2 Answers
245/45R18 is the tire specification for the Mercedes-Benz E300. The first number, 245, represents the tire width of 245MM. The number 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width. The number 18 represents the rim diameter of 18 inches. The middle letter or symbol has a special meaning: "R" stands for radial tire. The tire brand for the Mercedes-Benz E300 is Bridgestone, featuring a five-spoke hollow design. If you want to replace the tires yourself, you can follow the steps below: 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, and you should check to ensure the jack is at a right angle to the ground; Remove the hubcap and loosen the nuts counterclockwise. Do not fully loosen the nuts; just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts, not the tire, are turning; 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 wheel hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are concealed. At this point, the tire replacement is complete. Besides the model, tires also display the following common data: Tire carcass ply material: Indicated by Chinese pinyin, such as M for cotton ply, R for rayon ply, N for nylon ply, G for steel ply, and ZG for steel radial ply tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters from A to Z represent certified speed ratings ranging 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.
I have extensive experience in car repairs. The tire model for the Mercedes-Benz E300 depends on the specific year and configuration. The standard version usually uses 245/45R18 or 225/55R17, meaning the tire width is 245mm, the aspect ratio is 45%, and the wheel size is 18 inches. This design is suitable for comfort and fuel efficiency. I recommend you first check the markings on the side of the tire, where the detailed size is indicated, or look at the information sticker near the driver's side door. Don't casually switch to non-original specifications—larger wheels affect fuel consumption, and narrower tires reduce handling. Safety comes first. If the tires are severely worn, replace them promptly at an authorized dealership to match the original factory recommendations and avoid misalignment. Remember, regular tire pressure checks can extend their lifespan—inspecting them once a month is a good practice.
