I’m running a base 2018 Carrera on 19” rims and have got very confused. The door plate has 30/36 with a pic of a speedo going quite high, and below that 29/32. The manual has 30/36 part load and 34/43 full on one page and 29/31 part, 30/37 full on another page following a ref to ‘comfort setting’. So which is right for most driving?

Do you spend most of your time with the car fully loaded? If not, that narrows it down to the two part-load settings.

One is comfort, the other is normal. The tyres are not rated for high speed at the lower pressure comfort settings.

I personally use the comfort setting, and I believe the car will issue a warning if you try and drive above something like 149mph with the comfort settings selected.

(Bear in mind this is on my 991.1)
