I have a 2.0 petrol 2018 stinger in the uk. At present my tyres are 225 45 r18. Could i get away with 225 40 r18 for front and back?

On a 2018 2.0 petrol stinger, I'm using 225 45 r18 tyres. Could I use 225 40 r18's? Would these work ok

But why? Just to make it lower?
I personally would not do it.
Btw, wouldn't you fail the MOT with out of spec tires?
