System comprising a light run-flat wheel assembly and an ESP device

摘要

The system has a rolling assembly including a wheel with rim (22), a tire and a rolling band supporting ring (42) for tire, where the ring is of low width. An electronic stability program controls dynamic behavior of a vehicle. Ratio between axial width of the ring and axial width of the band is lower than or equal to 0.30. A unit e.g. pressure sensor, detects contact between the ring and the tire.
