i think its been more than a week since you changed your tires to 195/60r14
this tire size already has a diff of 1.11% over ur original circumference.
so the actual 135 kms of the Ankola road will show 136.8 km on ur speedo if its right.
but since its showing 135.6 instead of 136.8 means it already has an error .
so with ur stock tires the error will be more

Dude, simple mathematics. My new tyres are bigger by 1.11%. So, it is bound to show more than the old tyres at any given point. I'f my car does 135.6 (over a 135km run) with a tyre circumference of 72.88 inches. A tyre with a circumference of 72.08 inches should read 134.11 kms.
And don't forget that the distance between your wheel hub and the road is the actual radius of the wheel and that can vary with increased or decreased tyre pressure.
It is practically not possible to get a therotical result. There are too many factors that come into the picture when you do it practically.
