Wheel Alignment Settings

[Skier1]

Well I have read quite a number of different specs on Wheel alignments but I was wondering who has had one done recently and what specs did you use . I have a 2006 E53 Sports non air suspension running on 20" rims .It is a everyday runaround vehicle so I am not concerned setting the suspension up to make it handle better but I am after longer tyre life .I am currently getting the usual wearing of the inners on the 4 tyres.This wear is the same on all 4 corners so it is currently set up " pretty even"
I have booked it in to get a alignment but would like to supply my own specs to get the max tyre life, the shop said if it is possible they will set the suspension how I want it but I need the specs . Can anyone assist. Thanks
