I am curious where you read Triumph made a 750cc T120R in 1968? I am certainly not familiar with that being the case and I have read a lot about 1968 T120R's since I have one. I don't believe Triumph produced a 750cc Bonnevillle until the early 70's.
Front tire size for a 1968 T120R is 3.25 x 19 and rear is 4.00 x 18 per the owners manual.
