What is the tire model of the Peugeot 4008?

The tire specifications and sizes for the Peugeot 4008 are as follows: Peugeot 4008-2022 model 400THP Chuangxiang Edition-225/55R18, Peugeot 4008-2021 model 360THP Fengrui Edition-215/65R17; Peugeot 4008-2021 model 400THP Zhizhen GT Edition-235/50R19. The first numbers 215, 235, and 225 represent the tire width in millimeters (215MM, 235MM, 225MM). The numbers 65, 55, and 50 indicate the aspect ratio of the tire's cross-section (65%, 55%, 50%), meaning the height of the cross-section is 65%, 55%, and 50% of the width, respectively. The numbers 18, 17, and 19 represent the rim diameter in inches (18, 17, 19 inches). The letter "R" in the middle stands for radial tire. The Peugeot 4008 is equipped with Michelin e.Primacy tires, and the spare tire is a non-full-size one. Tire maintenance methods: Regularly check tire pressure. Tire pressure is a crucial factor affecting tire lifespan; it should not be too high or too low. Always inflate according to the vehicle's indicated tire pressure. In summer, try to keep the tire pressure slightly lower; in winter, ensure the tire pressure is slightly higher than in summer due to thermal expansion and contraction. This ensures a comfortable and safe driving experience. Frequently inspect tire wear. Some vehicles may experience uneven tire wear ("tire cupping"), so it's essential to check the tires regularly, especially the inner side, for abnormal wear. Pay attention to whether the tread depth is consistent on both sides. Promptly remove small stones and other debris from the tires. Foreign objects in the tire treads can pose potential hazards, as they may fly out while driving. Therefore, keep the tires as clean as possible. Besides the model, tires also display the following common data: Tire cord material: Represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord. 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 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: Shows the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".

How Long Does Wheel Rim Repair Take?

Aluminum alloy wheel rim scratch repair typically takes about 1 day. Whether a scratched wheel rim can be repaired depends on the following factors: 1. Rim material: Chrome-plated or polished rims cannot be repaired because their surfaces are too glossy to restore. 2. Severity of scratches: If the scratches haven't exposed the primer, they only affect appearance without causing other damage, and may not require repair. 3. Exposed primer: If the scratches have exposed the primer, repair is necessary. Unrepaired primer exposure may lead to wrinkling and expansion of the damaged area over time, along with rust and corrosion.

Why is the idle speed high in winter?

In winter, the high idle speed occurs because the engine's normal operating water temperature is around 90 degrees Celsius. In extremely low temperatures, after the engine starts, the water temperature sensor sends a signal to the ECU, prompting the engine to increase fuel injection and air intake, thereby raising the engine speed to quickly reach the normal operating temperature. As the engine temperature gradually rises, the idle speed will also gradually decrease to normal levels. The increase in idle speed after a cold start is a normal phenomenon, serving as a protective measure for the engine by the car, and also aimed at improving combustion efficiency and meeting emission standards. The car engine is the device that provides power to the vehicle, acting as the heart of the car, and determines the vehicle's power, fuel economy, stability, and environmental friendliness.
