I am sorry if what I am about to ask is a repeat but this thread is getting soooo long...but good.
I am about to acquire a Q7 3.0 tdi. The vehicle was sat in its splendor on the forecourt on 4 slicks, which prompted me to do some research on the tyre (tire) wear problems and the correct spelling of tyre (tire) but thats for another day.
My questions revolve around the way the vehicle suspension is aligned. This car goes up and down on its air suspension about 60mm. This must affect the camber setting. If you check alignment high (which I believe is the Audi recommendation, sorry not got the vehicle yet so not sure what this corresponds to on the MMI) at speed it lowers and probably increases its camber significantly toe-in probably remains unchanged. I am sure it is a camber issue as most tires wear dead smooth on outside edge. I intend to ask my alignment garage if they can tell me how adjusting height is affecting the alignment. Dynamic position seems to be closest to the high speed height but I think this may still be 25mm higher. Can we adjust camber on this vehicle? and what height should we align at?
Thanks for a great thread, I fully intend to up my pressures above the 40 psi mark, My existing car A8 4.2Q 2002 on 20" runs on 44 psi all round - I doubt the Q7 will hurt that much over the pot-holes in the UK!
For those interested the UK licence plate start with two letters which sort of designate the area, then two numbers the first can be a 0 - march or 5 - september followed by the year so MA57 ABC would be Manchester, September 2007, ABC are random letters. in 2010 it all went wrong so we are now at MA60ABC as MA50ABC has already been used. Any guesses as to what is next, probably MA11ABC.

Reason: adding information about UK 'plate' notation
