Tires The inter-axle ratio; Shibaura SD4000AD-0

[Jompa Norway]

May anyone tell me what the inter-axle ratio is on my Shibaura (1978). Or give me a tip for finding it (on the web)?? It's needed for new tires.

Beforehand thanks.

I presume you mean the ratio of the front axle to the rear axle for proper tire diameter. If so, try a major ag tire supplier.
Even if you get an answer there I would double check it with the factory or manufacturer.
This is too important to get it wrong.
