Several years ago i put new 402 dunlops on my bike. When i picked them up from the installer i noticed a large amount of weight on the rear tire 7oz to be exact . We tried rotating the tire on the rim in hope that it would balance with less weight.All of the shifting did not help. I contacted Dunlop about the large amount of weight required to balance the tire and was told that it was within their tolerance . I took off all of the weights and put in 3oz of dyna beads .Rode the bike 8400 miles without any vibration or cupping. I now run the beads in all of my vehicles . As for the warranty I would not want to deal with their people.

 

Dyna beads worked for me...also used the stems dyna bead recommends.

 

I am under the impression that needing 7 ounces to balance a car tire is out of tolerance and that tire can only be used for off road/ farm use. Can't believe 7 ounces is OK for a scooter tire.
