656 tread width

Thanks,

Lots of things come to mind.

International or Farmall? Narrow based wide front or the really wide one? Original front-end or a replacement/aftermarket unit?

Tire size? Have the wheels, knees and/or hubs ever been replaced? Many parts interchange and look the same but are actually different.

Bulldog effect: Are you measuring at the ground or the top of the tire?

And lastly, owners' manuals are always written, published, packaged for shipment and sent out to destinations before the first unit is even actually built. So, finding a mistake or two in an owner's manual is not all that rare. :>)

It is the Farmall version. The tire size is 7.50-16. I think the knees and hubs are original because I can find the correct IH part numbers stamped on them. I am measuring at the top of the tire -- where should I be measuring?

Also, since the tread width is measured from center to center of the wheels, does tire size even matter?

Do you know what the width of the center tube should be? Mine measures 42.5"

Thanks,

Don

There is also very likely a difference if you have 34" pressed steel wheels. There could be a difference if someone has replaced the 38" rims with newer or wider rims
