Spare
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)
Eccentricity:
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 information column)
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
2. An excessively distorted or eccentric bead rim. (see information column).
3.
a. loose or missing wheel nuts, studs or bolts
b. an insecure wheel.
