Front tires outter edges destroyed on 2 sets - driver's side is noticeably worse.

I have a 2011 x5m that I got 6 months ago with 2 sets of wheels - 19 inch 255 Continental RF winters on 298M and 20 inch staggerred 275/315 Bridgestone summers on 299M.

Winters front outter edges shown bad wear, but they were already rathsr used. But the Summers were very good all around and when I did the swap from winters 2 weeks ago to drive to Florida from Toronto (~5k kms both ways) they looked amazing. On the way back I noticed that outter edges on fronts, especially on the driver's side are disappearing fast. So in 2 wks and 5k kms my fronts are rather gone. The plan is to visit the alignment shop again and then probably buy the same type tires and do the alignment again.

When I bought it, the lower control arms and front springs were changed so alignment was done then and redone 2k kms after at Midas after i touched the curb.
