 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 suspension
Check nuts and bolts. Correct fitting is vital.
Be sure
1. 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-lubricated
5. 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. |
