What is the definition of tire specifications?

The parameters displayed on tire specifications represent the tire width, aspect ratio, maximum speed the tire can withstand, tire type, and applicable tire size. The functions of tires are as follows: 1. Support the entire weight of the vehicle and bear the load of the car. 2. Transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface. 3. Reduce and absorb vibrations and impact forces during driving, preventing severe vibrations and premature damage to automotive components. 4. Adapt to the high-speed performance of the vehicle and reduce noise during driving, ensuring driving safety, handling stability, comfort, and energy-saving economy.

What does 'media' mean in cars?

In cars, 'media' refers to the multimedia audio and video playback function, commonly understood as the capability to play audio and video files, which is part of the car's entertainment features. Generally, pressing the 'MEDIA' button will directly take you to the relevant interface to use the multimedia player. Nowadays, most cars allow all operations to be performed through the central control screen, much like operating a smartphone or tablet. A car audio system typically consists of four main components: the source unit, which includes front-mounted hosts (installed on the dashboard) that provide radio, cassette, CD, VCD, MD, MP3, DVD, and TV playback, as well as rear-mounted CD, VCD, and DVD changers (installed in the trunk). In recent years, this has expanded to include digital media such as USB, HD, Memory Stick, and iPod. The amplification section usually refers to the power amplifier that processes and amplifies signals from different audio and video sources, including pre-amplifiers and post-amplifiers. The speaker section typically includes front and rear field speakers and mid-low frequency speakers. The wiring section usually comprises signal cables, speaker wires, and power cables.
