What is the difference between 215 and 225 tires?

Can a touch-up pen be used for exposed primer?

Exposed primer cannot be directly repaired with a touch-up pen. For minor scratches, a touch-up pen can be used, but it only covers the color paint layer. If the damage reaches the primer, a touch-up pen will have difficulty repairing it effectively. It is recommended to visit a 4S shop or a professional repair shop for spray painting repair. Basic characteristics of touch-up pens: 1. Quick-drying: Due to usage environment constraints, touch-up pens must have a quick-drying feature at room temperature; otherwise, they may cause dripping or attract dust, affecting appearance. 2. Versatility: Touch-up pens are formulated with standard colors and have a certain level of versatility, but they cannot perfectly match vehicles with varying degrees of aging. For larger, longer, or deeper scratches, touch-up pens can only provide temporary concealment and cannot achieve the same effect as professional paint repair.

What to Do If a Tire Gets a Nail Puncture?

If a car tire is punctured by a nail and there is no air leakage or the leakage is very slow, you can drive at a low speed to the nearest repair shop for inspection. However, if the air leakage is severe, you should not continue driving. Instead, replace it with a spare tire or call for roadside assistance. Continuing to drive with severe air leakage can cause excessive damage to the tire due to over-compression, and in worse cases, it may even lead to wheel rim deformation. Below are the detailed guidelines: 1. Severe Air Leakage: If the tire is losing air rapidly, do not continue driving. Park the vehicle in a safe location immediately and call for assistance or replace it with a spare tire to reach the nearest repair shop. Continuing to drive under such conditions can cause irreversible damage to the tire's inner lining and the wheel rim, leading to more than just a simple tire repair. It can also significantly affect the vehicle's handling, especially in rainy conditions where it increases the risk of skidding. 2. Slow Air Leakage: If the tire is leaking air slowly, you may drive at a low speed to the nearest repair shop. It is advisable to plan your route in advance and locate the nearest auto repair shop to minimize travel distance. However, if the nearest repair shop is too far away, it is better not to take the risk, as driving with a leaking tire poses safety hazards. 3. No Air Leakage: If the tire is punctured but shows no signs of air leakage, you can continue using it temporarily. However, ignoring the issue for too long can compromise driving safety. Most modern tires are tubeless (vacuum tires), meaning they lack an inner tube. If the puncture is left untreated for an extended period, the damage may worsen, leading to cracks or even a sudden blowout. Therefore, even if there is no air leakage, it is essential to visit a repair shop as soon as possible for proper inspection and repair.

Can You Make a U-Turn at a Red Light Intersection?

If the U-turn signal is red, you must wait to make a U-turn; otherwise, it will be considered running a red light. According to the "Road Traffic Safety Law," this offense carries a penalty of 6 demerit points and a fine of 200 yuan. If there is no U-turn signal, and the gap is marked with a dashed line, the U-turn is not affected by traffic signals and does not require crossing the pedestrian crosswalk. However, if the gap is marked with a solid line, the U-turn must cross the pedestrian crosswalk and is subject to the left-turn signal. Making a direct U-turn may result in being photographed or penalized by on-site traffic police. When making a U-turn that requires crossing the pedestrian crosswalk, you must yield to pedestrians: If pedestrians are walking on the right side of the crosswalk and have not reached the centerline of the road, vehicles on the left side should slow down and proceed only after ensuring safety. If pedestrians are waiting outside the boundary of the motorized and non-motorized lanes and have not entered the roadway, vehicles should slow down and proceed only after ensuring safety. If pedestrians cross the boundary between the motorized and non-motorized lanes, vehicles failing to stop and yield are committing a violation and should be penalized. If pedestrians enter the motorized lane (Lane A) along the crosswalk, vehicles in Lane B should slow down and proceed only after ensuring safety. Vehicles in Lane A failing to stop and yield are committing a violation and should be penalized. If pedestrians waiting at the centerline of the road do not enter the motorized lane, vehicles failing to stop and yield are committing a violation and should be penalized. If pedestrians cross the centerline of the road and enter the motorized lane, vehicles failing to stop and yield are committing a violation and should be penalized. If the road is divided by a green belt and pedestrians are waiting in the middle of the road, vehicles must slow down and proceed only after ensuring safety. Scenarios where U-turns are allowed: If there is a U-turn sign at the intersection, you can make a U-turn. If there is a U-turn signal, follow the signal's instructions. If there is no signal, make the U-turn based on the specific situation, ensuring it does not interfere with other vehicles or pedestrians. If there is no explicit prohibition of U-turns or left turns at the intersection, you can make a U-turn. "No explicit prohibition" means there are no "No U-turn" or "No Left Turn" signs, and the centerline is not solid. U-turns are also allowed in yellow grid zones. Yellow grid lines indicate no-stopping zones at intersections prone to congestion, important entrances, or other designated areas. Parking (including waiting at traffic lights) in these zones is a violation. However, U-turns are permitted in yellow grid zones unless there is a central barrier. If there is a U-turn signal at the intersection, follow the signal—only proceed on green. If signs allow U-turns but prohibit left turns, note that "No U-turn" is not the same as "No Left Turn." Precautions when making a U-turn at an intersection: Observe road markings. If the line is solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable location. If there is a "No Left Turn" sign, even without a "No U-turn" sign, U-turns are not allowed because U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. U-turns from the second left-turn lane are not permitted. Always yield to oncoming traffic before making a U-turn to avoid accidents and full liability. Near the intersection stop line, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow. If it has a straight arrow, U-turns are prohibited even without explicit "No U-turn" signs.

