Do Tires Need to Be Replaced if They Have Cracks?

If there are minor cracks on car tires, determine whether they need replacement based on the following criteria: 1. Outer edge wear: If significant wear is observed on the outer edge of the tire when viewed in the direction of travel, it indicates the tire is frequently underinflated (insufficient pressure). 2. Convex and wavy wear: If the tread shows convex wear on both sides and wavy wear around the circumference, it suggests severe wear in components such as shock absorbers, bearings, or ball joints. 3. Even surface wear: If the wear has reached the standard tread depth (1.6 mm for tires narrower than 1.75 mm, or 2 mm for wider tires), replacement is necessary. 4. Inner tire wear: If the inner side of the tire is worn and the outer edges appear jagged.

What is the operating temperature of motorcycle engine oil?

Motorcycle engine oil operates at a temperature of 150 degrees Celsius. Motorcycle engine oil usage: Generally, motorcycles use synthetic engine oil to lubricate the moving metal components of the engine. For a new motorcycle during the break-in period, the first oil change is typically required after 500 to 1000 kilometers, and thereafter, the oil should be changed every 2000 kilometers. Motorcycle maintenance precautions: Always allow the engine to cool down before washing. Sudden rinsing of the engine, exhaust pipe, and other components with cold water can damage the oil seals in various parts, leading to engine oil leakage and component rusting. It is best to use a cloth to wipe clean areas such as the headlights, left and right handrails, ignition switch, exhaust pipe outlet, horn, spark plug, air filter, and battery. Otherwise, it may easily cause short circuits or electrical leakage.

Can I upgrade from a C3 driver's license to a C1 after 13 years?

Can I upgrade from a C3 driver's license to a C1 after 13 years? Yes, you can upgrade from a C3 driver's license to a C1 as long as you have not accumulated 12 penalty points in the current and previous scoring cycles. Steps to apply for the upgrade: You need to bring your motor vehicle driver's license and ID card to a local driving school to register for the upgrade. You will need to undergo training and pass the relevant subject exams. Upon passing, you will be issued a C1 motor vehicle driver's license. This upgrade process is identical to obtaining a new license. Driver's license usage notes: You must drive vehicles according to the permitted models specified on your driver's license. Always carry your driver's license when driving. If your driver's license is lost, you cannot drive and must immediately apply for a replacement at the vehicle management office. Also, pay attention to the renewal deadline for your driver's license—it can only be renewed in advance, not delayed.

How to Read a Car's Oil Pressure Gauge?

First, check if the oil pressure gauge returns to zero. When the engine is stationary and there is no oil pressure, the oil pressure gauge should return to zero because the oil pump is a mechanical pump, so the oil pressure increases as the engine speed rises. Therefore, the higher the engine speed, the higher the oil pressure supplied by the oil pump. Below is an introduction to engine oil pressure: 1. The level of engine oil pressure, as measured by a turbine flow meter, indicates the condition of the lubrication system. Whether the lubrication system is functioning normally can also be reflected in the oil pressure gauge. If the oil pressure gauge shows an abnormal reading, stop the vehicle immediately and inspect the issue. 2. If the oil pressure remains consistently low—whether at low or high speeds, low or high temperatures—and the oil pressure gauge always indicates below 0.1Mpa accompanied by the oil pressure warning light flashing, this indicates excessively low oil pressure.

How many points are deducted for driving with both hands off the steering wheel?

Driving with both hands off the steering wheel results in a deduction of 6 points and a fine. The following situations will result in a 12-point deduction: Reversing, driving in the opposite direction, or making a U-turn across the central divider on a highway; driving a motor vehicle at a speed exceeding 50% of the prescribed limit; drunk driving leads to a 6-month license suspension and a fine; driving under the influence results in the revocation of the motor vehicle driving license and criminal liability; no reapplication for a motor vehicle driving license within five years. Driving precautions: When driving normally, do not answer phone calls or smoke while driving, and keep both hands on the steering wheel. Many drivers answer phone calls or smoke while driving. If caught by traffic cameras, points will be deducted and fines imposed. Do not listen to music with headphones while driving, as this prevents hearing honking sounds outside the vehicle and severely compromises driving safety.

What is the brake structure of a motorcycle?

Motorcycle brake structure consists of a brake frame, brake components, and an operating device. Motorcycle Brake: The brake, commonly known as the stopping or decelerating mechanical component in machinery, is a crucial part ensuring the safe operation of a motorcycle and enabling it to come to a stable stop in the shortest possible time. Generally, for motorcycles with a displacement of less than 125ml, both front and rear wheels use drum brakes. For displacements between 125ml and 250ml, the front wheel employs a hydraulic brake, while the rear wheel uses a drum brake. Motorcycles with a displacement exceeding 250ml typically feature hydraulic brakes on both front and rear wheels. Drum Brake: Motorcycle drum brakes are mechanical brakes that can be used on the front wheel, rear wheel, or both. There are two types of drum brakes used in motorcycles: single-cam and double-cam. A motorcycle drum brake is composed of brake shoes, a brake cam, a brake drum, a brake arm, a brake drum cover, return springs, and a support shaft, among other components. In a drum brake system, the brake drum is mounted together with the wheel and rotates with it. The brake shoes are driven by the brake cam, and under the action of the return springs, the two brake shoes press tightly against the cam.
