17x7.5, has a made in england stamping but no definitive stampings for pcd, offset or centerbore. Look like RS Cosworth wheels but arent. Has a retaining bolt hole for the flat bolt hole cover (which I’ll post in another comment, which matches some 90s ford wheels) owner says they came off a Peugeot but my fellow french car enthusiasts say they definitely arent an OE Peugeot wheel.
Reverse image search didn’t help much as these are a very common style of wheel. I did see some BMW wheels that looked similar, including the bolted flat center cap and the round impression for the BMW logo, but those were 15" and unlikely to be 4-lug.
