I appeciate everyone who has tried to help.

I agree there is something out on the car, maybe a wheel bearing, control arm, but whatever it is, I can't find anyone who can find it, so I sold the OEM 18s, not sure if they were out of round ( I doubt it ) but they were never going back on my car. I will now sell the 18" Continentals, if I can, or just keep them for the next owner of the car.

I will find some 17s, get some new tires and hope the wandering issue disappears.

 

Why buying expensive tires? I have been using Kumho tires on my LS 430 and previous BMW740 quite successfully.
I recommend it.

Stu, I checked at Sears. There will be another 160 dollar rebate but they are not sure when, with the Sunday family sale I got 4 gy's after reabte for 440.00 plus balance. They are as quiet as my Primcay H's and handle better. Good luck!

I test drove a LS with Kumho Platimum ectasa or something, terrible tires. Glad someone else has had good experiences.
