96 going for emission testing in Ontario

[guessguy]

Any fellow drivers here from Ontario? I'm going for an emission test later this month and wanted to know if they will be using the OBD II or spin the wheels? The driveclean.ca site says 1998 vehicles with OBD will be used, but my 1996 has OBD II on it. Reason is I hooked mine up to an OBD II reador and using my laptop software, everything passed well. I wonder if its the same thing they use.
I also have 315/35/17 wheels on the back so will that cause a problem on the spinner?
