The standard tires we offer on our bikes come with a rated maximum pressure. We recommend to use a pressure that is at least 20% less than the maximum as this will provide added suspension and diminish the shock and vibration the bike has against the road. Also while riding the pressure tends to increase as the tires heat up.
After riding you will find a preferred setting that will adjust to your load and enviorment.
Note: Always inspect your tire is seating properly around the rim before adding air. The tire bead can move when the pressure is low. Use a floor pump or hand pump (do not use a standard air compressor as the volume is too high and the pressure is set in a different trigger)
Also check your tire labels to confirm the maximum rated pressure is correct as sometimes the models can vary due to provider updates.
