How to Replace a Tubeless Tire Valve?
2 Answers
Method for replacing a car tubeless tire valve: Insert the valve through the car wheel hub, pull it with pliers, then cut off the base of the valve, and finally pull out the valve for replacement. Advantages of tubeless tires are as follows: 1. Wear resistance. Since tubeless tires do not have an inner tube or liner, there is no friction between the car tire and internal components during high-speed driving. Moreover, the heat generated from friction between the ground and the tire can dissipate directly through the rim, enhancing the tire's wear resistance and service life. 2. Safety. When a car's tubeless tire is punctured by nails, stones, or other sharp objects, it does not rapidly deflate like a conventional tire, which could affect normal driving. Even after being punctured, a tubeless tire can maintain the car's operation for a period, significantly improving driving safety. 3. Fuel efficiency. Tubeless tires generally have strong adhesion, ensuring stable driving and reducing fuel consumption.
Replacing a tubeless tire valve stem is actually quite simple, but it's best to do it in a safe environment. First, park the car on level ground and engage the parking brake to ensure stability. You'll need to prepare a new valve stem, a wrench, and an air pump. Start by removing the tire – usually by jacking up the vehicle, loosening the nuts, and taking off the wheel. Then, pull out the old valve stem from the inside of the rim. Sometimes it's stuck pretty tight, so you'll need to pry it out slowly without damaging the rim surface. When installing the new valve stem, first check if the sealing ring is intact, align it with the hole, and gently push it in before tightening. Avoid using excessive force to prevent compromising the airtight seal. After that, remount the tire and inflate it to the standard pressure to test for leaks. Remember, while this job may seem minor, it's crucial for driving safety. If you're inexperienced or the valve stem is in a hard-to-reach position, it's best to seek help from a professional mechanic – especially when dealing with severely aged tires, as DIY attempts might cause more problems.
