Walter assesses how to accurately predict tire wear – and concludes that a simpler, universally recognized technique is needed to replace current lab test machines

Vehicle fuel energy is consumed not only in linear motion, but also in overcoming the inertia of rotating components. These spinning components create a dynamic response, known as an ‘effective mass’, that seemingly increases the overall bulk of an accelerating vehicle. This virtual mass, added to vehicle weight as an equivalent non-rotating constituent, adversely affects the acceleration performance and fuel economy of all road cars
