The ones from 1975 up to to the late 1990s have the same tread and hubcap mould. They look so similar to your heavier type, they would be a very satisfactory replacement. You have a far higher chance of finding those in good unworn looking condition which look 95% the same, than your older 100% identical type in the same condition.

The first two photos are the actual genuine 6" front wheels that went on the VC models and others in the late 60s and early 70s.
The next two are the later type made from the mid 70s to the 1990s. You can see how similar they look and they will fit your mower.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
