WHEEL SPECS

I,ve come to the realization that my TR has the original rubber on it. Obviously the 1989 vehicle needs new rubber and I'd like to replace the dated loooking factory stock wheels. Yes their the 5 lug bolt on. When I look online various sellers state that the 430 or the 360 wheels will fit a TR. Is this true? Bolt patterns appear to all be the 105 but the offsets are what concern me. When I ask the salesmen on the phone what the specs are for the offsets their answers range from vague to counterintuitive to the absurd. The yellow factory book refers to a 10inch and 8 inch J X 16 inch wheel. What does the J stand for? If any of you have "reshoed " your TR please hook me up with the specs. Which dealers gave you the best service? As always thank you for your help in this often foreign world of foreign automobiles.
