I do that too, when I am by myself, but being an old guy, my hearing is not great anymore, some frequencies are better than others and unfortunately, I think the road noise is just one of the frequencies I hear better than others.
Not just me, though.... these tires get a 2.2 out of 5, and most of the reviews complain about the noise. http://www.carreview.com/product/parts/tires/goodyear/eagle-rs-a.html
