Well everyone - do I feel like a schmuck. Today I finally said what the hell - I went and bought some Michelins. Guess what? Problem solved. After all I've put you poor guys through
Geesh. Sorry! Anyway, I learned a lesson here. I'm just really surprised that tires with only 10k on them would give me fits. And I just bought Continentals for my other C280 - and the ride sucks on it too. I was amazed at the ride; smooth as silk, no bone jarring over bumps, and the car is responsive again. Wow. Anyway, thanks for all your help, I do appreciate it! I should have listened to the masters: Steve, et. al thanks.
Phew - I feel better now - the car feels like a benz again.
