We suggest taking your bike to a local shop and have a professional technician do the work. We do not extend repair for its bikes nor does it have any shops affiliated with it. The proper pressure is printed on the tires. Tire pressure should be between 31 and 51 psi. If you don't have a gauge, squeeze the tire with your hand.
