1993 Wagon came with these 15" aluminum wheels - the previous owner said they were sold to him by a Volvo enthusiast in Pennsylvania.
1990 Sedan came with these 15" wheels. I'm not sure what they're made of, but they look like they could use a polish. They are in the Corona style but the 240 ones aren't a match for this wheel. Mine also require a small (5mm) spacer to get good clearance.
That tire brand is mysterious too but let's not talk about it. They'll get replaced soon.
Thanks!
