I was reading enRoute and came across a post about changing tires and I remembered this thread with videos with Captain Doug Morris.

How Aircraft Tires Keep the Air Canada Fleet Rolling

Groove‑treaded and nitrogen inflated jumbo tires are the unsung hero of every flight.


QUOTE:

"Unseen by passengers on board, tires are a big deal in aviation: Each of the 12 tires on the main landing gear of the Boeing 777 (Air Canada’s largest aircraft) is more than 1.3 metres across and weighs in at 120 kilograms. And every tire in the fleet has its own history, tracked in its own file and monitored closely by the maintenance team."
