my E70 3.0 d comes with a stock continental 18" tire
I at about 34kilometer now and it is very noisy as well....

I have hear the Michelin has a much lower noise....
However, we I call up the local tire shop and notice it is
out of stock island wide.....
I do mostly freeway driving and do not do much driving on the winding twisty roads in the moutains....
with about another 3 to 4 mm of tread depth before reaching its indicator mark..... I am going to keep driving until the Michelin is avaliable
