Michelin Pilot Road 3s...I joined the club

I have always installed the tires myself and static balanced the tires. The few shops I've inquired with about installing them for me do the same. I'm not sure if there is a spin balance machine out there for motorcycle tires or not.

There is. Both of the tire shops I've used over the past decade or so had spin balancers. From the outside, at least, they look pretty much the same as the ones at the car tire shop.
