Low Emission Vehicles that are hybrid and electric cars may benefit from specially designed tires that are optimized for driving conditions typical for such vehicles. It is possible that in the future Low Emission Vehicles, especially passenger cars, will substitute conventional vehicles in all applications, however for the time being they are mostly used in urban and suburban areas. Urban traffic has a rather low demand for grip performance of tires due to relatively low speeds. At the same time it imposes high demands for low noise emission of tires, as traffic noise is one of the most difficult environmental problem in towns. For electric vehicles there is also a very high need to ascertain necessary vehicle's range of operation by lowering the rolling resistance of tires as much as possible. The paper discusses selected aspects of hybrid and electric tires’ use and presents results of noise measurements performed for tires that are specially designed for LEV's or that are commonly used in such vehicles. The measurements were performed both at the laboratory using roadwheel facilities with drums covered by replica road surfaces and on the road by the Close Proximity Method. As supplementary information, to prove that there is no conflict between low noise and low rolling resistance tires, rolling resistance of tested tires is presented.
