Lowering the car increases camber. With the springs you have, you will not be able to dial negative camber out sufficiently to eliminate the uneven wear without an adjustable strut pearch. Even then, I'm not sure you'd be able to get enough angle dialed out of the strut. Also, the stiffer sidewall of those 19's are not giving as much as the 18 or 17's would, so there is more load on the inner sidewall than on smaller diameter wheels.

Rotating tires is always a good idea, but expensive and not always possible. Your goal is to make the outside sidewall move to the inside Some tires have an "outside" marker on the sidewall. These won't let you do the swap you need. Directionals and symmetric tires will..
