    Actually a car tire shop can easily balance the rear tire using one of their standard balancing cones.  One a recent trip I changed the tire at a friends house but his marcparnes balancer doesn't work on the rear tire of my SE.

    marcparnes balancers are great by the way.

    Using dynamic balancing on a motorcycle tire causes shimmy 90% of the time.

    A shimmy? How do you mean? Are you referring what might be called a death wobble?

    The zip tie method worked wonders when getting the Dunlop off but it was a fruitless effort for getting the Pirelli on though. The thing I found kind of odd is that they are both Z-rated tires but one was dramatically easier to deal with. Too bad I can't just fix the damage done to the Pirelli tire:



    I wouldn't think twice about using that tire.  The damage does not appear to be deep into the bead thus its fine.  The tire does not seat onto the wheel/rim that far down on the tire.

    I had 3 separate bike shops attempt to balance my PR4 front tire without success. There was an issue with the tire itself, but it wasn't due to poor balance.

    (Michelin has determined one of the belts was improperly wound around the carcass resulting in out-of-round on the right side of the tire) 

    Each time imbeciles at different bike shops used a dynamic balancer and put weights ONLY on one side of the wheel which caused imbalance at certain speeds, which resulted in out-of-balance tire shimmy.

    Death wobble is less likely caused by out-of-balance tires.  Tire shimmy is 100% caused by the improperly balanced tire.

    So, there is that.
