VW Touran - Tyres worn inner and outer edges?

[Ray Singh]

Ive a 04 plate VW Touran. Its currently running on Pirelli P6000.
The front tyres seem to wear really quickly. They last less than 10k miles.
They wear on the inner and outer egdes. Mainly outer.

Any ideas what causes this? Is it due to worn suspension components? Or perhaps over/under inflated tyres?

I'd get the geo checked just to make sure but it does sounds like under inflation.

If they are worn on both inner and outer edges it would suggest under inflation, at some point in the life of the tyre, yes.

Thanks for confirming.

Behind the fuel filler cap are two pressures for the tyres.
One for the car loaded and one without any load.
Which one do i use? We hardly ever fully load the car, its a "kids to school wagon".

Somewhere between the 2 if it's only ever partly loaded. To be honest they would have to be fairly low for a long to cause that sort of wear

[Ray Singh]

Ive been inflating them to the lower level as suggested by the fuel filler cap.
I will try filling them in between the two marks, but i need a new set of front tyres now :-(.

How much do your kids weigh? Unlikely given the vehicle and it's kids we're dealing with but a fully loaded small car can consist of putting 4 adults in it.

Also the book pressure will be set for running at all speeds. The lower the speeds the less the center of the tread is pushed against the road. I doubt you do the school run at 70.

Basically up it a bit to somewhere between the two values.

[Ray Singh]

We are only ever using the car for school runs.
Kids weigh nothing, they are skinny and 5 and 7 years old.
The journey gets up to the dizzy heights of about 50mph max.

Make sure you get the tracking checked.

Pirelli Ditchfinder 6000, you put those on intentionally?!?

Shoulder wear is usually due to under inflation.

If you drive to a forecourt your tyres are hotter when you are measuring their pressure - so 30psi could settle to 28psi or whatever when cold again.

Also, don't underestimate how wrong some of the forecourt tyre pressure readers are.

On the driveway with one of these is the answer:

Agree. The ones on my Jag are awful. Problem is that the bloody things never wear out.

[HellDiver]

It's probably a side effect of the lack of grip on the P6000. Turn wheel, fk all happens. Turn further and get a bit of grip from the wheeltrims and turn the corner. Consequence is worn Ditchfinders.

As above, please do not contemplate refitting P6000's.

P6000 normally wear very slowly because they offer zero grip in anything but perfect conditions.

[HellDiver]

Cue 300hp/ton saying he thinks the Ditchfinders are the best tyre in the world EVAR!!!111one11!eleventy

[Thudd]

Aren't the recommended pressures only correct for the OEM spec tyres?

I'm guessing the Pirellis need a little more.

I had some of these on the rears on my old focus (when I first bought it). They were so noisy and made the back of the car step out so badly that I thought there was something wrong with the rear suspension. Has the whole lot checked and there was nothing wrong. The mechanic pointed out that 'you might want to change them st things you have wrapped round the wheels though'.

He was dead right
