Geometry Settings?

Seems like I'm asking a lot of questions here I know, but new to the ownership and just trying to find out a bit more from you folks with more experience of the KN than me....so bear with me please.


I read somewhere that the KN is prone to knocking out the outside edges of front tyres in 6K miles if the geometry is not set correctly making them illegal, but the rest of the tyre is fine, is this a common issue? I know in my impreza that geometry is a vital issue for good handling and used to have it set specifically, as the factory setting tollerence was + or- far too much. Does anyone know what the settings should be so I can have it checked by a specialist?

Thanks again.
 
Hi
Just completed 12k and the edges of the fronts are gone, but this is because it is a big, heavy beast and they take a pasting on tight corners, parking etc. I thought this was a tracking issue with my last Cayenne, had it checked at considerable expense and found it was spot on.

The rears are still fine for a good few thou but PCGB recommend all four be replaced at once due to differences in circumference between new and worn tyres affecting the diffs. Whether this is strictly true or not I don't know.
 
Thanks for that, think I'll just keep an eye on them and rotate back to front once the edges show signs of wearing in that case. It should help with even wear all round.

..and yes I always used to change all 4 together on the Impreza for that very reason of not winding up the diffs with rears going round quicker than fronts or visa versa.
 
[:D] I've heard these rumours as well, had a similar experience with my previous Jeep, with the first set of tyres the front near side inner edge went at under 10k, however this never occurred again after I complained about the tracking which was checked ...... the dealer claimed it didn't need adjusting and that all 4X4's did this to their tyres (Yeh right) Generally managed about 30k a set. My Cayenne has managed almost 29k on it's first set of tyres, which I didn't think was too bad, especially for Pirelli Rosso's . When they finally needed doing it was the centre that was shot. There would appear to be a big difference depending on a whole range of factors, tyres, set up, driving conditions (mostly town / motorway) and driving style. Personal experience certainly doesn't suggest that a Cayenne eats it's boots.

 
Nice to hear 29K on a set, think I'll get a complete check up just in case. I'm generally not that hard on tyres so hopefully should be OK, in saying that I'll be happy with 20k on a set as I tend to change them before the tread wear blocks show.
