Large Scale wire wheels

[Gaspode]

Does anyone know of anywhere I may be able to buy some wire wheels in large scale? I'm thinking of 15" wheels in 1/4 scale, so they'd be around 3.75" diameter?

The idea of making up 5 72-spoked wheels myself is frankly a bit daunting.

Blimey, that's going to be some model.

The biggest I can find are 1:12th.
