Multi-diameter tire and wheel assembly for improved vehicle mileage with passive transfer between tire diameters

摘要

The invention is a three tire and rim wheel assembly called the TTAssembly. The assembly consists of a large diameter center wheel with two identical smaller diameter wheels on the inboard and outboard sides respectively. The TTAssembly replaces the standard rim/tire assemblies on a vehicle, one for each hub. This maximizes gas mileage and the safety requirements of the vehicle. It also reduces maintenance costs and eliminates the need for a spare tire.
