Wrong PSI costs you
more than you think
Most e-bike riders run the wrong pressure without knowing it. Your tires might look fine, but the numbers on the sidewall are a range — and where you fall in that range depends on your actual load.
Battery range
Under-inflated tires create more rolling resistance, draining your battery faster on every ride.
Pinch flats
E-bikes are heavy. Running too low on pressure is the #1 cause of pinch flats — and e-bike tires aren't cheap to replace.
Tire longevity
Running 10% over the optimal pressure wears down the center tread faster. Too low and the sidewalls take uneven damage.
