I doubt they'll offer on car balancing, but that should be necessary with the factory wheels at least and Lexus dealers do have good equipment technique for most balancing needs.

balancing
56 and 63 MPH are the speeds where any tire out of balance "dynamicaly" will cause a problem......any tire/wheel. The GS is an acccurate car and unforgiving of dynamic balance issues especially when you push to 18's and low profile. There is no more tire side wall to absorb any issues. Also, is the off-set of the new wheels the same as the original? If the off-set pushes the wheels outward even 5mm, you are adding a considerable amount of steering geometry to the equation.
If the steering wheel wobbls slightly from side to side at the critical point, it is a front , if the wheel seems to "vibrate" or pulse up and down it is a rear.
Get a GOOD dynamic wheel balance.

A couple of weeks ago one of my weights fell off my 20's in the left rear wheel. Ever since then I gotten new weights put on BUT I am still getting vibration at 55 mph. It is quite annoying.
Also let me ask you guys this, how often do you get an alignment for your car if you have aftermarket wheels? Say 19's or 20's?

On-car balancing
Tires should first be dynamically balance on a good, and properly set up, balance machine. Then they should always be spun-up on the car to validate. There are some pretty good on-car balancers out there but most cannot dynamically balance (placing weights in the areas of both the outer and inner rim edges (beads). Most on-car units can only tell you how much to put on and where in the circumference of the wheel.
