What I've done with my 2015 Rx350 was to go up a size in the "aspect ratio" of the tires. I went from a "60 series" to a "65" and gained 1" of total height= 1/2" more height of each sidewall- the more you have, the more "give" there is over bumps- also keep the PSI around 31. And I researched and finally picked new tires that excelled in ride comfort(according to TireRack testing) Also the bigger size has no clearance issues. I'm happy now.
