Vibration @ 120 km
#16
No vibrations at 120 or higher with mine, Mind you it is not a sport but executive model
Hade it to 200KM and nothing , it was very stable, mind you wind noise was present inside

TC3500 Mounting Machine
Using the Hunter TC3500 mounting machine, optimal matching of the tire alignment relative to the wheel can be done with higher accuracy and help to eliminate vibration problems.
GSP9700 Balancer
The Hunter GSP9700 Road Force measurement balancer road tests the mounted tire and wheel to effectively measure the uniformity of both and greatly reduce the amount of weights required to provide the smoothest possible ride.
The GSP9700 Vibration Control System includes Hunter's exclusive Road Force Measurement System to help detect potential tire uniformity causes of vibration that are not balance-related. This system utilizes a "road roller" which applies up to 1,400 pounds (635 kg) of force against the wheel and tire assembly to measure their combined uniformity. This simulated road force test helps verify if the assembly is "round" when rolling under load.
The GSP9700 Vibration Control System can also measure lateral and radial rim runout (out of roundness or side-to-side movement) to identify and separate wheel runout from tire runout. The system then calculates the contributions of the wheel and the tire to a potential vibration and presents the service specialist with easy-to-follow instructions on the appropriate corrective actions.

From my (several) experiences with vibrations at 70+ mph (115+ kph) with older cars or having swapped to new tires, it has been either due to a warped rotor or an improperly balanced wheel/tire. The vibration is typically felt through the steering column or under your seat, or a combination, depending on where the vibration source is (front vs rear vs L/R). I would insist to your Lexus dealer on checking each wheel/tire for a perfect balance attainable with the right equipment such as Hunter Roadforce.

So I would say that it's pretty safe to say that it's not the tires or the balancing.

My NX is smooth as silk ......not even almost a vibration and yours is 100% unacceptable.

Sorry to be a stickler in the interest of helping, but it really does make a difference. When I had my 2RX a few years back and I got a new set of tires mounted and balanced at a local Canadian Tire, two of the wheels vibrated at 70 mph+. I brought it back to them twice and still the same issue. They advised me to go to a place that has the Roadforce equipment. Skeptical, I ended up at a local Toyota dealer since they had the Roadforce equipment and were able to detect the wobble and apply the weights in the exact spot that the CT equipment could not detect. Resolved. Smooth ride afterwards.

Was this ever solved?
My first thought is that the tire is out of round, in which case no matter WHAT you use to balance it, you won't be able to fix it.
My second recommendation would be to tell the "glitch" dealer they are ridiculous and file a complaint with Lexus because no dealership should say something like that. I don't care if its Lexus, or Toyota or Chevy, or any. You paid for a service and if the car wasn't right from the beginning, it is their job to fix it.
I would also say, as MR2 stated, there are dealerships that have laser balancing. If they can't balance it, there is a larger issue. I would recommend you speak with a local chevy dealers and ask if any of them are qualified to mount and balance tires for the new Z06. Dealerships that can work on the Z06 were required to buy a whole new laser balancing machine to accommodate the wheels on that car. If they can balance the tires on a 200mph border-line super car, they should be able to fix yours.
I would personally ask that the tire be replaced. If its replaced and the issue continues, then its something in the drive train, and then you start from there.

I went to the dealer yesterday and they checked the tires on a roadforce balancing machine and one of them came back as out of spec.
So now I have to go to walmart and get the tire replaced.
Thanks again!

If you did realize that, and if you haven't driven at 75 mph or can't even imagine doing so then, yeah, you're getting old!
