Can anyone offer insight here?

This Mathematica expression gives 3 solutions to the equation.

Solve[Pr == (8*Tr)/(3*vr - 1) - 3/vr^2, vr]

The problem is that there are 3 Real solutions, and Mathematica is giving
solutions with (granted a small) imaginary component.

And hitting it with  a full simplify is just not a good idea...

Any help?
