It might be a good idea to put on your survival suit if you're thinking of taking your vehicle out on 10cm's of ice
As long as ice stays well below freezing, its thickness is directly related to the weight it can support, this table, provided by the National Research Council of Canada, shows. Ice loses its strength as it warms to 0ºC and cannot support as much weight, regardless of its thickness.
