I have just recently ordered new Michelins Primacy MXM4 for my 2002 E430. My wife drives this car and the last two sets of tires worn out on the edges. The centers were fine. These are 235/45/17. They are what I consider low profile. I know the tire pressure is on gas lid, but what about what the tire recommends? Don't want to ruin my new Michelins; they don't give them away!
