Both TCR South America and TCR Brazil announce they will use Kumho tyres.
They already supply control tyres to TCR Europe, TCR Denmark, TCR Eastern Europe and TCR Spain
With TCR Europe using them this year, I wouldn't be surprised if Kumho becomes the control tyre for the TCR World Tour.
If that's the case, you could end up with TCR World Tour on Kumho and local drivers using the control tyre already in place by the promoter, unless it's Kumho as well.
