Kreativ, let us know how your tires are for you. I'm looking for a new set of tires (got the OEM EL400's now) and I'm split between the MXV4's and the MXM's. Btw, the serenities are several pounds heavier than the Michelins per tire so there will be some impact on performance. I want a bit more grip then the MXV4's which my wife has on her ES350 and they are super quiet and smooth, but I noticed they aren't as good as I thought in the rain, my Goodyear Triple Tread's gripped much better, but noisy and a bit harsh on the ride.

 

I have installed 4 Michelin Primacy MXV4 V Rated and quite happy with the ride and the fuel efficiency. I got it installed and balanced in a private garage in Mississauga, Ontario as the dealer was quoting almost 50% more for the same tires. The wheel alignment was done at the dealership.
