What is the appropriate tire pressure for high-altitude areas?

High-altitude car tire pressure should be between 2.3~2.5. The following is relevant knowledge about car tires: Functions of tires: Car tires are one of the important components of a vehicle, directly contacting the road surface and working together with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness; maintaining excellent adhesion between wheels and road surfaces; improving traction, braking, and off-road capability; and bearing the weight of the vehicle. The crucial role tires play in automobiles is increasingly being recognized. Classification of tires: Full-size spare tire: A full-size spare tire has exactly the same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. Compact spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary replacement, limited to non-driven wheels, and with a maximum speed not exceeding 80km/h.

Can I switch back to 95 after adding 98?

After using 98-octane gasoline, you can switch back to 95-octane, but it's recommended to first completely use up the 98-octane fuel before refilling with 95-octane. Vehicle owners are advised not to frequently switch between different gasoline grades. Once you've selected a fuel type, it's best to 'stick with it' and consistently use the same grade over the long term. The differences between 98-octane and 95-octane gasoline are as follows: 1. Different octane ratings: The grade number only indicates the octane value of the gasoline. The octane value is determined by comparing the fuel's knock intensity with standard fuels (iso-octane and n-heptane), where the percentage volume of iso-octane in the standard fuel that produces equivalent knock intensity represents the sample's octane value; 2. Different anti-knock combustion capabilities: Higher octane values indicate better anti-knock combustion performance; 3. Price difference: Generally, higher-grade gasoline offers better quality, and consequently comes with a higher price.

What Causes the Thumping Noise When Coilover Suspension Goes Over Bumpy Roads?

The reasons for abnormal noise in car coilover suspension are: 1. Loose shock absorber mounting: Long-term vibration during driving can cause the fixing nuts to loosen, leading to abnormal noise from the shock absorber. Solution: Tighten the fixing nuts. 2. Insufficient oil in the shock absorber: Lack of oil can also cause abnormal noise. Check for oil leakage in the shock absorber. If there is leakage, it is recommended to directly replace the shock absorber. If there is no leakage, other components of the shock absorber system need to be inspected. 3. Worn rubber bushings: Wear in the rubber bushings at both ends of the shock absorber can create play at the mounting points, causing noise during driving. Replace the rubber bushings. 4. Deformed components: Deformation of the shock absorber piston rod, cylinder tube, or oil reservoir, or sticking of the piston rod can cause abnormal noise and lead to shock absorber failure, even causing safety hazards. Repair is not recommended (as it is very complicated); it is advised to replace the shock absorber.

Does passing through a yellow light count as running a red light?

According to Article 38 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China', when the yellow light at an intersection is flashing, vehicles that have already crossed the stop line may continue to pass. Passing through a yellow light after crossing the stop line does not count as running a red light. If the yellow light is already on and you continue to force your way through, being caught on camera in such a scenario will count as running a red light. According to the relevant provisions of Article 90 of the 'Regulations on the Handling Procedures for Road Traffic Safety Violations', motor vehicle drivers who do not follow traffic signals will be penalized with 6 demerit points and a fine of 200 yuan. Criteria for determining a red light violation: Electronic cameras will take 3 photos as the basis for determining a red light violation: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all 3 photos are present will it be considered a red light violation. If you stop the car after crossing the stop line when the red light is on, even if you have already crossed the line, it will not be considered running a red light but will be classified as stopping beyond the line. How to avoid running a red light while driving: When there are arrow signal lights, follow the arrow lights; otherwise, follow the circular lights; When the red light is on, the front of the vehicle must not cross the stop line; When the yellow light is on, the front of the vehicle must not cross the stop line; When the green light just starts flashing, if you are close and moving fast, you should proceed, as you might not be able to stop in time and cross the stop line; if you are far away, moving slowly, or the intersection is congested, you should stop; When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line or approach an intersection.

What is the size of a 195 tire in inches?

195 tire is 15 inches. Below is relevant knowledge about car tires: Functions of tires: Car tires are one of the important components of a vehicle, directly contacting the road surface. Together with the car suspension, they mitigate the impacts experienced during driving, ensuring good ride comfort and smoothness. They also ensure excellent adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The crucial role tires play in vehicles is increasingly being recognized. Classification of tires: Full-size spare tire: The specifications of a full-size spare tire are exactly the same as the other four tires on the vehicle, allowing it to replace any temporarily or permanently unusable tire. Compact spare tire (non-full-size spare): This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary replacement. It can only be used on non-driving wheels, and the maximum speed should not exceed 80km/h.

Why is there no sound when playing music via connected car Bluetooth?

There are several reasons why there might be no sound when your phone is connected to the car's Bluetooth: the volume on the car navigation system or phone is not turned on, the music playback programming on the phone is incompatible with the car model's pairing code, Bluetooth signal interference, or multimedia music is not enabled. Volume on the car navigation system or phone is not turned on: If the volume is not turned on, you won't hear any sound. The solution is to go to the phone's "Settings" - "Sound," find the "Media" option, and turn up the "Media" volume. The same applies to the car navigation system. Music playback programming on the phone is incompatible with the car model's pairing code: Some phones (e.g., iPhone) have music playback programming that is incompatible with certain car models' pairing codes, so you can only make calls but not listen to music. Solution: Try changing the Bluetooth playback frequency band to resolve the issue. Bluetooth signal interference: If the media audio on the phone is not turned off, it may cause Bluetooth signal interference. Solution: Go to the phone's Bluetooth settings and turn off the media audio while keeping the phone audio enabled. Multimedia music is not enabled: Another possible reason is that the multimedia music feature is not enabled on the car's Bluetooth. Solution: Find the multimedia option on the screen, enter it, and select Bluetooth to play music, which should solve the problem.
