I thought I got a great deal for style staggered 20 inch style 87 rims......plasti-dipped them in black and then realized the tires were wrong size. they guy told me they came off 2005 x5.....i just assumed everything tires would be right size.

tires are almost new ...tempting to leave them on ...would it be safe? would they look OK? the guy also told me they were genuine BMW..he said bmw markings were lost when he powder coated them ( light grey)... is there any way to figure out if these were OE?

so what do you experts have to say?
