Checklist
- Check Alloy Rims, especially Motocross for
corrosion underneath the tyre. Elongated nipple
holes caused by
loose spokes and cracks where the rim is "Buttwelded".
- Is The Wheel Really Buckled?
Check the tyre is correctly
seated on rim. Often when a wheel has been sitting on a flat tyre, that tyre
becomes misshapen and may stay that way even when re-inflated..giving the impression of a bent rim.
A "Rim-Tape" incorrectly fitted on the rim may sit under the tyre bead
preventing the tyre from seating correctly and giving the
impression of a buckled wheel.
The same applies for
incorrectly fitted "Rim Locks".
If unsure, deflate tyre. Use Tyre
Soap or Soap and Water around edges of tyre and
reinflate
checking that tyre "Pops Up" to correct
position.
Before refitting a tyre, check that spokes do not
protrude through nipple. File off flat if they do.
Truing
Rims are always trued to the register, i.e the
part of the rim where the tyre bead sits. Some
manufacturers rims
are often poorly produced so that whilst the register may be true
the outer edges of the rim may not be. This can be noticed when
spun. The tyre will be perfectly true, but the edge of the rim may
"Wander". Especially true of Alloy "Flanged Rims".
Motocross Wheels
Due to the hard treatment these rims
receive they often have "Flats" on the rim where they may have
contacted a tree root or another hard object. When spun, the "Flat"
on the rim itself is very obvious but the tyre bridges the "Flat"
and is often reasonably true.
Spokes usually break as a result of
becoming loose over a period of time and a few taking the strain.
Keep spokes, especially rears, tensioned up. Check this from
time to time. |
