It's the best when the nozzle is around 6 or 7 o'clock position so that you can firmly press the guage straight down which means you have to crane your head a little bit for reading. Always remember the most important thing for you is to be able to press down straight & hard onto the tire's nozzle.Package Included 1 x AstroAI Tire Gauge
