Dave, Thanks for your response. Could you tell me please the reason why this type of wheel could not have been used on aircraft.
I am not familiar with this website so if this is a duplicate reply please excuse me. Regards, George
DaveT is absolutely correct. That hub is stamped steel (and has a rough finish which allows cracks to propagate) and thus never used on an aircraft.
It is possible the tyre was from an aircraft as electrically conductive tyres were mainly, but not exclusively, used on aircraft. They were, and still are, used also on refueling equipment and on any other equipment where eliminating or minimizing static electricity was needed.
