These new resin wheel set from Royale Resin includes 4 wheels, all of them treaded and are a  direct replacements for the kit wheels.  It will be a simple job to remove them from the casting blocks and the connection point will be the weighted bottom of the tires.  

The tires are finely detailed with realistic looking treads as found on the full sized tires.  The wheels have full detail on both sides......this is crisp realistic looking detail that includes lug nuts.   

If you are building a 1/48 Mirage IV, then you should definitely consider adding these resin wheels.

You can buy this set directly from Royale Resin.
