What does 3T mean on car tires?

3T on car tires refers to the treadwear index, traction index, and temperature index. The treadwear index reflects the tire's wear resistance - the higher the number, the more wear-resistant the tire is, but the harder the rubber becomes, resulting in poorer comfort. Conversely, a lower number indicates less wear resistance, softer rubber, and better comfort. The sidewall of a tire actually contains a lot of information, such as speed rating, recommended tire pressure, specifications and dimensions, and production date. Tires are circular elastic rubber products mounted on various vehicles or machinery that roll on the ground. They are usually installed on metal rims to support the vehicle body, cushion external impacts, maintain contact with the road surface, and ensure driving performance. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperature effects during driving, so they must have high load-bearing capacity, traction performance, and cushioning performance.

How to Determine When to Replace Car Tires?

Methods to determine when to replace car tires: 1. Check if the tread wear is close to the wear indicators; 2. Look at the tire production date to confirm if it has expired; 3. Inspect the tires for any abnormal phenomena such as cracks or bulges. Car tire maintenance methods: 1. Regularly check tire pressure; 2. Adjust tire pressure according to different seasons; 3. Pay attention to whether the wear has reached the wear markers; 4. Rotate the positions of the tires after driving for a certain period; 5. Regularly check front wheel alignment; 6. Be mindful of your driving style. The purpose of car tire maintenance is to slow down tire aging and extend their service life.

What engine does the CS75 Glory Million Edition have?

Changan CS75 Glory Million Edition is equipped with the Blue Whale 1.5T engine across the entire lineup, with a maximum power of 131kW and a peak torque of 265Nm. This engine is the same as the 1.5T engine in the CS75 PLUS. The function of an automobile engine: It converts the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. How an automobile engine works: Air and gasoline are mixed in a certain proportion to form a combustible mixture. The intake stroke draws the mixture into the cylinder, where it is compressed and ignited, generating thermal energy. The high-temperature, high-pressure gas acts on the top of the piston, driving it to perform reciprocating linear motion. Mechanical energy is then output externally through the connecting rod, crankshaft, and flywheel mechanism. Automobile engine maintenance methods: Using anti-wear agents for maintenance: Engine anti-wear agents are oil additives with stronger adhesion than engine oil, better heat and corrosion resistance. They can adhere to the cylinder walls to form a protective film, enhancing lubrication and repairing scratches on the cylinder walls, smoothing rough surfaces to ensure normal high-speed operation of the engine, providing protection and repair. Using high-quality engine oil: Engine oil, the lubricant for the engine, plays roles in lubrication, cleaning, cooling, sealing, and reducing wear. Only by using qualified lubricating oil can the wear of engine parts be reduced, extending the engine's service life. Using qualified coolant: Automobile engines rely on the radiator to cool down; otherwise, the engine may overheat, causing fatal damage. Therefore, it is essential to ensure the coolant level in the radiator is maintained at a normal level and to choose high-quality coolant. Especially in winter, the appropriate coolant should be selected based on the ambient temperature. In regular maintenance, the engine antifreeze should be replaced every year. Regularly removing carbon deposits from the car: It is important to prevent carbon deposit formation by driving at high speeds when possible, appropriately increasing the RPM during gear shifts, avoiding prolonged idling, and using clean gasoline. Good driving habits can reduce carbon deposit formation. Timely replacement of the car's three filters: The air filter ensures a clean environment for the car engine, the fuel filter purifies the fuel, and the oil filter prevents the mixing of oxidized carbon deposits under dust and high temperatures, extending the engine's lifespan.

What does a tire pressure of 220kpa mean?

Tire pressure of 220kpa means the tire is at 2.2 atmospheric pressure. A tire pressure of 220kpa is the designed value for the tire pressure, and it is necessary to inflate the tire to 220kpa during normal driving to ensure the vehicle's performance. Different vehicles may have slightly different designed tire pressures. There are two types of car tire pressures: 1. Low-pressure tires: The inflation pressure ranges from 0.1471 to 0.490MPa. Low-pressure tires are generally used in private cars, and the typical inflation pressure for family cars is between 0.2 to 0.25MPa. 2. High-pressure tires: The inflation pressure ranges from 0.5 to 0.7MPa. High-pressure tires are suitable for large trucks or passenger vehicles, with an inflation pressure usually around 0.5MPa.

Where to Check the Tire Production Year?

Tire production year is marked on the sidewall of the tire. Manufacturers use a four-digit code to indicate the production date, where the first two digits represent the week of production and the last two digits indicate the year. You can locate this four-digit code by carefully inspecting the tire sidewall. Tires are crucial components of a vehicle, directly affecting driving stability and safety. They are the only parts of a car that make contact with the road surface. Being rubber products, tires are subject to aging with prolonged use, hence requiring regular replacement. Under normal circumstances, tires installed on a vehicle can be used for four years. It's recommended that car owners replace their tires every four years.

Can a Bulging Tire Be Repaired?

Bulging tires cannot be repaired and must be replaced. Tires are a crucial component of a vehicle, made of rubber, which deteriorates over time with prolonged use. Tire maintenance methods include: 1. Monthly tire pressure checks; 2. Regularly monitoring tire wear indicators; 3. Paying attention to the tire's expiration date; 4. Prioritizing four-wheel rotation. Situations where tire damage is irreparable: 1. A puncture on the tread with a hole diameter exceeding 6mm; 2. Punctures, cracks, or air leaks on the tire shoulder or sidewall; 3. Run-flat tires with sidewall reinforcement technology driven a certain distance at low pressure after a puncture and air loss; 4. Regular tires driven a certain distance near zero pressure after a puncture and air loss.
