Let's Talk about Tire Pressure Before Driving 10,000 Miles

The dealer deflated my tires and told me my tire pressure gauge was incorrect. After some research that is possible. Tire pressure gauges can be off by a few lbs much of the time. However, for a gauge to be off by 5 lbs is very unusual and I need to find out for sure.

I will be making a 3000 mile journey in the Toyota Prius Prime 2021 and if my tire pressure gauge is bad or if my tire pressure is now low because of the dealer I have to find out! Tomorrow I will be at Clifford's Garage where we will check the pressure and hopefully make a video.
