Wheel and Tyre Fitting Check List
Before fitting tyres on aftermarket
wheels check:
 |
1. that the stud/bolt hole
pattern is correct.
2. that the wheel fits freely onto the hub without
interference and that there are no screws, rivets
or retaining clips which may interfere with a firm,
flat location of the hub against the wheel mounting
face.
3. that the wheel rotates freely and truly on both
front and ear hubs
|
4. when fastened to the hub, that no part of the wheel can make
contact with the brake drums or calipers or any other part of
the steering or suspensionCheck nuts
and bolts. Correct fitting is vital. Be sure1. that
the thread form is correct (fit nuts without wheels).2. that
the nut/bolt seating is correct.3. that the stud length is adequate
for minimum thread penetration of approximately 1 x stud diameter
and not too long as to permit "bottoming" of the stud
in the nut.4. that the threads are rust free and not over-lubricated5.
when sleeve nuts are used, that the shank diameter is correct
and that the bearing washers are always used.When
fitting the tyre
| 1. make sure that the rim size is compatible
with tyre size.
2. be wary of scratching the protective lacquer coating
(on aluminium wheels and some chrome wheels). Aluminium
corrodes very easily once exposed to atmosphere, water
or chemicals.
3. where possible always use the adhesive type of
balance weight, as these help to avoid scratching
of the wheel finish.

 |
Finally Check
1. that the wheel and tyre assembly does not contact any
part of the suspension or body work by carrying out full 'bump'
and lock to lock tests before driving the vehicle away from
the fitting bay.Do not take risks.
Wheel security is vital. Check with experts if you have any
doubt.
