Hi VM
Not sure what diameter rims suit but I just measured a front wheel of a colt major outside of bearing to outside of bearing and it is 35mm same as in your previous pic (tyre is 2.50 - 6) (bearing inside dia is 15.7mm approx) ( about 14 to 15mm from outer face of bearing to outside of rim). I have a couple here you are welcome to if they fit. Will need new tubes and tyres though.
