Tyre pressure

[Nelson de Leon]

question about that air pump with digital gauge sa gas station; accurate ba siya?
kasi pag nagpa karga ako sa vulcanizing shop ng 30 psi, then after a few days pa check ko sa gas station using the air pump with digital gauge laging mga 40 psi ang reading

Its fairly accurate naman for me. I also noticed yun mga tire pressure gauge sa vulcanising shops, yun stick-type ba yun, is not accurate. I dunno if its probably those generic gauges or it needs calibration or repair.
