I just use a valve core removal tool and take the valve out, when theres a noticeable bulge in the tyre, i put it back in. Just make sure that you have a spare valve or two incase you drop, loose, or bust one.
15 seconds per tyre max.
The frustrating part is slow compressors pumping them back up again
, which is why i bought two 76 litre per minute compressors.
EZE.
