What I meant was that tensile strength of Al and Mg alloys do not vary by as much as the fracture toughness does.

Bearing in mind that the properties can vary with various heat treatments:
ZW3 Mg alloy UTS is between 295-305 MPa
WE54 Mg alloy, 275-285 MPa
6061 Al alloy UTS is between 241-320 MPa
A357 Al alloy, 262-345 MPa

Similar of course to the examples that you used although I suspect that the ones you cited were some sort of average value?

Of course though, yield strength in reality is more important than ultimate strength because you don't want your wheel yielding while in use. So then for 6061 you are looking at 193-290 MPa and for ZW3 you are looking at 295-305 MPa, obviously linked to whatever the UTS is (can't have higher yield than ultimate).
With both materials if you go to either extreme you can end up with a larger gap (c.100 MPa) in performance but with it being one of the most important properties I think it is acceptable to assume that heat treatments would be done to get near the high end of the range (unless they are super cheap wheels).

These values taken from commercial materials selection database software.

Haha, imagine how pointless it would be using titanium for kart wheels :)
