I just replaced a set of noisy Goodyear Eagle GT's on my 2005 GS300 with Mechelin Pilot Exalto's. I am really happy with the resuts. The Goodyears were V rated, Michelins are H rated. I still feel secure and confident with these, exept without the noise, harshness and discomfort. Goodyears had 25000 miles on them. I had them from 15000 and even then the noise was too much! Time will tell how long they stay quiet. Tire Rack gives them high ratings.
