Chevrolet C8A HUW question

[kevinT]

I have been asked my a fellow modeller to ask a question for him.
He is making a 1/35th scale model of the Chevrolet C8A HUW and has a question regarding the tyre sizes.
The kits used are the Italeri Chevrolet 15cwt truck and the Plus Model HUW conversion set. The tyres provided are the 16" type but all references state that they should be 13" for the C8A.
His question is where the 16" size tyres ever used on the C8A HUW if yes fine ( any pictures ). If no, has anyone ever made this kit / conversion and which model company makes 13" tyres in this scale.
Thanks for any help or suggestions provided.


Cheers
Kevin
