7.5 Tires and Tubes

1. Tires
Electric bicycle tires are available in many designs and specifications, ranging from
general-purpose designs to tires designed to perform best under very specific
weather or terrain conditions. If, once you've gained experience with your new E-bike,
you feel that a different tire might better suit your riding needs.
The size, pressure rating, and on some high-performance tires the specific
recommended use, are marked on the sidewall of the tire. The part of this information
which is most important to you is Tire Pressure.
WARNING: Never inflate a tire beyond the maximum pressure marked on the
tire's sidewall. Exceeding the recommended maximum pressure may blow the
tire off the rim, which could cause damage to the bike and injury to the rider and
bystanders.
The best and safest way to inflate a bicycle tire to the correct pressure is with a
bicycle pump which has a built-in pressure gauge.
WARNING: There is a safety risk in using gas station air hoses or other air
compressors. They are not made for bicycle tires. They move a large volume of
air very rapidly, and will raise the pressure in your tire very rapidly, which could
cause the tube to explode.
CAUTION: Pencil type automotive tire gauges can be inaccurate and should not
be relied upon for consistent, accurate pressure readings. Instead, use a high
quality dial gauge.
