Hi Sawman,
I run Avon CR6ZZ's on the +4 Falt Rad, and on my '72 4/4.
These are IMO the best tyre you can get in a 70 profile, they offer fantastic amounts of grip in all weather conditions.
I'm run 175/70 R 15's on the standard 5 inch wide wires, there a wee bit wider (10mm) than the 165's on your car at the moment but you won't notice the diffrence, and there are no issues with rubbing ect, and my 4/4 is running an inch lower at the back and 2 inches lower at the front.
They come in two diffrent compounds, soft and very bloody soft (sport).
If you don't use your car a lot ie 5000 miles a year or less and don't take if on the track, then go for the soft (sport) compound.
If you do a lot of miles in your car or take it on the track I would go for the "harder" of the two, as the soft (sport) compound will last for about 10 laps before you need a new set of tyres.
The tread pattern looks like it should be rubbish in the rain but they are fantastic in the wet, lots of the drivers in the Masters Historic Race Series use the CR6ZZ as there choice of rain tyre.
Be warned there not cheap, if you shop around you can get a good price (I get mine from Brian Gateson at Techniques,
http://www.techniques.uk.com/mainframe.html ) , I can never understand the concept of buying a "sports car" and putting the cheapest crap tyres on you can find, you might as well buy a crap car in the first place.
One final note, if you plan on doing any trials in the Mog then get the firestone F560's as the Avons are rubbish off road.
Hope this helps
Jim
