I installed Michelin Road 5's front & rear just prior to departing on a 1500-mile cross-country. Out on the Interstate I bring it up to 80mph and I can feel vibration - not heavy vibration but just enough that it bugs me. When I push it to 90mph more vibration. I feel it in the handlebars so I'm assuming it's the front tire. Took it back to the tire shop and had them re-balance it. They put allot of weights on (see attached photo - there's 4 more on the other side of the wheel). Got back on the Interstate and still some vibration though not as much as before. Question #1: Shouldn't a BMW K1600 GTL be smooth as silk up to and over 100mph without vibration? Question #2: Per the attached photo, does anyone have this many weights on their front wheel? I'm thinking either their speed balance is faulty or the tire is defective. Anybody ever have an issue similar to this? I'm thinking of taking to the BMW dealer and have him re-balance it - even if I have to pay for it.
