More on tyre wear.......

In the ongoing search for the perfect tyre pressures (32psi rear and 28 front is looking good) I have checked the wear on the front of my C4S today and found the following wear tendancy.
The tyres are worn symetrically- the wear is from the inside of the tyre evening out across the breadth of the tyre, ie it is near the wear indicator on the inner part of the tread and the wear reduces across the face of the tyre.
Is this characteristic of correct tyre wear on the front of a 911 or is the tracking/geomerty questionable......?
I have it in my mind that it is probably as it should be, does anyone want to rain on my parade?
 
when i picked my car up in august, the dealer had on the hand over book that they reccomend 32 rear, 28 front as they have found that these are the best for optimum performance,
i have over the few months i have had the car tried various different pressures, the ones that porsche reccomend 44, 36 made the car feel very unsettled, tried some other variants, but finally reverted back to what the dealer had reccomended,
want to try a couple of track days this year to get to grips with what the car can actually do[8D]
and i feel that 32,28 will be spot on for the track,
but seeing as i have only been in porsche ownership for a few months, i would love to know what porsche experts think?
 
Having tried at least 6 different makes/models of tyres over the last few years, one point that people often miss is that there is no one "correct" pressure that applies to all tyres. IME, Michelin PS2's & Toyo R888's like to have a bit more pressure than Pirelli Corsa's. Pilot Sport Cup's like the lowest pressure of all. I favour a bit more pressure than 28/32 but if that works for you, fine. The OP's wear characteristics sound perfectly normal for road usage.

28F 32R is probably a bit low for trackdays - I would aim for 30F 34R for a normal road tyre, measured hot. It's all about feel though, so go with what works for you.
