ContiAdapt combines micro-compressors integrated into the wheel to adjust the tire pressure with a variable-width rim. The system can thus modify the size of the contact patch, which under different road conditions is a decisive factor for both safety and comfort.
Four different combinations allow perfect adaptation to wet, uneven, slippery and normal conditions. For example, a smaller contact patch combined with high tire pressure make for low rolling resistance and energy-efficient driving on smooth, dry roads. By contrast, the combination of a larger contact patch with lower tire pressure delivers ideal grip on slippery roads. The system also permits very low tire pressures of below 1 bar to be set, to help ease the vehicle out of a parking space in deep snow, for example, or traverse a dangerous stretch of black ice.
