Looking for some tires
A 195-60-15 is a very short tire for the front (45.72mm shorter than you have now). Even worse on dirt roads.
Are you sure that is the size you want? 205-65-15 would be a better fit and close to the stock size.
Other options for the front:
215-60-15
225-60-15
For the rear….. I'm looking at your other thread.

A 275-60-15 will be 2" (50.8mm) taller than what you have now and will require correct backspacing on the wheel and/or other modifaction.
A 235-60-15 would give you just about what you have now in the rear.
A 255-60-15 would be 1" (25.4mm) taller and a bit wider.
