The tire model specification for the Mercedes-Benz E300 is 245/45R18. The first number, 245, represents the tire width of 245MM. The number 45 indicates the aspect ratio of the tire's cross-section is 45%, meaning the height of the cross-section is 45% of the width. The number 18 represents the rim diameter of 18 inches, and the letter "R" in the middle stands for radial tire. The Mercedes-Benz E300 uses Bridgestone TURANZA run-flat tires, with five-spoke hollow-designed rims. None of the models come with a spare tire as standard. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and the jack, place the jack under the frame of the tire you want to replace, 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 completely remove 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, not the tire, are turning. Continue turning the nuts counterclockwise until they are loose. 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 concealed. At this point, the tire replacement is complete. In addition to the model, the tire also carries 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 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 specification compatible with the tire for practical use, such as standard rim 5.00F.

What are the functions of coolant?

Coolant functions: 1. Circulate in the engine cooling system to carry away excess heat generated during engine operation, enabling the engine to operate at normal working temperature; 2. Has a higher boiling point and lower freezing point than water, providing antifreeze protection; 3. Corrosion prevention, as coolants contain a certain amount of anti-corrosion additives to prevent corrosion in the cooling system; 4. Prevents the formation of deposits such as scale. The full name of coolant should be antifreeze coolant, meaning it has antifreeze functionality. Coolant consists of three components: water, antifreeze, and additives.
