Drum Heads--Why do they wrinkle?

i got a used set of tom tom heads from a friend. They are 16 inch toms. The head fits on the drum alright,but when i tighten the head it wrinkles up. why is that?

ANSWER

Hi,evandam--

It's difficult to know why without seeing the heads.
Normally that happens when the tension is not the same on all of the lugs. You might check the tension. If it is the same, then my guess would be that the person you got them from did not have the tension right when he used the heads and they may have stretched in places.

Best Wishes,
Lynne
