Hi guys (and gals??)

OK it snowed in the Granite City last night and as I am coming in to work this morning the dash is busy telling me that the front drivers tyre is low on air.  Had a look when I dropped off the little one at nursery and it looks fine.  Checked the pressures when I get into work and they are all at about 28psi.

I am thinking that it is just cold enough at -2C for the system to kick in, however I would have thought the pressures ar a little low for the 18 inch MS wheels :?:

The manual only states that the 17 inch version should be at 32psi, no sign of the 18 inchers.  Obviously this is the pressure the car was delivered to me at so should the 18 inch wheels be lower, the same or higher than the 17 inch??

Cheers
Brian

G-Day Brian,
I have 18" alloys on mine and I run 32psi.

Hi Brian,

I would be running 32 all around or even 34 if it doesn't effect the ride too much...It won't hurt your tyres...and shound help your economy...

[bumpkin]

Thanks all

Have gone to 32 during the cold snap we are having and will check again when it is warmer that it has not gone past 34.

Cheers
Brian

Hi All,

For info on "Checking your tires" go to http://www.carbibles.com/tire_bible_pg2.html and scroll down about two thirds of the way to see what this well regarded site has to say. You might find the section on "The Max. Pressure -10% theory." will set you thinking.

The entire article (Two long pages) is worth a read as is the entire site. Not just the geeky info but lots of common sense ans useful tips to enjoy.

What a brilliant read that was. I found the whole article fascinating (and I'm supposed to be working here   )

Thanks Bunyip that's a great site...

Enjoyable read.

I remember some of the points in the article being discussed many many years ago after an horrendous accident when tyre pressure was 1 of the contributory factors blamed for the accident.

This article explains in clear engilsh.

Thanks Bunyip

Too much info for now, its time for some shut eye, but skimmed through it and looked good. I am running 32 psi but might put it up to say 34-36psi and see how we go.

[bumpkin]

Well....................
The 10% rule would suggest that I COULD be going all the way to 39.6psi.  Guess I'll stick around the 34 mark and see how I get on :?

At an advanced driving school I was advised never to drive under 36psi ...having a curb/driveway problem if too low at the front I am at 38psi front and 35psi at the rear  (I noted that the tyre says 40psi max)

Did a 200km trip on the weekend and thought the ride was a little hard.
Decided to check the pressure on my tyres. They were running 40psi (from factory)

Let them down to 32 all round and the ride is much better.

Cam I'd be careful there mate.

If you checked the pressure right after driving 200km you will have a much different pressure to if you had checked them before the drive.

Tyre pressures increase as the tyres warm up during driving. This is normal. The figures that are supplied are when the tyres are cold.

You might want to check them again BEFORE you drive, you will probably find that they are down in the mid to high 20 psi now.

But I have to admit 40psi does seem a little high after driving. cold they might have been 35-36.

Thanks for the info Daniel.
I should have mentioned I didn't check them straight away.
