Tire replacement criteria are as follows: 1. Technical standard: When tread grooves are less than 1.6MM, tires should be replaced. If the tread wear indicator is exposed, it indicates that the groove depth is less than 1.6mm. The tread wear indicator is the raised part in the groove. Using tires with remaining groove depth below 1.6mm may result in sudden loss of traction and braking force in rainy conditions, as well as complete loss of traction in snowy conditions. 2. Tread standard: Tires that have been punctured more than 4 times on the tread; tires with punctured or damaged sidewalls; tires with tread punctures exceeding 4mm in diameter; tires with punctured shoulders. The sidewall rubber is thinner, and if the puncture hole is large or the rubber surface shows extensive rough granulation or bulging deformation, immediate replacement is necessary to prevent blowouts. 3. Mileage standard: Based on road conditions, 30,000-50,000 kilometers. For smooth asphalt roads, 50,000 kilometers; for rough gravel roads, 30,000 kilometers. When exceeding 30,000 kilometers, the tread friction coefficient is less than 50. In wet or snowy conditions, the tread's water drainage function decreases or is lost, with a friction coefficient below 15, making gravel roads prone to blowouts.

How to Replace Coolant for Nissan Sylphy?

Nissan Sylphy coolant replacement steps are: 1. Open the radiator cap, remove the engine undercover, open the radiator drain plug at the bottom of the radiator, then remove the radiator cap. Before unscrewing the radiator cap, turn it slowly to release accumulated pressure, then fully unscrew it; 2. Drain the old coolant, locate and open the coolant drain screw (usually located at the rear side of the engine), and use an air gun to blow out excess coolant; 3. Refill with new coolant. After tightening the drain screw, add new coolant through the filler port, generally not exceeding the MAX mark; 4. Install the radiator cap: Start the engine and warm it up for about 10 minutes at 3000 rpm idle. If the fan starts running, it indicates the coolant has reached normal temperature. Then tighten the filler cap and install the radiator cap.

How to Take the Driving Test (Subject 2) During Heavy Rain?

Turn on the wipers in time and control the speed. Relevant instructions are as follows: 1. Maintain distance: When driving in heavy rain, pay more attention to keeping a safe distance than usual. Visibility is already poor in rainy conditions, and the road surface is prone to slipping. Remember not to slam on the brakes, but to use light and intermittent braking. This not only controls the speed but also gives the following vehicle enough braking preparation time under poor visibility. 2. Turn on the wipers: Do not close the windows too tightly, as the interior can easily fog up, obstructing visibility and affecting judgment accuracy. Turn on the wipers promptly when it rains, and adjust the wiper speed according to the intensity of the rain to maintain clear visibility.

Are Buick Cars Fuel-Consuming?

Buick cars have a fuel consumption of 6.87L per 100 kilometers. The following are related introductions about fuel consumption: 1. Vehicle-related reasons: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once it is damaged, it will cause an imbalance in the engine's fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the vehicle will emit darker exhaust from the tailpipe during driving. 2. Long-term non-replacement of the "three filters": During the use of the vehicle, the three filters (oil filter, air filter, and fuel filter) must be replaced regularly. If they are not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.
