GPRO Tyre Wear numbers
Assume temperature of ~22 degrees and using low-ish risks (5, 5, 5, 5)
Wear Level | Compound | distance (km)
very low | extra soft | 120
low | soft | 135
medium | medium | 140
high | hard | 150
OK so with those as baselines:
for soft and medium:
add/subtract 10km for each 10 degrees under/over
add/subtract 10km for each level of wear under/over
for extra soft / hard:
add/subtract 15km for each 10 degress under/over
add/subtract 15km for each level of wear under/over
My experience with wear vs risks is not the best, but I would say that, anytime the driver is using a risk 10 points off the baseline I've given above (5), then take off another 10km from the tyres.
remember these are all cumulative. eg: if the track wear is medium, and the weather is 35 degrees, then the extra softs will only do about 75-85km. Even less if you're using higher risks.
