 265 represents the tire width of 265MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, 21 represents the rim diameter of 21 inches, and the middle letter "R" stands for radial tire. 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, 20 represents the rim diameter of 20 inches, and the middle letter "R" stands for 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, 19 represents the rim diameter of 19 inches, and the middle letter "R" stands for radial tire. If you want to replace 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 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 hubcap, loosen the nuts counterclockwise, do not fully loosen them, just enough to eliminate resistance, keeping the tire on the ground when first loosening the nuts ensures the nuts turn rather than the tire; Turn the nuts counterclockwise until they come off, repeat this step for all lug nuts, completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, hand-tighten the nuts 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 marked on it: 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 the tire can carry the specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires 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 for several years. The Volkswagen Teramont SUV typically comes with tire size 255/55 R19, which means the tire width is 255mm, the height is 55% of the width, and the wheel diameter is 19 inches. Different configurations may have size adjustments, such as 18-inch for the base model and 20-inch for the high-end version. It feels stable and comfortable for daily driving. When replacing tires, remember to go to a professional shop or check the user manual to confirm the original specifications. Don't casually upgrade to larger wheels, as it can increase fuel consumption and affect handling. Tire maintenance is also important. I check the tire pressure monthly to keep it around 2.4 bar, reducing wear and extending lifespan. Before driving on highways, it's best to check the tread wear to ensure safety and prevent blowouts. After using them for several years, I recommend Michelin tires for comfort.

As a car enthusiast, the common tire size for the Touareg is 255/55 R19, with a width of 255 millimeters, an aspect ratio of 55%, and 19-inch rims. Having used them for a while, the size affects handling: wider tires offer better grip but slightly higher fuel consumption, while the 55% aspect ratio provides a softer ride. Larger rims look more stylish, but 18-inch ones are more economical and practical. When changing tires, always check the balance to prevent vibrations, and it's recommended to visit a 4S shop to ensure the speed rating matches the factory specifications. Regularly monitor tread depth and replace tires promptly if it falls below 2 millimeters. I've tried winter snow tires of the same size for added safety. If the budget allows, opt for low-noise brands like Goodyear for a quieter and less tiring experience on highways. Maintenance is simple—rotate the tires every six months to extend their lifespan.

I prioritize comfort when driving my Touareg, and the tire size is mostly 255/55 R19. The wide and flat profile enhances driving stability and reduces bumps. Choosing the right size also minimizes noise, making long drives less annoying. Once, I tried 20-inch tires which were a bit stiffer but handled corners more sharply. The original design with this ratio is quite reasonable, so I recommend not making random modifications to avoid affecting the suspension. Regularly checking tire pressure is a must—2.5 bar suits most road conditions, saving fuel and ensuring durability. If the tires are severely worn, replace them early; safety comes first.
