Yes, vibration in specific range of speeds sounds like wheel balance. With new tyre, you still have to balance. Without balancer, a lot of people just clamp an axle sideways in bench vise and spin wheel. It'll roll back and forth and settle with heavy spot on bottom. Tape weight to opposite side and spin again.
I apologize in advance if this is a dumb question, lol!

You say people clamp axle sideways in a bench vise and spin wheel. faq.ninja250.org recommends setting axle ends on jack or milk crates. So, why not, with tire off ground and level, just spin on the bike to find heavy side?

Also, tire appears to have been balanced at some point. Attached is a picture. Seems heavy.

Finally, when is a motorcycle tire bad? I have Dunlop K630s ‎100/80-16, 130/80-16 with cracking on the side. Tread looks okay. I did purchase Shinko SR740/741s. Just curious if the K630s are safe to ride on until I install the Shinkos.
