for actual offset working out (of rim) google for "offset yokohama" (iirc)
best bet is borrow rims and try them (preferably with the same size tyres you want and same rim width), and then go from there...
btw, i think J is the bead profile of the rim.....
oh, as for second hand wheels.. if you know the width, measure the 'backspace' this is the important measurement anyways...
so take ruler and measure from the mounting face to the inner flat face of the rim (just below the bead)
ie 6" rim = 150mm wide. if the backspace (brake side) is 90mm, then the other side is 60mm. (90-60)/2 = +15 offset.
if you want to go from 6" to 7" rims then you still need backspace to be the same (give or take for sidewall differences)
