What is the explanation of tire specification parameters?

The explanation of tire specification parameters is: The international standard tire code, expressed in millimeters for the section width and the percentage of the aspect ratio, followed by the tire type code, rim diameter (in inches), load index (allowable load mass code), and allowable vehicle speed code. Taking 215/70R15 as an example: The meanings of 215/70R15 are respectively: 215 represents the tire section width, the unit is mm, with an interval of 10mm; 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, 70 represents 70%, generally the aspect ratio of tires ranges from 30% to 80%. Under normal circumstances, ordinary cars should not use tires with an aspect ratio greater than 75%, while luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio less than 60%; R is the abbreviation of Radial, indicating that the tire has a radial structure, and 15 is the outer diameter of the rim, the unit is inches.

How Often Should Transmission Fluid Be Changed?

Automatic transmission fluid generally needs to be changed every 2 years or approximately 40,000 to 60,000 kilometers; manual transmission fluid typically requires replacement around every 60,000 kilometers. Car owners can determine whether to change the transmission fluid based on the operating condition of the vehicle's transmission. If the vehicle experiences rough gear shifting, especially when the transmission noise becomes noticeably louder at speeds exceeding 100 kilometers per hour, it may be time to consider changing the transmission fluid. Transmission fluid is an essential lubricant that keeps the gear system clean, ensuring proper transmission operation and extending the lifespan of the drivetrain. It also performs functions such as cleaning, lubrication, rust prevention, and heat dissipation. Depending on the transmission type, transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid.

What is the maximum wading depth of the BMW 320?

According to official information, the maximum wading depth of the BMW 320 is 250mm. Common tire specifications are 225/45R18, with a body length of 4829mm or 4719mm, and it is a 4-door, 5-seat sedan. The maximum wading depth refers to the deepest water level a car can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs have a higher wading depth, but it is still best not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 has a maximum wading depth of 32 cm, the Volkswagen Sagitar has a maximum wading depth of 30 cm, the Land Rover Range Rover has a maximum wading depth of 90 cm, the Jeep Compass has a maximum wading depth of 48 cm, and the Highlander has a maximum wading depth of 45 cm. The maximum wading depth of SUVs is significantly higher than that of sedans. Generally, when driving through water, vehicle owners should take different measures depending on the depth of the water and the characteristics of the car itself, as detailed below: If the water depth reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the water depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom of the car, which could lead to short circuits and damage critical electrical components, preventing the car from starting normally. If the water depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions could cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.

What happens when a car pressure switch fails?

The symptoms of a failed car air conditioning pressure switch are: poor contact of the contacts or abnormal operation of the pressure switch, resulting in the compressor not working and failing to provide normal pressure protection. The car air conditioning pressure switch is an essential control component to ensure the normal operation of the car air conditioning refrigeration system. According to pressure control, it can be divided into high, medium, and low pressure; the wiring can be 2, 3, or 4 wires. The high and low pressure switches control the start and stop of the compressor when abnormal pressure occurs in the system. The following is an introduction to the content: 1. The control range of the high pressure switch is generally between 15-26 bar; 2. The low pressure switch is generally between 0-4 bar; 3. The medium pressure switch is generally 17 bar.

What is the brake pedal for?

As the name suggests, the brake pedal is the pedal that limits power, that is, the pedal of the foot brake (service brake). The brake pedal is used to slow down and stop the vehicle. It is one of the five major operating components of car driving and is used very frequently. How the driver controls it directly affects the safety of car driving. Extended information about the brake pedal is as follows: 1. During emergency braking, hold the steering wheel with both hands and do not operate it with one hand. 2. The size of the free travel of the brake pedal directly affects the braking time and braking distance. Therefore, before driving, be sure to check whether the free travel of the brake pedal is appropriate. 3. The braking action should be agile. If the vehicle skids, you can release the brake pedal, but the action of turning the steering wheel must be quick.

What are the new regulations for vehicle annual inspection within 10 years in 2020?

The exemption scope has been expanded from vehicles with 6 seats or fewer to non-operational small and mini passenger vehicles with 7-9 seats. Below is relevant information about the annual inspection: 1. Conditions: Vehicles whose condition does not match the records in the driving license or vehicle file, or whose license plates or driving licenses are damaged, incomplete, illegible, or self-made. 2. Notes: The vehicle's exterior cannot be modified. The color of the glass sunshade or explosion-proof film cannot be too dark (items inside the vehicle must be clearly visible from one meter away; mainly applies to vans and trucks, but not to passenger cars with 5 seats or fewer). Vans and trucks must have enlarged rear license plates, and the number of spring leaf plates cannot be increased or decreased. The number of seats in vans cannot be altered, and a fire extinguisher must be present. The cargo compartment of box trucks cannot be modified (no side doors, no roof openings, no tailgates). The size of the tires cannot be changed, and the tread patterns of tires on the same axle must be consistent. Vehicles with unresolved traffic violations or those impounded by the court cannot undergo the annual inspection.
