Have you checked it against GPS? I have basically the same setup and the bigger tyres have just corrected the usual speedo under-reading, now reads 101 at a GPS 100.
Note too that the odometer is calibrated differently from the speedo. From the factory a speedo typically reads +5% while the odo reads accurately usually within +/-1%.
