I have Road 5 GT's on my K1300GT with 38/42 pressure. Tires have about 6K miles on them and I notice a loud humming sound from the front tire on some road surfaces. Never had this happen with Road 4 GT's.
I get the humming at about 40mph on the Road4 GT on my R1200RT. Not as bad as the Metzler Roadtec 01 though.
The Road 4GT is a great tire for 2 up. The Metzler is also, just too loud.
