I don't vote for the ES100s either......they aren't BAAAAAD, but the aren't GOOOOOD either.

Overall noise is down, treadwear is supposed to be much better. I'm trying to remember the comparison of characterstics like turn in, sidewall stiffness, etc. I believe they are better in the wet, and turn in response was similar to ES100 which had a really stiff sidewall. Overall shoulder is a bit narrower than the ES100 in the 235 width. I have 235/45/17. I believe I could have went 245 and gotten away with it.

I have driven a C43 AMG with S-03s, but that car was a lot softer than mine, so I can't compare as well. I can't remember what the price differential between the two tires is anymore.

I'm sure didn't help you one bit. Maybe I can make more sense in the morning....maybe not!
