Should PMs create wireframes, or does it constrain the UX designer?

As product managers we are responsible for the overall solution and it is natural to feel the urge to control every aspect of it. Understanding the problem space is crucial and wireframes/prototypes can help immensely.

But there is a tension: can a product manager creating wireframes that are handed to a UX person sway their judgment? Does handing over wireframes create an invisible boundary that both the PM and designer hesitate to cross?

Does the answer change based on the maturity of the UX person? Are there other alternatives for a product manager to explain the possible solution beyond wireframes? Or should we just focus on the problem space and leave UX to the experts?
