Looking for a reliable off-set tire pressure gauge.
This.If I were running IRL, NHRA or NASCAR where 1/10th of a pound could effect handling/traction I'd get the best calibrated digital gauge money could buy. The DL is a much different animal and any $0.99 pencil gauge available at the counter of any auto parts store is more than accurate enough.
Like oil and chain lube, we overthink this subject. It is true, however, that a pencil gauge will wear out over time. Moving parts.
