Speedo Readjustment For KZJ70

[Yorkshire Devil]

I have just fitted 33x12.5x15 bfs to my KZJ70 and now the speedo is quite a bit out. At 20mph the car is travelling 30mph etc..

Is there any way to adjust the speedo without re-gearing with LJ70 2.4 front & rear ring & pinions?

Which ratio R&P will correct this?

Speedo is almost accurate now with no 7% tolerance. It turns out the APP I was using wasn't accurate when compared to my Garmin sat nav.
