TPS not very accurate?

[Schwerin]

I've noticed my TPS are a good 3psi off vs a good tire Guage. Is this the same for you guys? I have all my tires at 35-36 but the dash shows 32-33psi.

Set mine all to 33 the day I brought it home. The dash reads 33 for 3 of them, and 32 or 33 for the 4th. Guess I got that one closer to 32.5. Either way, it seems ok to me.

Mine reads high by 2-3 psi

I think it varies. I kept my tires at the required pressure according to the tpms gauge and the first set wore out on the outer edges first - so probably a few psi low. Now I still go by the tpms but add 3 psi.

TMPS Sensors are there to warn in case the pressure drops significantly, not to show precise numbers.

Get a good gauge for precise numbers.

Mine are dead on... guess I got lucky

Mine seem accurate compared to my guage and compressor

two of mine are right on and two of mine are off by 1 psi according to two digital gauges I have, that both match each other.

Mine match my hand gauge.

Mine all read within 1 psi of my dial gauge.

this is probably the reason the manual specifically states not to use the TMPS as a tire guage. RTFM

Mine all read same as two different tire gauges I've check them against.

Same. Mine read +3psi. Bought a good quality gauge.
