Hi Max,
my only option with wheels for the Victas is cut the stubs off and weld new stubs on so I can use up some of the hundreds of wheels sitting here from all the other brands. Bit of a pain but all I can do. Get 4 wheels with hubcaps, weld the stubs on, fit the wheels, tie them together as a set and put them away for future use. Spend a few days just doing that and wheels won't be a problem for a while. I have been doing this before but with the lockdown I might as well use the time to stock up. I will also get 15/15 bases repaired/cleaned up ready for the next lot of warm weather and paint them so they can be stacked away and given plenty of time to dry/harden.
