Can I fit 15-inch wheels to my Lexus IS250 for a comfortable ride?

I had the good fortune to be able to take your advice and buy a Lexus IS250, petrol, automatic and I'm not disappointed. The ride is very comfortable on 17-inch wheels but would it be 'transformed' on 16-inch or even 15-inch wheels, and if so what tyres would you recommend for a quiet comfortable ride?

You can't go to 15s on this, but you can go to 16s. I reckon 205/55 R16 Toyo J48s or Michelin Primacy 3s. The new Lexus IS is offered on 16s and the IS300 hybrid gets under 100g/km on them.
