[W126 Coupe] satish et al; what tires 18" AMG

[John Dunne]

I am asking for tire recommendations for AMG Aero II's 18" staggered   
with godawful noisy Dunlop SP9000s. I would like to swap the wheels  
for 17's same  AMG but can't find a trader. so either go back to the  
stock or get new tires. What are you running these days that is more  
quiet than fast for long highway cruising ? TR was not much help with  
this set up on the 126.
thanks
JD
