The car is a new (for me) 2007 E3504M, 35K miles, with Sport Pkg. It has new Michelins in the MB recommended size: 245/40 R18. After 13 years in a Saab 9.5 with GY Assurance ComfortTred tires, I find these MB low profile tires give a very, very harsh ride (the story about driving over a quarter and being able to tell Heads or Tails applies!). Can anyone recommend a higher profile tire that offers a bit "softer" ride?? MTIA.
