While I do not have the sport model, I do have the optional 18" sport wheels on my 05ML. Primacy does not come in an 18" size but they do offer that size in the Pilot line. A smooth ride is my prime goal (and yes, had I found CL before I purchased a car I would have the std. 17" wheels!) What do you guys think I should do for the smoothest ride at this point?

 

TomLS,

The Primacy MXV4 does come in the OEM size which is 245/45/18... The Michelin Pilot Sport A/S Plus is also an excellent choice and comes in this size as well.
