More wear on the inside of both the front and rear tires is normal. This is due to the stock alignment which adds a small amount of negative camber (top of the wheel is tilted inward). This improves corner handling at the expense of slightly accelerated wear on the insides of the tires.

The shop can set the camber to around zero to try and even out the tire wear across the tire but this will come at the expense of cornering performance.
