Heidenau K76 fitted... Vibrations while braking

[2wheelnut]

Just wondered if anyone has K76's fitted. I just had mine put on and notice a heavy vibration when slowing. Happens around 20 MPH and only lasts for that bit. Just checking to see if they mounted the tires badly. Otherwise at speed they are smooth. Anyone else have the same thing on these tires? I chocked it up to the Tread Pattern but has me thinking it's something else.

No experience but I would make sure the tire was installed in the correct rotational direction and double check the balance. Sometimes an imbalance will only be noticeable at specific speeds. I had different tire once that vibrated on deceleration but not under acceleration that turned out to be way out of balance.
