Should the Tire Valve Stem Be Replaced?

You can choose different valve stems when replacing tires, and it is not necessary to replace them separately. Here are specific details about valve stems: 1. Rubber Valve Stems: Due to the unavoidable aging issue of rubber material, the valve stem body will gradually crack, deform, and lose elasticity. When the vehicle is in motion, the rubber valve stem will also swing back and forth with centrifugal force, causing deformation, which further accelerates the aging of the rubber. Generally, the lifespan of a rubber valve stem is 3-4 years, similar to that of a tire. Therefore, it is advisable to replace the rubber valve stem when replacing the tire. 2. Metal Valve Stems: To avoid the aging problem of rubber valve stems, metal valve stems have gradually appeared on the market, with steel valve stems being one of them. Due to the change in material, the price of steel valve stems is significantly higher than that of rubber valve stems. The lifespan of steel valve stems is two to three times that of rubber valve stems, mainly because the metal material is less prone to oxidation. Additionally, metal valve stems offer superior airtightness.

Is there a speed limit for motorcycles?

Motorcycles have speed limits. The maximum speed for motorcycles must not exceed 80 km/h, and they must travel in the rightmost lane. Relevant information is as follows: 1. Note: There are clear speed regulations on highways. The maximum speed for cars is 120 km/h, but motorcycles on highways cannot exceed 80 km/h, with a minimum speed not less than 60 km/h. This can indeed be challenging for riders who are not skilled at controlling their speed. Within this speed range, there is only a fluctuation of 20 km/h, making it easy to exceed the speed limit or fall below the minimum speed if not careful. 2. Motorcycle: Hello Motor is the largest comprehensive motorcycle service platform in China. It provides over ten million users with services such as online vehicle viewing, motorcycle pricing, actual transaction prices for new motorcycles, local lowest price offers for new motorcycles, second-hand motorcycle trading, official motorcycle equipment stores, motorcycle reviews, motorcycle driving tests, motorcycle community discussions, comprehensive electric motorcycle information, riding track records, sales and maintenance specialty stores, motorcycle insurance, and more.

Can You Release the Clutch While Braking?

It is not advisable to do so frequently, as doing it often or for extended periods can lead to premature wear of the clutch plate, thereby shortening its lifespan. The clutch is a common component in mechanical transmissions, allowing the transmission system to be engaged or disengaged at any time. Its basic requirements include: smooth engagement, quick and thorough disengagement; ease of adjustment and repair; compact size; lightweight; good wear resistance and sufficient heat dissipation capacity; and easy and effortless operation. Below are the functions of the braking system: 1. Service Brake: During driving, the service brake (foot brake) is commonly used to slow down the vehicle or stop it within the shortest distance; it also helps maintain stable speed when driving downhill. 2. Parking Brake: The parking brake not only keeps the car stationary but can also be used if the service brake fails. Once the vehicle is stopped, the parking brake (handbrake) should be applied to prevent the car from sliding forward or rolling backward.

What to do with ETC when replacing the front windshield?

After replacing the front windshield, the ETC needs to be reactivated at the ETC service office. ETC activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth is on". If "Tag invalid" is displayed when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. You can also directly press the button on the top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile APP (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click on device connection and wait patiently for the "Connection successful" prompt. After successful connection, upload a photo of the front of the vehicle to complete activation. How ETC works: Through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, using computer networking technology for back-end settlement processing with the bank, the vehicle can pass through highway or bridge toll stations without stopping to pay the highway or bridge toll.
