Larry: I suspect brand and type of tire have a lot more influence on road noise than tire size. Never owned two sets of tires that were identical except for size. So I can't tell for sure.
What I can tell you though .. Michelin Pilot VGTs in 215/60 -15 seemed very quiet. Dunlop SP - A2's in that same size were ridiculously noisy. My Potenza's in 205/60-15 are very new. And so far very quiet. My Nokian 195/65-15 WR are not perfectly quiet, but very acceptable. Ned Kleinhenz
