OK I picked up my
antara last night and I was looking at all the settings and I noticed that the
TPMS was saying very different figures for my tyres, ranging from 29psi to
40psi I would like to set the correct pressure but noticed that in my manual it
says 30psi is the correct pressure for 18" tyres but in the newer manuals
it says 35PSI what PSI do you guys use/recomend in your Antara's mine is a 2008 2.0 CDTI

yes on one web site it says for mine 235/50/19 29psi and on another it says 35.when i picked mine up they where 37.7 according to the tpms?also theres alot of tolerance between a warm tyre and a cold tyre

It all depends on your "Load" as well. But go for the happy medium of 36 psi. If indoubt...Check with a tyrespecialist like ATS or Quickfit to be sure Enjoy your Antara

I currently have mine on 38 for the ECO pressure, but my manual says 35 for normal load. I wonder if you have an old copy of the manual?
You shouldn't really depend on the TPMS for the tyre pressures. Get a manual or digital pressure gauge and use that set you tyres to the correct pressure.

The TPMS is really only any good for warning you if there is a major loss of pressure while you are driving.

I have no TPM, but my manual says 35psi (from memory, either 35 or 36!) So thats what mine at set at.

I think the Eco pressures of 38 are too high and would lead to premature tyre wear

38 psi is too high, and makes the ride very harsh. If you have 19" rims, with 235 tyres, go for 35psi. (From cold). this will rise to at least 37/38psi as the tyre warms up, depending on the kind of driving you are doing at the time, and distance covered.

Yip I agree with that. I can't stand feeling every lump on he road. The extra psi does nothing for your mpg that I could see.

Looked on this site, http://www.puretyre.co.uk/tyre-information/tyre-pressures/vauxhall-tyres/ and found that there are 2 x listings, for the same size tyres, but one is for the earlier pre-facelift car, and the other for the 2011 onwards version. There is 5psi difference between the two models. Don't know why, this should be, anyone got any thoughts ?.

Antara 06 – 11 140 235/55R18 30 30

Antara 11 – 12 140 235/55R18 35 35

A guess would be that is due to some changes in suspension and steering set up. Also there was a slight weight change in the car. So that would be my guess from an engineering point of view, unless someone knows a more definative answer.
