How can I improve the ride quality of my Lexus IS250?

I have purchased a secondhand Lexus IS250. It’s very nice, except the ride is very rough. It has alloy wheels fitted with 255/40 ZR18 99Y tyres. How can I improve the ride?

The problem is the wheels and tyre size. You can go down to 17-inch wheels with deeper profile tyres for this model and, for the new IS, Lexus is offering 16-inch wheels with even deeper profile tyres. These may fit the old model, but I am not certain that they will.
