Would stock OEMwheels from 1997 Civic fit on my 1990 Civic? Well, would all OEM wheels fit on any Civic as long as the bolt pattern matches?

Im pretty sure they will.

Your tires would be about .80 inches larger in diameter if you originally had 175/70/13 tires. (The OEM 97 Civic tires were 185/65/14). This means your speedometer would be slightly off.

any 4x100 bolt pattern wheel will work, tire size is the key to compatibility. for it to "work" you just need a close tire size.
