Tires???

I got a 1993 Oldsmobile Cutlass Supreme SL, with the 3.1L V6, just curious what your OEM factory tire sizes are, mine are saying P215\60R16 But when i looked online for new tires it says they should be P225\60R16, Are the P215's optional sized tires, or are they supposed to be 225 and i just have the wrong ones on there? The current ones seem to fit and look fine, just curious how things are done with the tires, thanks

one is shorter then the other on the 215/225.
Look on your drivers door, the sticker should say which it is.
Probly is the 225 though.
