When driving on the highway, the tire pressure can be slightly increased. Generally, the recommended tire pressure for most vehicles is around 220-260 kPa, and it is advisable to inflate the tires to approximately 250 or 260 kPa. Below is relevant information about tire pressure for highway driving: 1. Consequences of low tire pressure on highways: If the tire pressure is too low during highway driving, it can cause excessive deformation of the tire cord layers. As speed increases, severe cases may lead to standing wave phenomena in the tires, resulting in blowouts (the fatality rate from highway tire blowouts is nearly 100%). 2. Introduction to tire pressure: Tire pressure can be considered the lifeline of a tire. 'Tire pressure' refers to the air pressure inside the tire. Both excessively high and low tire pressure can affect the service life of the tire.

What Causes Vibration While Driving a Car?

Here are the specific reasons for body vibration while driving a car: 1. Wheel balancing issue: A car wheel consists of a tire and a rim. When there's a problem with wheel balancing, it means the wheel isn't in a balanced state during high-speed driving. If the balancing data is incorrect, the wheel's rotation center will deviate, causing vibration. 2. Rim problem: If the car's rims have suffered impacts during previous driving, they may become deformed. This deformation can also cause wheel vibration during driving. 3. Chassis component issues: This typically occurs in vehicles with poor post-accident repairs. The impact from an accident can affect chassis components, leading to vibration as well.

Can the license plate be retained after changing cars?

After changing cars, the original license plate can be retained. Below is the relevant introduction about the conditions for retaining the original license plate: 1. Timely application: Within one year after transferring the old car to someone else or canceling it, the original license plate will be reserved for the owner. As long as an application is made to the vehicle management office to use the original license plate during this period, the original license plate can be assigned to the newly purchased car or used car. After one year, the license plate will be re-entered into the selection pool and released to the public. 2. The original license plate must have been used for more than one year: Previously, the license plate had to be used for more than three years to be retained, so many car owners who wanted to change cars waited for three years before changing to retain the license plate. Now, as long as it has been used for more than one year, an application can be made to retain it. 3. All violations and accidents related to the original car must be settled: If there were road violations or penalties while driving the original vehicle, all fines must be paid, and there should be no unresolved traffic accidents, before applying to retain the original license plate number.
