I think that the hub or centerbore measurement for the 2012 Accent and a '93 Corolla are both 54.1mm.
That's according to this data:
Wheel Bolt Pattern Cross Reference Database and Conversion Guide: TOYOTA*COROLLA
OEM Wheel Size
Hub Center Bore
TOYOTA COROLLA 1988-02 Metric: 4 X 100
Standard: 4 X 3.94 14 X 5.5 12 X 1.5 54.1 H
And regarding the Accent:
2012 Accent stock 16" alloy weight info
"I was preparing my car for winter this afternoon and I took the stock 16" alloy off and I have found the below info."
"Bolt pattern: 4x100
Center bore: 54.1mm
Stock wheel with stock 195/50R16 tire weight 38lbs on my bathroom scale.
As per the tirerack.com, our stock tire weight about 18lbs, that makes the stock 16" alloy weight about 20lbs. The stock rim is HEAVY!"
The steelies you have for your 1993 Corolla ought to be a match for bolt pattern, stud size, and centerbore. If they are 14" wheels, as you say it's difficult to imagine the width on them, plus the tires you would mount on them, giving any trouble with fender clearance. You didn't mention the offset figure for your wheels but there again it's hard to imagine 14" wheels suitable for a front wheel drive Toyota being so different that they don't clear the brakes, etc. The offset for the stock 14" steel wheels of a 2012+ Accent is 45 I believe, or 46 (according the Konig wheels tire fitment guide) on a width of 5.5".
I'm not an expert but I'd guess if your wheels are anywhere even close to that offset figure, like 42, they should fit well.
