You cant do it just by wheel size alone you need to factor in the exact size of the tire. The exact size is not the 255X19X30 its the physical measurement of an inflated loaded tire with a ruler. Tire Rack has this info for all the tires it sells. Somebody on the site might already have the combo & you are golden if not take a lot of measurements at the wheel opening to see how much clearance you have.
Just for a point of info the stock 313 19" wheels will take 245X35X19 & 275X30X19 with out rubbing with no spacers.
BTW if you have a warranty & they see wheel spacers you will have trouble from the dealer.
