Does the 2021 Mercedes-Benz E-300 come with run-flat tires?
1 Answers
2021 Mercedes-Benz E-300 does not come with run-flat tires. Below is a brief introduction to run-flat tires: 1. Material: The main material of tires is rubber. The most widely used types include natural rubber, polybutadiene rubber, styrene-butadiene rubber, and butyl rubber. Modern tubeless tires are mostly radial tires. Early radial tires were reinforced with steel wires. With advancements in chemical technology, steel wire radials have gradually been replaced by synthetic fibers like Kevlar, which are lighter and have higher specific strength. Run-flat tires are manufactured by adding thickened rubber to cover the sidewalls of the wheels on this basis. 2. Function: If a tire loses pressure due to a puncture, the sidewalls can still support the vehicle's weight. Even in the event of a puncture, the tire will not deform severely, ensuring stable driving for the Mercedes-Benz E-Class.
