According to the characteristics of run-flat tires, after a puncture, they can still maintain a speed of 80km/h, allowing you to drive for about an hour and cover a distance of nearly 80 kilometers. Here is some information about run-flat tires: Advantages of run-flat tires: In the event of a tire leak, even if the air pressure inside the tire is completely lost, you can continue driving at a speed of 80 km/h without having to replace the tire immediately. Disadvantages of run-flat tires: In terms of tire quality, due to the thicker sidewalls, run-flat tires of the same specifications are heavier than ordinary tires, which to some extent can reduce the performance of the car.

Run-flat tires, also known as zero-pressure tires, are designed to allow you to continue driving after a puncture without immediately stopping, preventing you from being stranded on the road. The standard recommendation is to drive about 50 to 80 kilometers, provided your speed does not exceed 80 km/h. From an automotive repair perspective, I know this depends on the tire brand and vehicle model—some luxury models might last longer, but don’t push your luck by driving too far. The key factor is that after losing tire pressure, the reinforced inner layer supports the weight, as long as the wheel rim isn’t severely damaged. However, once a tire blows out, avoid continuing on highways—keeping your speed between 50 to 60 km/h is safer until you reach the next service station or repair shop. Driving long distances on a flat will completely ruin the tire and may even damage the suspension, which isn’t worth the risk. Remember, this isn’t a permanent solution; timely action is crucial. Checking tire pressure during annual maintenance can reduce the chances of a blowout.

Can You Do Exercises in the Car?

Instead of complaining and feeling frustrated during traffic jams, why not try some in-car exercises? Not only can they help alleviate anxiety, but they can also easily relieve neck and back fatigue and promote spinal health. Here are some specific exercises you can do: Stretch Your Back: Sit on the front third of the seat, leaning forward as much as possible. Hold the seatback with both hands, arch your upper body backward, pushing your chest forward and tilting your head upward at a 45-degree angle. Twist Your Waist: Sit on the front third of the seat, keeping your body upright and shoulders relaxed. Place your right hand on the steering wheel and wrap your left arm around the seatback. Use your waist to twist your body to the left, then switch directions and repeat. Wrist and Palm Press: Extend your right hand with the palm facing forward, and press the fingers of your right hand with the palm of your left hand. Apply inward pressure with your left hand while resisting with your right hand for 5–10 seconds. Switch hands and repeat the same motion, pressing the fingers of your left hand with your right hand.

Reasons for a Forklift Having Fuel and Electricity but Failing to Start

It might be due to the forklift's battery being dead or malfunctioning. Here are the detailed explanations: Forklift battery has power: but fails to start, and the starter motor does not respond when turning the key. Check if the starter has any faults, poor contact in the wiring or battery connections, or insufficient power supply. Inspect whether the fuse is functioning properly and if the key switch is in good condition. If the above points are normal, measure and check if the battery voltage is above 12.5V. If the battery is aged, replace it with a new one. Having power and fuel: First, open the engine hood, pull out the central high-voltage wire of the distributor, place it 6-7 millimeters away from the cylinder block, turn on the ignition switch, and then crank the engine to observe the spark condition of the high-voltage wire. Then, remove all spark plugs to check for any damage. If it's a diesel vehicle, inspect whether the high-pressure fuel pump is injecting fuel normally and if the fuel injector's atomization is functioning properly.

How long is the Hyundai Elantra body?

The new Beijing Hyundai Elantra has a body length of 4680mm. The specific introduction of the Hyundai Elantra is as follows: 1. The new car has undergone minor adjustments in exterior details, such as the LED daytime running lights changing from the previous C-shape to a more complex style, while the rear retains its original design. The body dimensions remain unchanged, with a length, width, and height of 4680/1800/1450mm, and the wheelbase is still 2700mm; 2. In terms of configuration, the car is equipped with an electric sunroof and a rearview camera, while the high-end models also feature front parking sensors. There are three styles of wheels, ranging in size from 16 inches to 17 inches, with tire specifications of 205/55-R16 and 225/45-R17; 3. In terms of power, the new car uses a 1.4T engine with a maximum power of 95.6kW (130 horsepower) and a maximum power of 84.5KW (115 horsepower).

Can the in-car recordings of the BYD Han be replayed?

The in-car recordings of the BYD Han are generally only stored temporarily for a few days, and the temporarily stored recordings can be replayed. Below is an introduction to car dash cams: 1. Definition: A dash cam is a device that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence for traffic accidents. For those who enjoy road trips, it can also be used to document the journey through challenging terrains. While driving, it continuously records videos, capturing the time, speed, and location, functioning much like a "black box." It can also be used at home as a DV to record life's joyful moments or serve as a home surveillance device. 2. Function: It safeguards the legitimate rights and interests of drivers. In case of a collision with pedestrians crossing the road or cyclists and motorcyclists, drivers might face extortion. With a dash cam, drivers can provide valid evidence for themselves. By replaying the recorded footage, the responsibility for an accident becomes clear, enabling traffic police to handle the incident quickly and accurately. This allows for a swift clearance of the scene to restore traffic flow while preserving crucial evidence from the incident, thereby creating a safe and smooth traffic environment.

What is the normal tire pressure for run-flat tires?

Standard tires have a recommended pressure of 240kpa-250kpa, while reinforced tires should be inflated to 280kpa-290kpa. Note that cold tires and hot tires have different pressures, with hot tires being about 20kpa higher than cold tires. The manufacturer's recommended value refers to cold tire pressure, which should be around 230kpa-250kpa when the vehicle is cold. However, always refer to the specific pressure marked for each vehicle. The reasons are as follows: 1. Tire pressure is a crucial factor affecting tire lifespan and fuel efficiency. Improper tire pressure selection can cause power cycling, increasing tire wear and reducing service life. Considering its impact on vehicle performance, selecting the appropriate tire pressure is essential for extending tire life and improving economy. 2. Tire pressure is significantly affected by seasonal factors. In summer, high temperatures cause tires to heat up during driving. Excessive pressure may lead to blowouts, so slightly lower pressure is recommended. In winter, tire pressure should be slightly higher than in summer due to thermal contraction and expansion. A winter tire pressure between 250kpa-280kpa is generally appropriate.

What to Do When Shock Absorber Dust Cover Makes Noise in Winter?

If the shock absorber dust cover is making noise, it is necessary to check whether the shock absorber is leaking oil or if there is an issue with the pressure bearing on the shock absorber upper cover. Timely replacement can resolve the problem. The specific methods are as follows: 1. First, listen directly. Under low-speed driving conditions, if the tire passes over a raised area, there will be slight vibrations accompanied by a hollow sound. The sound appears dull, and at this point, you can use experience to determine which suspension is producing the noise. Then, further inspect for any damage. If there is no damage, do not make any adjustments and take it to a repair shop for inspection. 2. Next, observe. Check if the shock absorber is leaking oil. Without rain or car washing, look for oil on the shock absorber shell or dust cover—this is very obvious and can be seen directly. 3. Finally, use your hand to press. Press down on the upper part of the suspension, such as the front and rear fenders. If there is a fault, the shock absorber will feel unusually stiff, which is usually caused by long-term oil leakage and also needs to be addressed.
