they were the most expensive here too...

As a follow-up, I ended up purchasing four new Michelin Primacy MXM4's from my local BJ's Tire Center. They cost $248 per tire plus $15 per tire for installation and balancing (includes lifetime rotation and balancing).

I noticed a quieter ride immediately and so far I'm happy with the purchase.......except for the fact that I was trying to get rid of a vibrating noise that my car makes between 55mph and 65mph by replacing my Turanzas with the Michelins. I cover that topic in my following post in case anyone here would care to chime in: https://www.clublexus.com/forums/ls4...ml#post8781566

Thanks everyone for your valuable input.

The one thing you do know is that it's speed dependent and it's setting off some kind of frequency vibration.
The first thing I would do is rotate your full size spare until you find it. If its not the wheel then I would start my hunt for a bad velocity joint or wheel bearing.

I have the same issue on my 2010 AWD and one easy way to determine if it's tires/wheel related or driveline vibration is to switch into neutral gear when the vibration/noise is felt/heard. In my case the vibration almost completely went away during test drive with the Lexus tech when he switched into neutral so he concluded right away its a driveline vibration

I have option number "2" in a Z Profile. Ride great, i.e. road noise quiet, good traction on corners and I have 20,000 on them and they still look like new. Gas mileage is also good. 22 MPG overall and around 30 on open highway with cruise control.

Thanks. Good advice. I tried it and the sound/vibration remained. It's unlikely to be the tires since I'm on my second set of brand new tires. And the wheels are OEM. Not sure where to go from here.
