These resin wheel set from Royale Resin includes four wheels, all treaded and are a  direct replacement 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 and sidewall detail that includes as found on the full sized tires.  The wheels have full detail on both sides......this is crisp realistic looking detail including lug nuts etc on one side.   

If you are building a 1/48 MiG-23, then you should definitely consider adding these resin wheels.

You can buy this set directly from Royale Resin.
