What size of rims fit on a 1996 Vw jetta?
You want to make sure that your ET (back spacing) is between 35 and 40-45ish. Any lower they will rub on the caliper and too much higher will make the wheel stick outside the fender (unless you want that look). Depending on which engine your car has makes a difference on what size the brake rotor is. A 2.0 liter can go as small as a 14″ wheel; VR6, no smaller than a 15″. You can put up to 19’s on it, but 18 and 19 wheels look out of proportion. Tirerack.com has a neat viewer so you can see what the wheels they carry will look like.
