Car lagging after tyres changed

I recently changed all 4 of my tyres from run flats to standards; and also had an alignment done, on my 2016 Q30 2.2D auto…..
Not sure if linked or purely a coincidence, but since then the car doesn’t seem as good of a drive as it was previously, now seems a bit sluggish, gear changes are lagging a bit but were pretty smooth before; and I’m fairly sure my fuel consumption has reduced.
I’m being advised to reset the auto gearbox so it learns new driving styles, but I’m worried this may make matters worse.
Anyone had similar experiences?

Did you consult a trusted mechanic? Maybe that would help.
