My 2 Cents
‘Tests have shown the pencil gauge
to be one of the most reliable and consistent of all gauges. They have shown to be consistently 1 to 2 psi off from very fragile laboratory- grade gauges. The 1-2 psi variation
is perfectly acceptable; some are right on.’
-- George E. Turski,
on Friday’s Rumble Seat column about maintaining proper tire pressure. It stated that pencil gauges offer only a “rough guess” of pressure.
