How to Properly Match and Use Tires?

When installing tires on the same axle, they must be reasonably matched, paying attention to the "four same" principle (i.e., same brand, same specifications and size, same tread pattern, same air pressure standard). Below is a related introduction to tires: 1. Functions of tires: mainly include dry road grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet road grip, load capacity, handling performance, average wear, and mileage. 2. Cross-sectional structure of tires: can be roughly divided into 4 parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the rim to provide sealing. 3. Internal composition of tires: the interior of the tire is composed of multiple layers of different materials, including tread pattern, overlay, steel belt layer, stress absorption rubber strip, carcass ply layer, and inner liner.

Where is the OBD interface located on the Karry Youjin?

It is located slightly above and outward from the clutch pedal. Related content introduction: 1. Stylish front face: Modern yet stable, harmonious and unified, seamlessly integrated with the Karry logo, aesthetically pleasing and grand. 2. Design combination: The honeycomb-shaped U-shaped grille and radiator mesh design combination provides better ventilation and heat dissipation. The nose line extending from the grille to the engine hood effectively outlines the three-dimensional and layered feel of the entire engine hood, complemented by the large front windshield, making the vehicle appear more fluid and grand. The overall impression is more imposing, breaking away from the cramped and oppressive feeling of traditional microvans and adding a strong trendy vibe. 3. Body appearance: The Karry Youjin is a single-row extended micro-truck improved and designed based on the Karry Youyou. With a sturdy chassis and body structure design, a 2.5-meter-long cargo compartment, the widest cabin of 1.6 meters among micro-trucks, and a 5-leaf spring rear suspension, its load capacity reaches up to 980kg, fully meeting production needs.

At what level of wear must brake discs be replaced?

Brake disc replacement standard is around 2 millimeters. If the brake disc wear exceeds this standard, replacement should be considered. More knowledge about brake discs is as follows: 1. Brake disc: Simply put, it is a round disc that rotates when the vehicle moves. The brake caliper clamps the brake disc to generate braking force. When braking, it clamps the brake disc to slow down or stop the vehicle. Brake discs provide effective braking performance and are easier to maintain than drum brakes. 2. Front disc rear drum: Braking systems include disc brakes, drum brakes, and air brakes, with many vehicles using front disc and rear drum configurations. Many vehicles now use disc brakes on both front and rear. Because disc brakes dissipate heat better than drum brakes, they are less prone to thermal fade during high-speed braking, resulting in better high-speed braking performance. However, during low-speed cold braking, the braking effect is not as good as drum brakes.

Has the Hill Start Test Been Canceled?

Hill start test has been canceled. Here are the relevant details: 1. Skill assessment: The hill start and stop test evaluates a driver's ability to control a vehicle on an incline, accurately judge the vehicle's position, properly stop at a designated spot, and correctly use brakes, gears, and clutch to meet operational requirements when waiting for traffic clearance on slopes. 2. Automatic transmission vehicles: The hill start and stop test item has been removed from the Category 2 driving test for small automatic transmission vehicles, reducing the test items from 5 to 4. Additionally, the waiting period between tests for automatic transmission vehicles has been shortened from 30 days to 20 days after passing the Category 1 test.
