Checked with the dealer and they said that it was tire noise. Some cupping existed even though there was lots of thread left.

Thanks. I'll update after I meet with the dealer. Tires are still original and have lots of thread left. Couldn't feel any cupping either.

I have a 2005 LS430 that seems to be making a louder than normal road noise at speeds above 40 mph. I notice a low sounding noise much like a wheel bearing that appears to come from the left front. No vibration but noise seems to follow the tire speed down to about 20 mph. I only have 27000 miles on this vehicle. I am going to take it to dealer under warranty but would like to know if anybody has an idea on what might be wrong?
