When I need thicker tracks than standard, does track widths need wider?

Yes, in general, if you need the copper base thicker, the wider the track should be. One rule of thumb is that with a 18 µm copper base the track should not be narrower than 0.1 mm (4 mil) and with a 105 µm copper base the track should not be narrower than 0.25 mm (10 mil).
