Automotive retreaded tires, also known as remolded or reconditioned tires, are used tires that have undergone a process to replace the worn-out tread with a new layer of rubber. This process involves carefully removing the old tread from the tire casing, inspecting the casing for any damage or defects, and then applying a fresh layer of tread using specialized machinery.

An automotive camless engine is defined as an engine configuration wherein the poppet valves are operated using pneumatic, electrohydraulic, or electromagnetic actuator systems instead of conventional cams. The intake or exhaust valves are operated using this camless arrangement of the camshaft, which incorporates the use of springs or other means. This type of engine configuration has been recently developed by engine designers and developers for achieving optimum performance and fuel efficiency in addition to reduced carbon emissions.