Can 10W/30 be used in summer?

10W/30 engine oil can be used in summer, but it is not recommended for vehicles that frequently engage in long-distance high-speed driving. If the engine is to be continuously operated for long-distance high-speed driving, it is advisable to use engine oil with a higher viscosity grade to avoid engine damage. Here is additional information: 1. The number before W: The number before W refers to the viscosity of the engine oil at low temperatures. The smaller the number, the better the low-temperature fluidity of the oil, and the better the protection for the engine during cold starts. 2. The number after W: The number after W indicates the viscosity grade of the oil at 100°C. The larger the number, the higher the viscosity grade and the better the protective effect.

What does MTC on highways mean?

MTC stands for Manual Toll Collection, a semi-automatic highway toll collection system. MTC is a relatively traditional highway toll system, and together with ETC (Electronic Toll Collection), it belongs to the intelligent transportation system. Additional information: 1. Introduction: MTC (Manual Toll Collection Lane) is the existing manual toll collection system. The MTC lane consists of an Automatic Vehicle Classification system (AVC), card reader devices, display equipment, video surveillance, automatic barriers, and computer software systems. The card reader can be either contact or contactless. 2. Features: When a vehicle enters the MTC lane, the Automatic Vehicle Classification system (AVC) automatically classifies the vehicle information and then informs the software system about the type of vehicle. Based on this information, the software system instructs the card reader on the amount of toll to be charged. Once the transaction is completed, the software system sends a command to the automatic barrier to allow the vehicle to pass, completing the toll collection process.

Can Different Grades of Gasoline Be Mixed?

92-octane gasoline and 95-octane gasoline cannot be mixed because they have different isooctane contents. 92-octane gasoline is suitable for engines with low compression ratios, while 95-octane gasoline is suitable for engines with high compression ratios. If 92-octane gasoline is added to a car that requires 95-octane gasoline, abnormal combustion may occur, leading to engine knocking. Knocking not only damages the combustion chamber but also directly affects the normal operation of the engine, and in severe cases, it may cause engine damage. If 95-octane gasoline is added to a car that requires 92-octane gasoline, although it will not damage the engine, 95-octane gasoline is more expensive than 92-octane gasoline, resulting in unnecessary costs. Differences between 92, 95, and 98-octane gasoline: Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, and its octane rating is set at 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, so its octane rating is set at 0. If the gasoline is labeled as 92-octane, it means that the gasoline has the same anti-knock properties as standard gasoline containing 92% isooctane and 8% n-heptane. The same principle applies to 95 and 98-octane gasoline. What to do if the wrong gasoline is added: If a higher octane gasoline than required is added—for example, adding 95-octane gasoline when 92-octane is specified—simply use up the gasoline and then refill with 92-octane gasoline. If a lower octane gasoline than required is added—for example, adding 92-octane gasoline when 95-octane is specified—you can add a high anti-knock fuel additive. Alternatively, you can drain the gasoline and refill with 95-octane gasoline. To find out which gasoline grade your car requires, you can refer to the car's user manual or check the fuel grade labeled on the fuel tank cap.
