Tragedy

HGV wheels under loads have a tendency to loosen wheel nuts on the near
side (I think) and hence have left handed threads on that side.
Sometime a right handed hub gets put on by mistake or negligence and if
left unchecked then the wheel can come off, especially if there are two
wheels on the one hub as it can happen without the driver noticing
anything amiss.

But MOT or no MOT, it woukd not have made any difference ... whilst loose
wheel nuts will cause an MOT failure, it is a fact of life that wheels are
removed from time to time for routine maintenance, and then replaced, and in
an ideal world, re-torqued after a short period. It is *there* that the
seeds of "loose wheel nuts" are sown.

Or not torqued or even done up in the first place as happened at the
local car depot with my car

So shocking that nobody's questioned the description "freak

accident, it's an all-too-common result of not checking the wheel nuts.

Is this a confession?

Er, I've never had a wheel actually come off.

There are many scenarios in which a wheel can come off an HGV, loose

bearing failure.. fire and wheel exit.
Mind you I have never seen this but I have heard of it. And in a road
train one might miss the fire.. it could be a long way back.

Wheel failure. Now this I have never heard of in a HGV but it must happen.

There you are, 2. Both really unlikely

Knocked off during an accident? 3

I've certainly seen the entire tread come off a remould truck tyre in one
piece at speed, and it was certainly quite heavy enough to kill a
cyclist.

I've seen the entire tread come off an HGV tyre. The tyre in question
was about five metres ahead of me, one lane to the left, and doing
about 65 mph. It was one of teh hairier moments I've had while
driving.

I don't remember the exact figures but every time the provincial police
here do a large truck safety check (HGV?) we have about 20-25% fail
with many being immediately towed, not driven, away. I hope inspections
are better in the UK 🙁

Nope. Sounds much like the buses round here:

About 5 years ago a bus crashed into a barrier at Bristol bus station
when its brakes failed, making the national news (I can't remember
whether anyone has killed, I have a feeling that someone waiting behind
the barrier may have been). My wife had been on the same bus earlier
that morning.

I once walked a few miles alongside a fast dual carriageway, and was
very disturbed by the number of large slabs of tyre rubber that
littered the grass verge.

half shaft failure (semi floating axle), hub carrier failure, bearing
failure, bearing stub failure, wheel centre failure, not fitting central
split pin, can all lead to a speeding projectile with wheelnuts nice and
tight.

Thanks.

Though I'd say "freak accident" should be saved for the sort of scenario
where a wheel falls off a vehicle on an overbridge, lands on top of a
lorry underneath, lodges there for 200 miles *then* falls off and hits
the cyclist.
A materials failure like the half shaft might be hard to prevent, but it
isn't a freak.

Bicycle helmets are really a bit of a scam.
They make most cyclists slightly less safe but there's money in selling them.
