Then get a bike pump. You don't need much volume, so a hand pump is
fine, but you need greater pressure than typical car inflators can
deliver.

My bike pump is a Silca track pump - probably the best bike pump you
can get. It'll easily do a car tyre (even a 7.50x16) but you wouldn't
want to wait for it, given how long it takes to shift that much air
with a narrow piston.
