wheels are not included in the inspection, but if a defect
is seen the owner should be advised.
In considering whether the original strength of a wheel
has been significantly reduced the tester must decide if
the wheel is rendered unsafe.
The maximum allowable rim distortion limits are as follows
Lateral (ie run out or buckling)
(a) For steel rims 4mm
(b) For aluminium alloy rims 2mm (cast or fabricated)
(a) For all types of rim 3mm
Measurements should be taken from a machined surface in
the case of cast aluminium alloy rims.
This inspection also applies to the wheel
attached to the side car.
Particular attention should be paid when assessing stainless
steel spokes for cracks
| 1. Examine the condition of the wheels, (see
2. Spin the wheels and look for buckling and eccentricity.
3. Check the security of the wheels.
| 1.a. deliberate modification,
inadequate repair, excessive corrosion, damage or fracture
of a road wheel which significantly reduces the original
strength (see information column)
b. a spoke which is missing, cracked, excessively loose
bent or corroded.
c. loose or missing rivets or bolts in built-up wheels
2. An excessively distorted or eccentric bead rim. (see
a. loose or missing wheel nuts, studs or bolts
b. an insecure wheel.
