RT-11 has a DD(X).SYS device driver which I have used
on a PDP-11/83 connected to a DLV11-J.  The connection
is straight through  with 10 pins to 10 pins (with one pin
usually omitted).

While the TU-58 tape will not have an RT-11 file
structure, you can at least read each raw block
and display the contents:

DUMP/TERM  DD0:/ONLY:nnnn

nnnn is in octal unless it also has a decimal point

Let me know if you need anything else to run the
TU-58 with RT-11.
