What is the wheel model of the Changan CS75?

The Changan CS75 has three tire specifications: 225/65R17, 225/60R18, and 225/55R19. Tires are usually mounted on metal rims to support the vehicle body, absorb external shocks, ensure contact with the road, and maintain driving performance. Here are some precautions for tire usage: 1. Regularly inspect tires: Increase awareness of tire safety by frequently checking them, especially before highway driving. Conduct thorough inspections, including tire pressure and checking for sidewall cracks or tread wear. Address any potential hazards promptly. 2. Regularly balance wheels: Excessive wheel imbalance can cause high-frequency vibrations at high speeds, leading to uneven tire wear and compromising driving safety. After tire repairs, perform dynamic balance testing and adjustments. The single-side dynamic balance test value should be ≤40 grams. 3. Rotate tires periodically: To ensure even wear across all tires on a vehicle, rotate tires every 5,000 km and perform a four-wheel alignment every 5,000–10,000 km to prevent abnormal or excessive wear. Do not install tires of different models or with significant wear differences on the same axle.

Must Motorcycles Ride in the Far Right Lane?

Motorcycles are not required to ride in the far right lane. According to Article 44 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," motorcycles should ride in the far right lane for safety reasons. Motorcycles: Motorcycles are two- or three-wheeled vehicles powered by gasoline engines and steered by handlebars. They are lightweight, flexible, and fast, widely used for patrols, passenger and cargo transport, and as sports equipment. Broadly, motorcycles can be categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. Power Knowledge: Horsepower was originally defined by the French and Germans. However, since the horses used to measure horsepower were smaller than average, an engine with 50 horsepower should not be imagined as being pulled by 50 horses, but rather by about 35 horses. The unit (ps) for horsepower was first used by the Germans and remains in use today.

What to Do When the Car Engine Won't Start?

Car engine won't start? Here are the possible causes and solutions: 1. Fuel flow obstruction: The main characteristic is the absence of fuel pressure in the engine's fuel supply line. This situation usually occurs on extremely cold mornings due to long-term dirt accumulation in the fuel line. At very low temperatures, water and debris can mix and block the fuel line, preventing the engine from starting. In such cases, an emergency solution is to move the car to a warmer environment, and it should start after a while. Alternatively, thoroughly cleaning the fuel line can permanently resolve the issue. 2. Spark plug clogging: If the vehicle manages to start despite clogged spark plugs, it will run roughly. The first step is to check the engine's condition. If irregular shaking occurs, it's likely caused by the spark plugs. Inspect the spark plugs for any issues and replace them if necessary. 3. Fuel pump pressure leakage: After prolonged use, the fuel pump may experience wear, leading to reduced fuel supply pressure and difficulty in ignition. Replacing the fuel pump can solve the problem.
