I have some g-force t/a kdw 225/45/zr18 91y on my car and soon need to replace 2 tires. Should I stick with these or should I look around?

I'd keep them the same at all 4 corners.

I know, but what i'm really looking for is something cheaper. I'm going to rotate the tires and probably get something cheaper after the others go out. $190 a tire is to much for me
