Greetings from a soggy Adelaide, South Australia to you guys and girls?
This is my first post and I joined last week having bought my first new car in
43 years would you believe! It's an i30 white hatch auto 1.8 Trophy and I'm in
love with it. My neighbours are used to seeing me washing my car after a soaking rain
which kept my previous Mazda 323 in very good condition for 14 years.

Do i have any minor complaints you might ask? Well yes the drive home from the dealer
on tyres with 40psi pressures was not a good start, and badly aimed headlights since rectified by the technical guys at the Royal Automobile Association with their equipment.
And why when driving on slightly uneven bitumen do I hear an occasional rattle from the
passenger side similar to the wing mirror being loose in its mounting. Or is it generated
by the vent louvres. I gave my co-driver the job of locating the source and she said the noise is coming from my side.!!! As my hearing is so acute I hear of a crack in a table tennis ball long before my fellow players. I'm still convinced the rattle is from the passenger side. It wouldn't be the first time I've been wrong however.
Just as well I have you guys to prove to solve the riddle for me.

You might wonder why I chose 'lingua franca' as my sign-in. My Pocket Oxford explains it thus, "language used in common by speakers with different native languages"
Judging by the world wide membership in our club it seems very appropriate.

Now I'm off to today's foggy Adelaide Hills for lunch (and to see how good the fog lamps are).

Cheers Will

Really

That's scientifically impossible, unless your fellow players are a long way away.

We can't help with your rattle without being in the car, however, there have been reports of a rattle emanating from the central rear view mirror on the windscreen and very difficult to locate. Are you sure sunglasses are not rattling in the compartment in the roof.

Sometimes good hearing is a disadvantage. Most of us oldies suffer from tinnitus.

Welcome Will, great first post.. I split this off so not lost in Wingfoot's intro..

Could be the glovebox maybe ... (very hard to diagnose by remote control)

Do some searches on here for rattles and see if that gives you any tips. Series 1 (FD) and Series 2 (GD) are fairly different...

My Camry had over 40 PSI when I collected it (slack aren't they)

40psi is an absolute minimum for me.

Just Rick · **Reply #4: July 24, 2014, 12:36:53**

Yes 40PSI here too,highly recommended for any front wheel drive car,I will runn the rears a few pounds lighter.

I can hear a crack in a ping pong ball as well,but bugger it's hard to hear the Missus,when she's talking

VaerO · **Reply #5: July 24, 2014, 13:28:20**

Why have the PSI so high?

Surferdude · **Reply #6: July 25, 2014, 04:47:08**

I suggest 36 -38 but 40 is OK.
The increase in pressure will give the car much more positive steering response. It will also reduce outside shoulder wear which is especially evident on front wheel drive cars as they tend to plough a bit (understeer) when entering and negotiating roundabouts, distorting the left front (in RHD cars) so that the outer shoulder carries most of the weight of the car throughout the turn.
But once you get above 40, you run the risk of centre rib wear if you do a lot of high speed, highway driving due to the effects of centrifugal force.

The Gonz · **Reply #7: July 25, 2014, 07:02:13**

As your tyres wear, regularly compare centre to shoulders for even wear, nice and square. If shoulders are rounding and lowering more than the centre, add pressure. If the centre is wearing more, reduce pressure. That's pretty much all the science you need for your particular driving style. For mine, 40psi has been perfect.

Welcome to the club Will

The best pressure for your tyres is what is written on the sidewalls of the tyre.

I also had a slight rattling issue which I'd been searching 2 months for - it was a pen in the glovebox

Doggie 1 · **Reply #11: July 29, 2014, 13:06:35**

Ah, the old pen15.

Welcome to the club Will The best pressure for your tyres is what is written on the sidewalls of the tyre.

Just to clarify that. There's only one pressure figure on the side of the tyre and it is the maximum that tyre is rated for - which is well above what is recommended for our cars.
For instance on my 195/65R15 tyres the pressure figure is 51 psi. At 51 psi, that tyre is rated to carry a maximum of 615 kg. Obviously tyres fit more than one car and in general, manufacturers use a tyre with some considerable safety reserve built in.
As you put less (or more) pressure in a tyre, its load carrying capacity varies accordingly.
There is a whole range of charts available in the relevant industry manuals.

I think what Craig was referring to was the tyre placards attached to every car. These list what sizes of tyres and rims are acceptable on any given car plus recommended (by the vehicle manufacturer) tyre pressures.
