For understanding, there are lower limits of the weather, these are 0 and 100, for tires we set additional points.
The most important thing is the erroneous tire factor. At 0, we have a clear correspondence, the tires will change only when this level of precipitation is reached.
For example, Dry - 0, intermediate 22, rain 62.
If we set the factor equal to 30.
Dry 0+ (0-0) * 30/100 = 0 lower bound
Dry 0+ (22-0) * 30/100 = 6.6 which corresponds to 0.33 mm
In total, if the track dries, then dry tires will dress at 0.33 mm
Intermediate 22- (22-0) * 30/100 = 15.4 lower limit (0.77mm)
Intermediate 22+ (62-22) * 30/100 = 34 upper limit (1.7mm)
Intermediate will dress when the rain level drops by 1.7mm

If you changed “water factor” to water depth and used “mm” this would be easier to understand for the masses.  Keep the calculations in the background
