This summer I bought a 99 300M with less than 18,000 miles. Because of a shake in the steering wheel they replaced one tire then, because of a bad belt. Just had tires rotated and the shake is back. Haven't called the dealer yet. Have others had similar problems? Makes me wonder if Goodyear hired Firrestone's Quality control department. The tires are Eagle LS 225/55R17. Ken Krull New Paris, In.
