Pretty sure NASCAR's top-level series has never actually raced in the rain. I know they started bringing treaded rain tires to the pair of road courses they race on a year or two ago, but I don't think they've actually used them yet.
F1 obviously does race on wet tracks with treaded tires of varying constructions ("intermediates", "full wet", "monsoon" ect.), but their tolerance for heavy rain has diminished a lot in the last decade so they'll stop a race if it's getting heavy or there is any standing water on the track.
MotoGP they'll switch bikes entirely in the pits if it starts raining since the tires are so tedious to change.
Anyway, that's all OT. Carry on.
