Why must motorcycle tire inflation pressure always be measured when the tires are cold (before riding)?

1. Hot tires cause electronic tire pressure gauges to short-circuit and melt
2. Tire pressure drops significantly as tires get hotter due to air condensation inside the carcass
3. Riding generates internal friction that heats the trapped air, causing pressure to rise by 20–30 kPa (3–5 PSI); measuring cold provides the true baseline manufacturer specification
4. Cold measurements allow the rubber to absorb ambient nitrogen from the atmosphere
