What’s wrong with the measurement protocol vs. tire wear?

Take a look at the attachments and tell me if the wear is really like this with the azuf print on the protocol. The measurement is from May 2011. After the measurement I only changed the coupling rods and had no curb remplers or the like. Chassis is Kayaba Exel G + Eibach 45/30. QL, support joints are play-free and SSK are new MEYLE HD. Shortly before the measurement incl. chassis installed. Air pressure was always between 2.2 and 2.3 bar. the front wheels. So purely theoretically too much negative crash, a little bit more. As a comparison a picture like the tires on the outside look like.http://imageshack.us/photo/my-images/267/picture008b.jpg/http://imageshack.us/photo/my-images/33/picture002ac.jpg/http://imageshack.us/photo/my-images/401/image007wo.jpg/ I have to measure again before I yodel down the almost new winter tires or is this simply the negative side taste of a low set in the Astra? Running performance TO the Verm ssung about 710tkm, tires in total so ~25-30tkm.
