The Marathon MTB comes in 57-584 (27.5 x 2.25) which is close to the fitted RR's... which are 2.35... and I ground the pedals with those anyway:rolleyes: But thanks for the tip, I will look into this more...
The Hurricane or the Marathon Plus MTB..... I can't make up my mind but am leaning towards the Marathons as Schwalbe say they are their most puncture resistant e-bike MTB tyre. https://e-biketires.com/
