Cheers for that, is there any way of measuring the width of a rim with the tyre on to find out, the stamp would be on the inside of the rim I presume, I was wondering about a 580 tyre as it will he used for ploughing but thought I'd keep them all on 650's.Ideally as above 16/18" fronts and 20" rear
520's (20.8) were sometimes put on 18" rims, but often only on 16"
420's (16.9) were sometimes on 15" rims, but often on 14".
If they are 18" and 15" you can squeeze the 650's and 540 on, if the tractor is not going to be subjected to heavy side loads and the pressures are kept up.
I think 580/70/38's and 480/70/28's are more forgiving of narrow rims, but harder find 2nd hand.
