Does a wheel size change require a speedo correction?

You keep advising people to change the size of wheels/ tyres to improve travel/ ride condition. When a different size wheel and tyre is fitted will the speedo need recalibration?

No because my advice is always smaller wheels with deeper profile tyres to put more cushion between the rims and the road for the same rolling circumference. If rolling circumference stays the same then nothing needs recalibration.
