I put brand new Michelin Destinys on both of my Es300's. (97 &2002) 97 is 15inch....2002 is 215-60-16
They have been excellent, quiet, and so far great in the snow, vast vast improvement over bridgestone potenza.
I was debating between goodyear triple tread, about same price, and were ranked #1 by consumer reports I believe, but the tireplace(manager i've known for 10+years.....was adamant those tries aren't lasting the full mileage, but the desintys were easily going the full 85k miles they are stated for, if not more) his advice might not be scientific, but the man has been in the business his whole life, and has always taken care of my car tires. I believe the destinys 16inch go for about $117 a tire, and costed me about $550 otd, with 4yr warranty too.
