How to fit a hard to fit tyre without using levers

Disagree XH - putting a schwalbe marathon plus onto a mavic ksyrium elite rim definitely requires the use of levers. You cant use the technique on this video either as the rim doesnt have a 'well' in the centre - careful use of levers only for the last section

You're definitely doing it wrong. Why on earth would you put heavy tyres like this on a wheel like this?
