Hope this post is OK - I know it's not strictly TAMIYA but I am getting desperate now. I can't find any replacement rear tyres for an early gold tub RC10 with the 3 piece wheels. I've looked world wide for a month or so with nothing. The rims measure just 42mm in diameter, quite a bit smaller than anything else I've been able to find. Anyone out there restored an early RC10 and got any ideas as to what can be used ? Do any other makes fit ? Dont mind something non genuine as long as it looks somewhere near right. Thanks.
