I do not think that tyre speed ratings existed in 1960, so the question is meaningless.
The only tyres specified were:-
88 Avon or Dunlop 6.00x16
88 Avon or Dunlop 7.00x16
109 Avon or Dunlop 7.50x16
88&109 Michelin XY 7.50x16 (radial)
109FC Avon or Dunlop 9.00x16
Later models (2a) included the option of Goodyear crossplies and Michelin Sahara, and for NAS models and those fitted with 9.00x15 Michelin Sahara tyres, 15" wheels. Also, 6.50x16 became an option.
It should be noted that the only manufacturers of radial tyres in 1960 were Michelin and Pirelli.
Australian assembled Landrovers would have been fitted with locally made tyres, and in 1960 these probably would have been Goodyear or Dunlop, most likely RTM or Roadtrak or similar. Radials were virtually unheard of in Australia in 1960, and I did not hear of them being fitted to four wheel drives until the mid sixties, and then only for sand work - they were considered to be much more prone to damage and were also very expensive. I don't think other offroad radials appeared until the 1970s.
