Why doesn't the Mercedes-Benz G-Class use run-flat tires?
1 Answers
Because run-flat tires produce more noise, Mercedes-Benz opts not to use them in pursuit of quietness and comfort. Below are the differences between run-flat tires and regular tires: Safety differences: Run-flat tires offer higher safety than regular tires. In cases of air leakage or sudden pressure loss, run-flat tires allow the vehicle to continue driving at 80 km/h for 80-250 kilometers, whereas regular tires, when punctured or under-inflated, can suffer irreversible damage to the tire walls due to increased temperature, potentially damaging the wheel rim in severe cases. Comfort differences: Due to their thicker sidewalls, run-flat tires are much harder than regular tires, resulting in poorer shock absorption, louder noise, and reduced comfort in the driving environment. Additionally, the poor shock absorption means that impacts on the tires are directly transmitted to components like the suspension, shortening the lifespan of the suspension system.
