New to 16" tyres, The door sticker states "30psi", Bob Jane "34psi"
I have 32psi in them and they still look "flat".
They are on a AU Series 111 Fairmont Wagon, with 5.0L V8.
Cheers

What does the tyre say?

A little more is better than a little less!

Hey casrms,
I had the same dilemma. What I have found though is that car makers will generally recommend a pressure in the lower range of acceptable because that favours ride comfort with a small detriment to handling. I got new tyres (215/60/16) a couple of months after buying my AUII and after 5000km on the new ones, I thought the rears were starting to show an under-inflated wear pattern. Tyres had been inflated to 30psi initially. Since then I've run them on 35, but the change to ride comfort was so small as to be insignificant. The tyres have been rotated since, and the ones that were on the front are not showing the under-inflated wear pattern since they've been on the back and had 35 in them. So I'd say definitely go higher. 30 is the same as recommended for the sedan, I'm surprised the wagon isn't higher because of the weight difference. Plus you've got the V8 which means a bit more weight over the front axle. So all the more reason for higher pressure.

On my Au with 15s I always run 40psi front and back.Stops sidewall distortion when cornering and makes the tyre wear flat and even.Should be the same for 16s,don't be afraid to try different pressures till you find one you are happy with.If in doubt ask the tyre manufacturer the maximum allowable pressure and don't exceed it.

Thanks Guys. I am going to run the tyres on 34psi,as Bob Janes suggested. 40 sounds a bit high. But if it works for you, great !
