I switched to Continental Extreme Contact DWS and the difference is like riding on a cloud.

You are right, the threads are filled with overflow from the wheel coating process. So you will have to re-tap the holes. It's not difficult to do.

I just replaced my battery. I found that my battery tended to drain down overnight. The Lexus system is designed so that the battery must be close to a full charge (within a couple of volts)if it is not, then you will get a clicking sound or if the battery is too low, you won't get any sound at all.
