Properly inflated tires will roll more efficiently and be less likely to puncture. Pump up your tires to the pressure within the range recommended on the side of the tire (40-60 psi for most Blix Bikes). Use a floor pump with a gauge. Weekly pumping is recommended, and a monthly minimum. Lighter riders can run a pressure on the lower end of the recommended range, heavier riders and riders carrying cargo should run pressure on the higher end of the recommended range.
