I don't know what width rims they were, but the front tire on the ST was a 3.50-19 instead of the more normal 3.25-19 for the time, so I would assume a 110/90-19 would be a fine fit, and as to the rear, again, a whole different bike. Not a 2.15" wheel and for sure you don't want less than a 130/90-17 rear. I really suspect a 130/90-17 is still going to be a smaller tire than original in circumference, but suspect a 140/90 too large. This again is the age old problem of obsolete parts. a 4.50-17 is fit, anything else a compromise one way or the other.
Low profile was not even dreamed of in those days. Gay looks in tires came in later times. :laugh:
I'll have to check on some resources I have and find out, or break out the measuring tape once I get the old tires off.
Working on lowering the front, and handlebars at the moment. New tires will come after that. Still considering 110/90/19 for the front, and 130/90/17 for the rear.
