When picking up a new car, it is essential to conduct a comprehensive inspection of the vehicle. First and foremost, pay attention to a set of numbers on the outer sidewall of the tires, which indicate the manufacturing date of the tires. Generally, the time from production to warehousing for tires should not exceed 3 years, and the usage time should not exceed 8 years. Tires have markings on them. For retreaded tires, these markings are usually stickers that can be rubbed off with a finger, whereas the markings on new tires cannot be rubbed off. Carefully inspect the tires for any scratches or wear. If the vehicle has been driven, the wear on the tires will be quite noticeable.

As someone who frequently works on cars, I know identifying original tires isn't that difficult. The key is to check the markings on the tire sidewall: OEM tires often have a special OEM code, which is a unique serial number that can be matched in the vehicle manual. The brand should also be correct, like Bridgestone tires for a Toyota. Additionally, details such as the size (e.g., 215/55R17) and speed rating (e.g., H) should match the factory specifications. I also pay attention to the tire's production date code, usually a four-digit number indicating the week and year, ensuring the tires are of the same age. OEM tires are specifically designed for the vehicle, offering better grip and fuel efficiency, so I regularly check for even wear. If unsure, you can visit a dealership to verify the vehicle records. After all, maintaining original parts enhances handling safety and provides peace of mind on long trips.

Why Should New Cars Be Driven on the Highway?

There are two main reasons for taking a new car on a highway run. The first reason is to break in the engine, allowing the new pistons and camshaft inside the engine to experience their first rapid operation. The second reason is to better adapt to high-speed operation, giving the transmission gears a chance to adjust to high-speed rotation, ensuring smoother meshing between the new gears. Here are some precautions for breaking in a new car on the highway: Drive after changing the engine oil: Breaking in on the highway requires not only skill but also proper timing. The quality of the engine oil is a direct factor affecting the engine. Therefore, it is essential not to drive at high speeds before changing the oil. During high-speed driving, the engine operates at high RPMs, leading to maximum mechanical wear. The first batch of oil contains a significant amount of metal debris and other impurities. Using oil with such debris for high-speed driving can greatly increase engine wear and even cause abnormal wear. As a result, the car will not be in optimal condition after the break-in period. Avoid driving at maximum speed: Breaking in on the highway is meant to gently condition various components of the vehicle. It is crucial not to drive at the car's maximum speed, as this will not achieve the goal of breaking in and may instead cause other issues due to excessive wear on the new car. Driving at speeds between 100–120 km/h is sufficient; there is no need to push the car to 150 km/h or 200 km/h.

What is the tire model for the GAC Honda Lingpai?

The Honda Lingpai has two tire sizes: 215/55R16 and 215/50R17. In 215/55R16, the first number 215 represents the tire width of 215MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 16 stands for the rim diameter of 16 inches. The letter "R" in the middle denotes a radial tire. In 215/50R17, the first number 215 represents the tire width of 215MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 17 stands for the rim diameter of 17 inches. The letter "R" in the middle denotes a radial tire. The tire brands for the Honda Lingpai are Linglong and Maxxis, featuring a petal-style wheel design, with the spare tire being non-full size. If you want to replace the tires yourself, follow these steps: Take out the spare tire and jack, place the jack under the car frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car, making sure the jack is positioned under the vehicle and at a right angle to the ground; Remove the hub cap, loosen the nuts counterclockwise, but do not fully unscrew them—just enough to eliminate resistance. Keeping the tire on the ground when first loosening the nuts ensures the nuts turn, not the tire; Turn the nuts counterclockwise until loose, repeat for all lug nuts, then completely remove them; Place the new tire on the hub, carefully aligning the tire rim with the wheel bolts, install the lug nuts, tighten them by hand until all nuts are hidden, completing the tire replacement. Besides the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed the tire can carry a specified load under specified conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Shows the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".

What is the wading depth test of the new X-Trail in meters?

The maximum wading depth of the new X-Trail is 400mm. The wading depth of the new X-Trail is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the new X-Trail is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, the auto start-stop function must be turned off to prevent the engine from automatically restarting after stalling in the water, which could cause severe damage due to water intake. Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Observe the path taken by other vehicles and follow it at a low speed, avoiding sudden acceleration or deceleration. For roads prone to waterlogging, observe warning water level markers, trees, and reference points like the wheels and doors of other vehicles to judge the water depth before deciding whether to proceed. Be aware of your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not enter the water recklessly; choose an alternative route instead.

What happens if the tire pressure is too high?

Tire pressure that is too high can affect vehicle performance, tire lifespan, and even compromise driving safety. Excessive tire pressure increases tire rigidity, reduces deformation and contact area with the ground, which can accelerate wear on the central tread and shorten tire lifespan. Moreover, overly high pressure makes tires excessively hard, negatively impacting ride comfort. When tire pressure is too high, deflation is necessary. If you have a dial-type tire pressure gauge, you can unscrew the tire valve cap, locate the valve core, press it gently, and simultaneously press the deflation valve while monitoring the gauge until the pressure returns to normal levels.
