Surely VW recommended tyre pressure is not right? (pic)

I had 4 brand new Uniroyal tyres put on my car about 8K ago, the fronts have worn bald on the outsides. I mostly travel with 2 adults and 2 children, the boot is usually full of prams and tools etc, so I have been putting the tyres to the recommended 2.5 front and 3.0 rear (bar)

But this is 36 and 43 PSI, surely it is too much?

When I do a reg check on kwik fit and some other sites, it reckons 30PSI.

Any advice?

I normally put between 30 and 35 in mine. If they are wearing on the outside its probably the tracking needs adjusting

Wearing both sides though, it could be tracking but if both sides are going, more likely to be tyre pressures.

Common causes of abnormal tyre wear:

Wear on one shoulder: suspension misalignment.
Wear on both shoulders: under-inflated tyre.
Wear along the tyre's centre: over inflation.

Sorry you said the outsides on your question. If its both then it is pressure or wheel bearings / ball joints. Check on line the pressure and also see if there is any play on the wheels. Good luck

Good point, its the outsides which are worn, I just think this is a lot of air considering what other cars take!

I do think the CV joints may be on their way out.

Do you have different wheels/tyres combo to standard? Reason I ask is my handbook gives about 5 different tyre pressures for different width/ratio/diameter tyres, also eco and comfort.

I agree. If they are balding on the outsides of the tyres (both sides of the tyre) then it is usually caused by under-inflation.

These are standard but there are 3 different wheel sizes for the car, so I don't understand how the fuel cap sticker is right, as all tyres will be different. As I say, I reckon 36 and 43 is too high, but I may be wrong, Kwikfit and other online sites say 30 in each?!

Do you have the manual? Maybe if you could provide some details about the car or wheel size, someone may have a pdf or something to help.

Sorry yes its a VW Jetta 07, tyre size is 205-55-16 - Tyre pressures are not in the manual would you believe it.

Had a quick Google and it seems you are not alone in confusion about tyre pressure on VAGs, few sites say 34 and a forum said higher due to the rear independent suspension.

I would give VW and quick call in the morning and voice your concerns, they should be able to set you right.

I inflate my 2008 ford ka's back tyres to 36psi (no passengers) so this seems about right.
