4.3.10 Rims, tyres and tubes
4.3.10.1 General

Non-pneumatic tyres are excluded from the requirements of 4.3.10.2 and 4.3.10.3.
4.3.10.2 Tyre inflation pressure

The maximum inflation pressure recommended by the manufacturer shall be
permanently marked on the side wall of the tyre so as to be readily visible when the
latter is assembled on the wheel. If the rim manufacturer recommends a maximum
tyre inflation pressure, it shall be clearly and permanently marked on the rim and

also specified in the manufacturer’s instructions.

It is recommended that the minimum inflation pressure specified by the tyre
manufacturer also be permanently marked on the side wall of the tyre.

4.3.10.3 Tyre and rim compatibility

Tyres that comply with the requirements of ISO 5775-1 and rims that comply with
the requirements of ISO 5775-2 are compatible. The tyre, tube and tape shall be
compatible with the rim design. When inflated to 110 % of the maximum inflation

pressure, determined by the lower value between maximum inflation pressures
recommended on the rim or the tyre, for a period of not less than 5 min, the tyre
shall remain intact on the rim.

4.3.10.4 Rim-wear

In the case where the rim forms part of a braking system and there is a danger of

failure due to wear, the manufacturer shall make the rider aware of this danger by
durable and legible marking on the rim, in an area not obscured by the tyre, (see also
6 z) and 5.1).

NOTE A symbol referring to the instruction manual is an acceptable marking for rims for
wear.

Where the rim is made of composite materials, the manufacturer shall include in the
manufacturer’s instructions warnings of the danger of rim failure caused by wear of

the braking surfaces.
