Not the Rohn 45 or 55. The only towers that will withstand such high winds 
are ones designed specifically to do so.  I was designing my Heights Tower 
to hold up to 125 MPH winds and constructed  a spread sheet to do the 
analysis.  They provide the engineering design analysis.  Last I checked 
some time ago it was available on their web page.  But that was some time 
ago.  I told my wife that the neighbors did not need to worry about my 
tower, their houses will blow away before the tower falls. I had planned on 
putting much more on my tower than I have so it is good for the winds we 
have around here in Kentucky.  They figure in appreciable margin in their 
design and by picking the right pieces you can build just about anything. 
And then you can add guy wires to boot.
I had to as for a custom made bottom sections when I added another 32 feet 
to my tower. I had to use much thicker wall aluminium tubing than was stock 
because I did not want to have to pour an new wider base for wider 
sections. No problem, they made them up in very short order.  If you have 
any questions just ask for Drake.  Strong towers are not cheap.
   I just checked their webpage look at this:
