Distinguishing run-flat tires can be done by: 1. Checking the sidewall of the tire for special symbols following the specifications, which are absent in regular tires; 2. Placing the tire flat on the ground and standing on it—run-flat tires have hard sidewalls, while regular tires feel soft when pressed by hand. Run-flat tires are primarily designed to prevent loss of vehicle control in the event of sudden tire pressure loss. They consist of the outer tire, standard inner tube, spare inner tube, steel rim, gas generator, pressure sensor, and control unit. Characteristics of run-flat tires include: 1. They possess support and toughness, allowing the rim and tire to combine and support the vehicle safely during sudden air loss or a blowout; 2. After a blowout, run-flat tires do not immediately lose all air, enabling the driver to continue driving for a certain distance with reduced pressure; 3. The reinforced sidewalls of run-flat tires enhance durability and usability.

What is the maintenance interval for the Yamaha Xunying?

The maintenance interval for the Yamaha Xunying is generally every 1,000 kilometers. Maintenance items: Replace the three filters and engine oil, including the diesel filter, oil filter, and air filter, as well as the engine oil.

The maintenance instructions in the manual are the most accurate, and there is no need to adopt other methods. Appearance introduction: The front of the bike is stylish, and the rear is solid. The headlights use LED light sources for the first time, and the position lights can function as daytime running lights, complementing the overall crescent-shaped design. The high-end model features chrome-plated mirrors. In position light mode, the taillights achieve a light strip effect, and the brake lights also use LED light sources.
