Are you racing at TQ?
Yes at TQ.
We had the same issue starting around December with the tires, even on cold nights.
But it wasn't always this way, last fall and before that, Magenta was still the go.
Took a while to sort out what was happening.
Up at Nor-Cal where they use Paragon it's not an issue.
I didn't need Yellow up there.
