Thanks

Skt
If you put Xtx tyres than speedometer error will increase about 2,5%. (130/80 => 160/60)
If original error is 7% than error with Xtx wheels is almost 10%. It is up to you if you can live with that.

I have bought speedohealer because I usually use 14/48 sprocket with XTR wheels (better for offroad) and 15/45 with XTx wheels.

Here you are one calculator about tyre size change effect:
