If the damage is minor, it's acceptable to drive on highways. However, for larger ruptures, it's recommended to avoid highway driving or replace the tire before doing so for safety reasons. Generally, if the damaged area exceeds 6mm, it may compromise the cord layer, making any type of tire repair unsuitable for highway use due to the risk of a blowout. More details are as follows: 1. Hot patching should be avoided as it causes significant damage to the tire. External plug repairs are unsafe and not advisable for highway use. If the puncture width exceeds 6mm, or if the same tire has been repaired more than twice, it's best to refrain from highway driving. 2. Tires are one of the most critical components of a vehicle, serving several essential functions: supporting the vehicle's entire weight and bearing its load; transmitting traction and braking torque to ensure adhesion between the wheels and the road; absorbing shocks and vibrations during driving to protect vehicle components from excessive wear and premature damage; enhancing high-speed performance while reducing noise; and ensuring safety, handling stability, comfort, and fuel efficiency.

What does eco mean on a car?

Eco on a car refers to the fuel-saving mode. When this mode is activated, the vehicle's onboard computer control unit makes adjustments to the operating system based on a comprehensive analysis of driving data such as vehicle speed, engine RPM, and transmission gear position. The vehicle will automatically match the appropriate gear and RPM to reduce fuel consumption. Cars generally have three driving modes: 1. Eco mode: A more economical and fuel-efficient driving style, suitable for daily commuting; 2. Normal mode: Designed to maintain consistent power while achieving better fuel economy. In normal mode, the throttle response is balanced, providing a simpler and more comfortable driving experience; 3. Sport mode: Increases engine RPM or quickly downshifts to deliver instant bursts of greater power.

What is the reason for the ABS light on the car dashboard?

Car dashboard ABS light is on because the control system has detected a fault that requires inspection. ABS is the Anti-lock Braking System. This light should briefly illuminate for a few seconds during startup - it will automatically turn off after system self-check completes successfully. During driving, if you stomp the brakes rapidly to the floor, ABS will activate (with light illumination) and deactivate (light turns off) when releasing the brakes. ABS (Anti-lock Braking System) is a technology developed by Robert Bosch GmbH for motorcycles and automobiles that prevents wheel lock-up, generally increases braking distance, and enhances vehicle safety.
