If this is something that requires any real level or thought or consternation, one needs more hobbies or activities!
And define “same”. Now that I got a few vehicles with TPMS, it seems it is pretty close to gauge readings. And of the random gauges I have floating around, all appear to be pretty close. Newver gsve any thought to a couple psi difference.
Unless maybe drag racing or circle tracking.
And if being “accurate” or the “same” super important, do you take into account lateral weight bias per axle. Weight of fuel and passengers can make a big difference dontcha know!
