Can someone supply information as to alternative wheels for a Peugeot 505 STi 1984 model?

It has metric wheels and the cost of the tyres is prohibitive.

this is an Australian model

The 505 was the last model from Peugeot that was REAR wheel drive. l KNOW it had 4 wheel bolts on each tire, not 3 bolts like earlier models (504). The size & shape of the wheel must fit over the front disc brake & wheel hub.

In English, the word ''wheel'' can sometimes mean the metal ''rim or it can mean the rim plus the rubber tire (tyre).
l believe the tire size was the metric size 185 R 15. A 15 inch diameter wheel rim?
Please tell me what tire size the ''Australian'' version uses? It was made in France or England for export to Australia. Perhaps the modern size is 185 70 R 15. This means that the height of the tire is 70% of the width (185 millimeters). the diameter will never change. 15 inches.

If u need Peugeot wheels (metal part only) that r NOT made by Peugeot, then u have a dificult question indeed. The bolt pattern & depth must be precise. l can find 505 rims here in Belgium & France, that r original Peugeot.
