Here is what I am up against. Three wheels: one 18 inch off the 12/4 "Y" van, 16 inch off the 12/4 sedan, 17 inch off the Morris 8 van all in production together. Don't you just love the Poms!
From the left:
18 inch correct "Y" wheel blocked up to about the height of 5.00X18 tyre
16 inch car wheel originally 5.00X16 but this has 6.00X16. Jeep tyre also fits OK.
17 inch wheel of the 8cwt or "Z" van with 4.50X17 tyre
Lots of Tilleys had non-directional pattern and I suppose the "Y" van wouldn't look too bad with them.
