Rolling resistance is the drag you pay every revolution—higher when tyres are soft or small. This guide shows how to calculate rolling resistance for e-scooter tyres using pressure, wheel size, and mass inputs from the tyre pressure tool.
Benefits
- Rolling multiplier rises with bar below recommendation.
- 8″ vs. 10″ wheel diameter shifts baseline loss in the model.
- Links rolling resistance to Wh/km and commute range impact.
How it works
- Measure current bar and note recommended pressure from the tyre or deck.
- Enter wheel diameter (in) and rider mass (kg).
- Read adjusted Wh/km and range penalty %—proxy for rolling resistance cost.
FAQ
How do I calculate rolling resistance for e-scooter tyres?
In planning terms, compare Wh/km at current pressure vs. recommended bar. Under-inflation increases a rolling multiplier in the model—each bar below target raises energy per km. The tool outputs Wh/km and penalty % as practical rolling-resistance indicators.
Why is rolling resistance worse on small scooter wheels?
More revolutions per kilometre mean more tyre carcass flex cycles. Contact patch squirm and casing hysteresis scale with under-inflation. The calculator adds extra loss below ~9″ diameter—matching many 8″ solid and pneumatic commuter setups.
Do solid tyres eliminate rolling resistance?
Solid honeycomb or rubber tyres avoid pressure loss but often run higher baseline rolling loss than firm pneumatics. Use recommended bar on pneumatics as the efficiency benchmark; compare Wh/km before switching tyre types.
Technical specifications
- Rolling loss proxy: Wh/km vs. firm-tyre baseline at same mass.
- Under-inflation (bar) = max(0, recommended − current).
- Wheel size (in) and rider mass (kg) adjust the model.
