How to inlflate JCB Tyres....
Mr Dabbs you are a genius !!!
To answer your concerns... inflating a JCB tyre gracefully in less than 30 seconds is actually quite simple and does not require any deep understanding of continuum physics but only of british zoology.
You only need a politician - or second best a Shoreditch startup marketer - as these are the only two local species known to exhale more than 300 gallons of hot air per second as part of their normal physiological processes.
