Can a Spare Tire Be Used on the Road?

Spare tires can be used on the road. A spare tire refers to an additional tire for a car, which usually has the same specifications as the original tires. However, some vehicles use spare tires with special-colored rims, compact spares, folding spares, or run-flat tires to remind the owner to inspect and replace the faulty tire promptly. Below are the functions of car tires: 1. Supporting the vehicle's full weight: They bear the vehicle's load and transmit forces and torques in other directions. 2. Transmitting traction and braking torque: They ensure good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and off-road performance. They also work with the suspension to absorb shocks and dampen vibrations during driving. 3. Preventing damage to vehicle components: They protect against severe vibrations and premature wear, enhance high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.

Which Vehicles Require Biannual Inspections?

Operational passenger vehicles over 5 years old require inspection every 6 months, totaling twice a year. Trucks and large/medium-sized non-operational passenger vehicles over 10 years old need inspection every 6 months, twice annually. Small and mini non-operational passenger vehicles exceeding 15 years require semiannual inspections, twice yearly. Below are motor vehicle annual inspection details: 1. Document verification: Check for vehicle manual, certificate of compliance (import vehicles' commodity inspection certificate), and completeness of factory inspection marks on the vehicle body. 2. Dimensional measurement: Measure internal/external contours including wheelbase and axle track. Specific measurements include length, width, height, cargo compartment panel height/area, wheelbase, and axle track. 3. Complete modification registration form: Conduct item-by-item inspection per technical standards. Upon passing, fill out the "Initial Motor Vehicle Inspection Modification Registration Form" and document curb weight, load capacity, passenger capacity, and cabin occupancy as per manufacturer specifications.

What Causes Brake Friction Noise?

The causes of brake friction noise may include excessively hard brake pads, worn brake pads down to the backing plate, excessive wear of brake discs or drums, rusted brake calipers, stiff parking brake cables, slow return of the master cylinder, etc. It is necessary to visit a 4S shop for inspection and repair. Below is an introduction to brake pedal operation: 1. Introduction to brake pedal operation: Automobile brake pedal operation can be categorized into gradual braking (i.e., anticipatory braking), emergency braking, combined braking, and intermittent braking. Generally, during gradual braking and emergency braking, the clutch pedal should be fully depressed before the wheels lock up and the vehicle comes to a stop, to prevent the engine from stalling and facilitate speed readjustment. 2. Proper timing and force application in braking: Under normal circumstances, avoid stomping the brake pedal all at once. First, press the brake pedal, adjusting the foot pressure (i.e., increasing the force) as needed—apply quick and firm pressure when the speed is high, and light and steady pressure when the speed is low. Then, adjust the pressure increase or decrease based on various conditions.

What cleaning tools are used for interior cleaning?

Generally, the most commonly used full set of car interior cleaning tools includes: vacuum cleaner, towels, brushes, cleaning agents, cleaning gel, and dashboard wax. Preparing the above supplies can basically meet the daily cleaning needs of the interior. Relevant information is introduced as follows: Regular interior cleaning can create a good in-car environment and protect health. The carpet, seats, air vents, trunk, and other areas in the car interior often come into contact with humid air or water stains. In specific environments, these areas are most likely to breed bacteria, causing the interior to mold and emit foul odors, which not only affects the indoor air environment but also poses a threat to health. Cleaning, sterilizing, and deodorizing the interior can effectively prevent various contaminants from corroding the interior.

What is the age limit for applying for a small car driving license?

The age limit for applying for a small car driving license is 18 years old and above, with no upper limit. According to the new measures issued by the Traffic Management Bureau of the Ministry of Public Security, starting from November 20, 2020, the application for small car and small automatic transmission car driving licenses is open to those aged 18 and above, with the previous upper age limit of 70 years old abolished. For those aged 70 and above who apply for a driving license, additional ability tests such as memory, judgment, and reaction are required, and an annual physical examination is mandatory. Below is an introduction to the driving test subjects: 1. Subject 1: Also known as the theoretical test or driver theory test, it is part of the motor vehicle driving license assessment. 2. Subject 2: Also known as the small road test, it includes five test items: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve. 3. Subject 3: Also known as the big road test, it is the road driving skills test in the motor vehicle driver examination. 4. Subject 4: Also known as the theoretical test or driver theory test.

Which Motor Oil Viscosity Grade is the Highest?

W60 motor oil has the highest viscosity. The number following "W" indeed indicates the oil's viscosity at 100 degrees Celsius, with a larger number representing higher viscosity. The subsequent number primarily denotes the oil's high-temperature resistance performance target—the higher the value, the better the oil's protective function under high temperatures. Below are the functions of motor oil: 1. Friction Reduction: A sufficiently thick oil film separates the relatively sliding component surfaces, thereby reducing wear. 2. Sealing: Motor oil can form a sealing ring between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. 3. Rust Prevention: Lubricating oil adheres to component surfaces, protecting them from contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When pressure in the engine cylinder rises sharply, suddenly increasing the load on pistons, piston skirts, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: High-quality motor oil can carry carbon deposits, sludge, and worn metal particles from engine components back to the oil pan through circulation, flushing away contaminants generated on the working surfaces of the components via the flow of the lubricating oil.
