I just bought some 16" Circuit 10 from Rota and i need hubcentric rings. I had some 73x56.15 but they do not fit at all and will have to return them. I did my best to mesure the width i would need but it would be greatly appreciated if anyone could tell me the exact diameter.

It should be something close to 66.25x56.15..

Thanks alot.

 

Anyone?
