Only replaced tires. But the passenger back tire was replaced a 3rd time! After I got the new tires, I questioned the 17 balance weights on that tire! So they put another tire on that one. This tire has about 4 weights on it. They said they pulled wheels and tires from another NX, placed them on mine and drove it. Said it was worse than my wheels/tires.

Thats not right... I would stay on top of them.. It drove me nuts, but bring it back enough times and they will get it fixed.

Thanks. I am glad someone else has experienced this! I was beginning to think I am crazy. Keep you posted.

How did you get it fixed? My car vibrates at 82.
and they replaced the tires 3 times, 3 alignments and countless wheels balanced.. I even test drove a 2020 and i felt the vibration too!!
I have a 2018 fsport.nx300

When they mention balancing, are they doing a conventional balance on the tire/rims or are they doing "road force" balancing? Many times, you might still have a slight vibration which can be solved by the "road force" method which is done with the wheels/tires still mounted on the car. It's a bit more costly but does solve nagging issues. Beyond that, I would look to a possible bent rim.

Great to hear this! Have had the same problem, and it's bugging the hell out of me. Had tires balanced at a "road force" tire dealer. Don't know if he is properly using the machine, but the rumble has gotten MUCH better, but hasn't eliminated it. I am out of warranty, but will return to see if they detect a flat spot, and if it is within limits to correct with a tire re-mount. Crazy problem!

Any possibility improper torqueing is the cause?

As mentioned, you might have a rim that is slightly bent. I put new Pirelli's on a 17 GS350 through an independent tire dealer in my town.& had a vibration. They told me one of my rims had a slight bend in it.
Strangely, didn't have a vibration even with the bent rim & the original Michelins MXM4 I was replacing. They were still 100% smooth.
In any case, they rebalanced the 1 rim which fixed it somewhat,..but not totally smooth yet.

Had the tires ROAD FORCE balanced which helped some more, but still a nagging vibration at high speed.

Had the 1 rim "straightened" through Lexus dealer who uses an outside contractor. Vibration 100% eliminated.

These are finicky things...ultimately becomes trial and error.
