I think the 6.5 is what I based my tyre selection on originally using the manufacturers guidelines for rime size.The tyre size calculator indicates they are too big, but the manufactures specs say they will fit down to a 6” rim, perhaps A/T tyres fit a wider range of wheels. Still hoping I've haven't got it wrong.
