i have a 320i lowered 2 inches with 19 inch wheels running 235/35 19's and the inside edge wear is terrible.
10000k from the first set.
the problem is when you lower the car the adjustment for camber is less.
mine is now at max adjustment and the new set of Marangonis is wearing very fast.
coupled with most tyres of this profile being softer compounds = fast wear.
you can search for a harder compound in the profile but noise increases with harder compounds too. Handling also is affected if you are a hard cornering driver.
