If the tyres are totally flat do not try and "sneak" the car anywhere or you will ruin the sidewalls of your new tyres and make

them unserviceable.

Are the rims aftermarket ( ie mags) or are they the original rims? If they are aftermarket/secondhand rims then this may

explain your tyre iron problem.

It is more probable that the tyres have leaked between the bead and the rim. This will often occur if an inexperienced or

inattentive fitter does not  initially over pressurize the tyres when fitting to ensure that the bead and rim are correctly

contacted.

It can also occur if the rims had some rust scale around the bead line and it was not cleaned, or not correctly cleaned.
