In a previous post I mentioned there's no steering lock on the 981. Been meaning to mention the discrepancy between the published 19" winter tire pressure being 32 psi (all 4*) versus what the actual TPM shows for on spec pressure, that being 30 psi. This yields 0 psi on the over/under pressure indicator. This discrepancy might have to do with the early printed publication of brochures, owners' manuals, etc, versus final software settings in production. Another possibility is the US models' settings are different from ROW, and again,not reflected in the literature.
* Same all around strikes me as being a bit odd, but I suppose it has to do with Porsche's extensive real-world testing. If anything, I keep the front winters at 30, and the rears at whatever yields 32 and +1. In other words, favoring slightly higher pressure at the rear.
