Which tyres should I get for my Lexus GS?

My 2011 Lexus GS is fitted with Dunlop SP Sport 2030 245/40 R18 93Y radials. What is the best tyre to fit for a comfortable (not sporty) ride? Thank you

The smallest, deepest profile tyres size seems to be 225/50 R17. The current 18 inch tyre size for Lexus GS is 235/45 R18, which will be a little more comfortable on the existing wheels.
