How many sets of rain tires did you have to use for the race weekend in OK?
How many sets do yo think other drivers used?
Since Norman was a double race weekend (qualify, heat and main on both sat and sun) I used 2 sets of rains. It looked to me that other drivers, even factory drivers, didn’t use more than 3 sets.
You have to remember though that we had 3 days of solid rain in Norman. That length of a rain storm is unlikely here in CO and thus 1 set of rains in the trailer would do.
Because the CSC only does single race weekends, I would highly doubt that you would need practice rain and racing rain tires.
