Should the Red and Yellow Dots on Tires Face Outward?

The yellow and red dots on tires should face outward. When installing tires, the side that should face outward is usually marked with the word 'outside'. The yellow dot indicates the lightest point of the tire, while the red dot represents the heaviest point. Here are some precautions regarding tire replacement: 1. The yellow and red dots should align with specific positions on the rim: There are slight variations in the manufacturing process, so the weight distribution around the tire is not uniform. 2. After replacing tires, it's essential to perform a dynamic balance on all four wheels: Without proper balancing, the wheels may vibrate or shake when driving at high speeds.

Why is the Accord D gear indicator light flashing continuously?

D gear is the forward gear, also known as the drive gear. In this gear, the transmission automatically shifts between 1st gear and overdrive based on speed and throttle conditions, and is used for normal road driving. The flashing gear indicator light indicates that the vehicle has detected an internal transmission fault, triggering a time-limited protection that restricts gear shifting or high-speed functions. The reasons for the continuous flashing of the Accord D gear indicator light include: 1. The steering wheel is in a locked position. 2. Poor signal from the 2nd gear clutch pressure switch causing the D position indicator to flash. 3. Excessive input from the shift solenoid. 4. Electrical control failure in the transmission.

Can a Car Designed for 92 Octane Use 95 Octane Gasoline?

92 octane cars are not recommended to use 95 octane gasoline. The specific reasons are as follows: 1. 95 octane and 92 octane gasoline have different iso-octane and n-heptane values, and mixing them may cause wear and tear to the vehicle. 2. Using 92 octane fuel in a 95 octane car can increase the frequency of engine knocking and accelerate engine wear. 3. 92 octane gasoline contains approximately 92% iso-octane and 8% n-heptane. Iso-octane has better anti-knock properties, while n-heptane has poorer anti-knock properties. Higher octane ratings indicate higher octane values, resulting in better anti-knock performance for the gasoline.
