There are different types of tires which can be used, depending on the intended purpose of the cargo
bike.
On the tire wall, the tire size is indicated in millimetres or inches.
● Notation for millimetre indication: width - inner diameter, e.g. 62-584.
● The pumped up tires are 62 mm wide, the inner diameter is 584 mm.
● Notation for inch indication: Inner diameter × width, e. g. 27,5“×2.4“.
● The pumped up tires are 2.4“ broad, the internal diameter is 27,5“.
The tires and rims are not airtight; rather the air is retained in the inner tires with the help of an inner
tube which is filled with air via the valve. Contact a Carqon dealer if the tires show signs of cracks or
damage or if the profile is very worn.
Warning : Ensure that the tires do not show signs of cracks or damage due to sharp
parts or sharp objects. Check the level of wear to the tire profile and ensure that
the tires are not excessively worn. Slipping can be caused by worn tires.
10.3 Valves
Carqon cargo bikes are equipped with the following type of valve: Express valve (Dunlop): secured
with union nuts; rim holes 8.5 mm/0.3“
• Turn the upper knurled nut (1) in an anti-clockwise direction towards the top, to let air out of the
tires.
• Completely unscrew the lower knurled nut (2) in order to change the valve insert.
• Turn the lower knurled nut (3) clockwise as far as it goes in order to close the valve.
Depending on the type of valve, you will require a pump to pump up the tires with a suitable valve
connector or a suitable adapter. To purchase an air pump with a suitable valve connector or adapter for
your valve, contact a Carqon dealer.
10.4 Tire pressure
On the tire flank you will find details concerning the maximum pressure for the relevant tire. These
details are given in PSI, kPa or bar depending on the manufacturer If the tire pressure is too high, the
inner tubes may burst during your ride or the rims may break and at an excessively low tire pressure, the
inner tube may become damaged. Take note of the details concerning the maximum and minimum tire
pressures.
A tire pressure corresponding to the indicated lower threshold is suitable for:
● Light riders.
● Riding on uneven surfaces.
● Riding with high level of suspension comfort at higher rolling resistance.
