10.50x16 tyres and more

[Erwin]

One of the relevant facts in my decisionmaking on the possible purchase of a Dodge D-15:

Where would I get the appropriate banana type 1050x16 tyres, new (or almost new)?(I live in Austria.)
How much would they cost?

And: Is there anything specific to this truck that is likely to be broken/worn?
Gordon already helped me a great deal, maybe Matt knows more.
Sorry if my answer takes 1 or 2 days, have email only at workplace. Many thanks.
