'04 LS 430, ~40K miles. I have had the car back to the dealer several times for slow leaks, and been told the wheels are pitted and I will soon need to buy new wheels. Bought new tires (from the dealer) and they said they polished the wheels prior to mounting tires, problem remains. Doesn't seem wheels with 40K miles, 5 years old, should need to be replaced, especially on a Lexus. Anyone seen problem and/or solution?
