I have a 99 GS400 with the stock 17 inch wheel and tire combination. The tires are brand new, with less than 100 miles on them so far. They are the Bridgestone RE-730's, and the first thing I noticed about them is that they are NOISY in comparison to the stock Bridgestone RE 030 tires.
I also notice a distinct vibration at 55 to 60 miles per hour, and it disappears at about 80 on the high end. It does not vibrate at any speed slower than 55 or 60.
I have heard that there is an adjustment to take out excessive slop in the rack and pinion, but can't remember where it is I saw it. I wished now that I had the 16 inch wheel and tire combination. It is not as sporty looking or handling, but the ride is supposed to be smoother, and tire life is supposed to be considerably longer. An website called www.aaarims.com is supposed to have the stock 16 inch wheels in stock. I might just buy a complete set of these to augment the 17's I have on the car now. I called a local Lexus dealership, and the service department did NOT know of an adjustment of the type I described.
I would appreciate any comments or advice that anyone can give me in that regard.
Thanking you in advance,
