Can't help the OP, but I can give you a bit of advice, personal advice. I also purchased the V-61 tires. I bought them for my 782, and knew I wouldn't be mounting them myself.
I DID have the wheels pre painted, and took them to "my tire guy", and had them installed. He used tire irons, a lot of soap, and within fifteen minutes I was paying the man and on my way home with mounted tires and minimal paint chipping.
Nothing a little paint, and brush couldn't fix.

My advice. Take them to a reputable tire "guy/establishment.
