What does 215/50R17 tire mean?

215 indicates the tire width, which means the tire is 215mm wide. 50 represents the aspect ratio, which is the ratio of the tire height to the tire width, indicating that the tire height is 50% of the tire width. The smaller the number, the flatter the tire appears. R refers to the tire structure, indicating that this tire is of radial construction. 17 is the rim diameter, meaning the tire is suitable for 17-inch wheels. The aspect ratio refers to the ratio of the height from the rim to the tread and the maximum width of the tire cross-section, expressed as a percentage, i.e., the height as a percentage of the width. Notes on tire aspect ratio: The tires equipped when the vehicle leaves the factory are the best specifications selected by the manufacturer after repeated tests. If you want to replace tires of different sizes and specifications, it must be done under the guidance of professionals and not changed arbitrarily, as it may pose a risk to driving safety. High aspect ratio tires have long sidewalls and strong cushioning ability, which makes them relatively more comfortable, but they have poorer road feel and weaker lateral resistance during turns. Low aspect ratio and large inner diameter tires have short sidewalls and wide treads, resulting in a large contact area and high pressure-bearing capacity. They are very sensitive to road conditions and have strong lateral resistance during turns, enhancing vehicle handling. Tires are the only part of the car that comes into contact with the ground, affecting the vehicle's driving stability and safety. Tires are rubber products, and rubber products will age over time with prolonged use, so tires need to be replaced regularly. Generally, tires installed on a car can be used for four years. When purchasing new tires, be sure to check the production date. Typically, unused tires have a shelf life of three years. In addition to the model, tires are also marked with the following common data: Tire carcass ply material: Indicated by Chinese pinyin, such as M-cotton ply, R-rayon ply, N-nylon ply, G-steel ply, ZG-steel radial ply tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires from 4.8km/h to 300km/h. Commonly used speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim specification compatible with the tire. For practical use, such as: standard rim 5.00F. In daily use of tires, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves of the tire gradually become shallow. If the tread is worn flat, it will lose its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks may seem minor but can be a hidden danger for tire blowouts at high speeds. Additionally, promptly remove pebbles from the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the car near or in contact with petroleum products, acids, or other materials related to rubber deterioration. After parking, the driver should not turn the steering wheel, as this operation will accelerate tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and the pressure will increase. In this case, stop to dissipate heat. It is strictly forbidden to release pressure or splash water to cool down, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and emergency braking to prevent accelerated tread wear due to dragging between the tire and the ground.

How to Park an Automatic Transmission Vehicle on an Uphill Slope?

When parking an automatic transmission vehicle on an uphill slope, follow these three main steps: Step 1: Engage the handbrake. Step 2: Release the foot brake. Step 3: Press the foot brake, shift the gear to N (Neutral), and then to P (Park). If you engage the handbrake while still in D (Drive), the vehicle retains forward propulsion, similar to starting with the handbrake engaged. Additionally, when parking an automatic transmission vehicle on a slope, note that the P (Park) gear's locking mechanism relies on gear engagement inside the transmission. After parking, keep the foot brake pressed, engage the handbrake while shifting to N (Neutral), then release the foot brake to allow the vehicle to settle and the handbrake to take effect. Finally, press the foot brake again and shift to P (Park).

What are the differences between the 2016 and 2019 Tiida models?

The differences between the 2016 Tiida and the 2019 Tiida can be observed in four main aspects: First: Powertrain. The 2016 Tiida continues to use the 1.6L naturally aspirated engine paired with either a 5-speed manual or CVT transmission. The 2019 model still features the HR16 1.6L naturally aspirated engine, with a maximum power output of 93kW and peak torque of 154Nm. Second: Transmission. Both models are equipped with a 5-speed manual or CVT transmission. Third: Exterior. As a mid-cycle refresh, the 2016 Tiida adopts Nissan's latest "YOUNG NISSAN" design philosophy, transforming into a youthful and stylish hatchback. The 2019 Tiida retains the same exterior design as the previous model but enhances its technological features, including the addition of Dongfeng Nissan's "Intelligent Mobility+" connectivity system. Fourth: Interior. The 2019 Tiida inherits the design of the previous model with some refinements, such as a front-and-rear sliding center armrest and the inclusion of the "Intelligent Mobility+" system. The steering wheel design remains unchanged, the seats are the same, and the spacious interior continues to be a highlight. The 2019 model comes with a non-full-size spare tire, while the 2016 Tiida is equipped with a full-size spare tire.

What Does Continuously Variable Transmission Mean?

Continuously Variable Transmission (CVT) is a type of transmission in automatic vehicles, referring to a system that can continuously achieve any gear ratio within the transmission range. CVT allows for optimal matching between the drivetrain and engine conditions. To achieve CVT, three methods can be employed based on the transmission type: hydraulic transmission, electric transmission, and mechanical transmission. The difference between a CVT and a conventional automatic transmission lies in the elimination of complex and bulky gear combinations for speed variation. Instead, CVT uses only two sets of pulleys for speed variation, adjusting the speed by changing the contact radius of the belt between the driving and driven pulleys. Common types of CVTs include hydro-mechanical CVTs and metal belt-type CVTs (VDTcvt). Currently, more and more vehicle models in the domestic market are adopting CVT technology.

How to Renew a Temporary License Plate?

Temporary license plates can be reapplied for once they expire, but the vehicle management office may issue temporary license plates no more than three times. When using temporary license plates, the following three aspects should be noted: First: Local temporary plates can be extended up to three times, totaling a usage period of 21 days. Second: They can only be used within the city and must not be driven outside the designated area; otherwise, the vehicle will be treated as unlicensed. The procedure for extending the validity of a temporary license plate is the same as the initial application. The owner needs to provide identification, vehicle purchase invoice, new vehicle certificate, compulsory traffic insurance certificate, or import certificate and copies of relevant documents to the public security authority to apply for a temporary license plate. During the application, the starting and ending locations of the vehicle's use and the duration of the temporary plate must be specified. The process typically takes about one working day to complete and is postponed in case of holidays. Third: Expired temporary license plates must not be used on the road. If the vehicle has not been formally registered and continues to use an expired temporary license plate, it is equivalent to "driving a motor vehicle on the road without displaying a license plate."
