You can find the size and dimensions of a car tire by checking the data on the sidewall of the tire. Here are the relevant details: 1. Wheel rim size: Generally, for the same car model with different configurations produced by manufacturers, the lower-end versions may sometimes use a smaller wheel rim size, but the tire's aspect ratio will also increase, resulting in minimal overall difference. Larger wheel rims can increase ground clearance and improve ride comfort. 2. Classification by type: Tires can be divided into full-size spare tires and non-full-size spare tires. A full-size spare tire has the same specifications as the four original tires on the car and uses the same wheel rim as the original wheels. A non-full-size spare tire is narrower in width or has a smaller wheel rim size, usually made of steel rims, and comes with speed restrictions (maximum speed not exceeding 80 km/h). It can only serve as a temporary replacement for the original tire.

Will ETC be subject to fraudulent charges?

Applying for ETC will not result in fraudulent charges, as the vast majority of ETC systems are very secure. To prevent ETC from being fraudulently charged, car owners are advised to: 1. Set a fixed limit for the ETC at the bank, and avoid setting it too high; 2. Remove the ETC card when leaving the vehicle; 3. ETC is an IC card that can only be settled in ETC scenarios, so try not to bind other bank cards when applying. The ETC system uses automatic vehicle identification technology to complete wireless data communication between the vehicle and the toll station, enabling automatic vehicle sensing and identification and the exchange of relevant toll data. It uses a computer network to process toll data, achieving a fully automatic electronic toll collection system without the need for stopping or setting up toll booths.

What Should Be Noted During the Overtaking Process While Driving?

During the overtaking process, forced overtaking is prohibited. If the vehicle ahead does not yield speed or lane due to certain reasons, forced overtaking should not be attempted. When there is insufficient safe distance ahead of the vehicle in front, do not forcibly squeeze in or push against it. Maintain a smooth overtaking path. Before overtaking, move into the left lane in advance, and delay returning to the right lane after overtaking, keeping the driving trajectory basically parallel to the vehicle being overtaken. Always pay attention to maintaining a safe distance from the overtaken vehicle before, during, and after overtaking. If an obstacle is detected on the left side during overtaking and the lateral distance is too small, potentially causing a squeeze or scrape, quickly decelerate, abort the overtaking, and wait for another opportunity. However, use the brake cautiously to prevent skidding. Key considerations for overtaking include: timing the overtake correctly. Often, it's safer to overtake when there are fewer vehicles ahead and behind and the road conditions are good. Remember to use the turn signal—activate the left turn signal to alert the vehicle behind that you intend to overtake, and quickly switch to the right turn signal after overtaking to return to the normal lane. Use the horn appropriately. Depending on the situation, honk the horn to alert the vehicle ahead of your intention to overtake, prompting them to yield. Utilize high beams and hazard lights effectively. Proper use of high beams and hazard lights can alert the vehicle ahead that you are overtaking and also remind oncoming vehicles to stay safe.
