Yep w/no problems...you’ll just have some negative rake with a 0.4” shorter tire in rear.
Most common combination is 245/45/18,275/40/18...but I’m seeing the PS4’s aren’t offered in that rear size.
You could go 235/45,265/40 & both be 26.3” diameter vs. the 26.7” of the 245/275 combo.
I ran the first set I listed & many others have as well.
Hope this helps
