I’m needing a set of main wheels for my Avios Grand Tundra. Also looking for the optional snow skis and optional water floats if anyone has for a good price.
As for wheels, you'll probably just have to search for the size and type you are looking for. These are usually sold generically by many companies. I suspect the ones that came with the kit are measured metrically ( in mm ) but don't forget to look at similarly sized imperial measured ones also.
