Thanks for the mini review. I too look forward to the Cadenza with Michelins.
I finally had enough with the Hankook tires that came on my Cadenza (17,000 Miles still had plenty of tread). They were terrible in the rain and snow. Rough and uncomfortable over bumps and imperfections in the road. I even felt that the handling was off due to the tires. I had it at the dealer 3 times to correct a shimmy, they never did. I replaced them with Michelin Primacy MXM4 tires. I cannot believe the difference. My car feels like a different car. I took it to a reputable small shop near my house to have the new tires mounted and road force balanced. They said that the dealer put weights on the inside lip of the wheel and the weights did not fit correctly. He used sticky weights on the inside of the wheel and did not place anything on the lip. I have had the car up to 85 and there is no longer a shimmy!!
I just took a trip to the beach and put about 1100 miles on the new tires and I love them.
Just for reference I have the limited model with the 19's. I am planning on putting 18's with snow tires or all seasons for this winter. I really want to keep my wheels nice!
I actually run Fuzion Tires on my after-market wheels.
They're cheap and quiet.
When I say cheap, I mean I paid $280 mounted and balanced on all 4 wheels... for 245/45R18 tires... that's a steal!
Sounds like a belt in the tread broke, take it to some one like discount tire. They have helped me before and contacted the tire manufacture about a replacement.
I'm sure there are other tire places which will do the same.
Try the Michelin Primacy MXM4 tires, or bridgestone Turanza Serenity Plus
