What size tires does the Haval F7 use?

The Haval F7 uses two different tire specifications: 225/55r19 and 225/65r17. Typically, higher-end models are equipped with larger wheels, which require correspondingly larger tires. Tires operate under complex and demanding conditions, enduring various deformations, loads, and extreme temperatures during driving. Therefore, they must possess high load-bearing capacity, traction performance, cushioning capability, and wear resistance. In terms of exterior design, the car's side profile presents a robust appearance, with multiple character lines enhancing the sense of layering. The chrome-trimmed window lines rise towards the rear and taper at the tail, adding visual tension.

Is ETC mandatory on highways now?

Highways can be accessed without ETC. Because ETC is not mandatory to install. Since January 1, 2020, vehicles without ETC will no longer enjoy various toll reduction policies, and can only pay tolls through manual lanes when passing toll stations. It may be a bit inconvenient during holidays. ETC is just a different toll collection method and has nothing to do with whether you can access highways. There are two toll collection methods on highways: manual toll collection and ETC toll collection. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopy of the owner's valid ID card and vehicle license. If it is not the owner who applies, you also need to bring the agent's valid ID card. The photocopy of the vehicle license needs to include the page with the most recent annual inspection stamp; a bank card for deducting highway tolls; aged between 18 and 60; and the vehicle must be under the individual's name. How ETC works: Through the on-board electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane of the toll station, and uses computer networking technology to settle accounts with the bank in the background, allowing the vehicle to pay highway or bridge tolls without stopping when passing through highway or bridge toll stations. Benefits of installing ETC: Save time: Avoid the hassle of queuing and waiting; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Save wear and tear: Save costs, reduce the frequency of vehicle starts and stops, reduce wear and fuel consumption, and users can enjoy toll discounts; Improve efficiency: The passing efficiency of ETC lanes can theoretically be increased by 2-3 times or more, making traditional ETC updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What are the signs of poor tire grip?

Tires with insufficient grip will make the car feel unstable while driving, and understeer may occur when cornering. For cars with poor grip, it is necessary to reduce speed when entering a corner to ensure that understeer does not occur. Drivers will feel that the car is difficult to control. Grip mainly depends on parameters such as tire tread pattern, tread depth, road surface conditions, and vehicle load. There are two ways to increase the friction between the tire and the ground. The first is to increase the friction coefficient of the road surface. The so-called "friction coefficient" refers to the road surface's ability to provide grip for the tire. The higher the friction coefficient, the greater the grip. Different road surfaces, such as asphalt, concrete, and gravel, have different friction coefficients and thus provide varying levels of grip for the tire. The second method is to increase the tire's own friction coefficient, which can be achieved by choosing softer tires. Softer tires provide stronger grip but wear out faster. To increase the tire's contact area with the road surface, the simplest method is to switch to wider tires. Another option is to use tires with fewer tread patterns, which can increase the actual contact area between the tire and the ground, but this may affect grip performance on wet or slippery surfaces. With a given contact area, the tire's potential can be fully realized through correct tire pressure and precise suspension tuning. The tire's contact area is always smaller when driving on a flat straight road compared to when stationary, and it decreases even further when driving on uneven roads or cornering due to vertical or lateral forces, sometimes even losing contact with the ground entirely. The ultimate goal of suspension improvement is to keep the tire in contact with the ground as much as possible, especially when cornering or driving on uneven surfaces.

How to Replace the Battery in a Geely Key?

Method for replacing the battery in a Geely key: 1. Press the button on the side of the vehicle key to remove the mechanical key; 2. Use a tool to pry open the buckle under the key casing to separate the outer shell; 3. Once the outer shell is pried open, the key casing can be accessed; 4. Remove the old battery and replace it with a new one, then snap the casing back into place to complete the process. Geely Holding Group owns brands such as Geely Auto, Lynk & Co, Volvo Cars, Polestar, and Proton. Taking the Geely Emgrand as an example, its body dimensions are 4631mm in length, 1789mm in width, and 1470mm in height, with a wheelbase of 2650mm. The shield-shaped contour of the Geely Emgrand features a 'V' design, symbolizing the brand's entry into the high-end automotive sector with a stance of luxury, stability, and strength.

Do You Need to Watch the Entire Car Maintenance Process?

At a regular 4S dealership, you don't need to watch the entire car maintenance process. 4S shops use standard techniques and genuine auto parts, so major issues are unlikely to occur during maintenance. The content and purpose of car maintenance are as follows: Car Maintenance Content: Modern car maintenance primarily includes servicing the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. Purpose of Car Maintenance: The purpose of car maintenance is to keep the vehicle clean and tidy, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down deterioration, and extend the service life.

What does 5w40 engine oil mean?

5w40 engine oil represents the following: w stands for winter, the preceding 5 indicates the lowest temperature at which the engine can start, and 40 represents the viscosity level, with higher numbers indicating higher viscosity. 5w40 engine oil is suitable for electronically fuel-injected gasoline engines equipped with crankcase ventilation devices and catalytic converters operating under various conditions. Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, and provide sealing to prevent leaks. It consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics, making them an essential part of the lubricant.
