You can get inflatable car "jacks" that are used to lift a vehicle on soft or uneven ground. They are just inflatable bags. My recollection is that they are inflated at low pressure using the exhaust of a motor vehicle runing at idle.
They would surely be cheaper than a set of tyres from a Rolls Royce, and less likely to do damage.
They would also be useful for helping to recover a plank that overan a runway into soft ground too.
No, I am not on commision (not yet anyway)
