Maintenance for a 772 from OS.

so do they keep the jack with the spare wheel on an airliner?

Nice shots. Looks like fun. I have never played with multi bogies, but never say never

so do they keep the jack with the spare wheel on an airliner?

No, you will have a dedicated wheel change kit for each aircraft type and as a general rule it remains firmly on the ground. For example, a 737-800 main wheel comes in just short of 200kg's, the equivalent of three European or one American passenger  That is a whole load of dead weight to be carrying around. You need lifting gear for that sort of weight. I would not be too keen on loading and unloading a mainwheel each time it has to be changed. Remember, you only have one back and it has to last a lifetime.

Unless you are an Antonov-124.  I watched them change a tire on it once when it was at my airport.  The aircraft can use its onboard hydraulics to lift each wheel individually and they do carry spare tires onboard.  

I can imagine time being a more important factor then keeping a extra tire on the plane, imagine needing to fly over the tire and mis a load.

Also, most companies will not have an An124 wheel assy hanging around the store on the off chance. As for other aircraft types, it is standard practice if you have no maintenance at your destination airport to have
contracted technical help. This will include spare parts such as wheels etc. You generally can have a loaner part or you could buy. As a 737 and A320 tech I have been tasked with doing both loaner and selling parts to other companies aircraft. The rule of thumb is always to help out, because if you don't, it will come back and bite you in the rear at some point down the road.

I have never really noticed the size of the landing gear until now.
