Stick On Alloy Wheel Weights - WTF!
Just noticed something hanging down off the inside of one of my new alloys. Turns out it's a sort of 'stick-on' balancing weight
that's become un-stuck!
Not really noticed them before, but a quick checks shows all my alloys have them. They're attached with a sort of rubberised stiky-pad.
I've not used the car yet, it's still being built yet these weights are coming off already! Dread to think what would happen once
I'm on the road and travelling at speed - don't fancy a lump of lead hitting me in the head 
Anyone else had experience with these things? Should I just remove them all and get the wheels re-balanced with the proper clip-on weights? Seem
really dodgy to me?

They use stick ons, because clip ons look ghastly on alloy wheels and spoil the look. If the wheel's cleaned properly they should stay stuck.

That's the thing. The alloys have never been cleaned - they are unused?
There are also some normal clip on weights, but attached to the inside rim.
To be honest, I think I'd rather have them a little ugly than deadly.

Yep one of mine fell of on the way home from having them done.
And that was sat in the boot of my tintop.
They where fresh from the powder coaters so they where very clean.

DO NOT USE CLIP ON WEIGHTS
They corrode your wheel behind the clip, always use stick on weights i have never had them come off

When I fitted new tyres I had the mother of all jobs getting the old stick on weights off - along with the glue marks 
I've never had one come off un-assisted , even on a 170mph drag-bike 
Its cuz I is blond , innit

Clip on weights fall off randomly too...
Stick should be used with alloys. Also, as the alloys are generally wider they can get the weight in the right part of the wheel rather than trying to
make it work from the very outside edge.

Not pretty bad it isn't a bad idea to stick some metal tape over them to prevent them parting company with the wheel.

If you accidently get your finger(s) jammed between the stick-on weights and the steering arm when spinning the wheel.... you'll know why
I'm not a fan of them. All mine have just come off in the past, gaffer tape over them does help.

Thanks for the replies all.
Seems to me not to be a very good solution from an engineering point of view, but it looks like it's the only option 
As suggested, I'll be taping over them to give me some piece of mind.

If the weights haven't been pre-formed to the rim curvature then they either only stick on the outer edges, or only in the middle. Made worse
by having to use Zinc ones now - about 30% bigger than the old Lead ones and don't bend to the rim as easily. They work fine if done right. If
they have been applied been applied recently and ARE Lead, then they're old stock and the sticky bit will have gone off..Zinc ones have a little
"Zn" mark on them, usually next to the weight (in grams)
The rim does need to be pretty clean for them to stick properly though. New ones out of the box would be fine, but if someone's been out with
the silicone spray...
Long live RWD...

I've fitted thousands of stick on wieghts. I'd not had any come off even on the grottiest of rims (my customers would be back complaining
of a vibration) untill I balenced my brand new Compomotives. I always wipe the rim with brake cleaner but because these were new I didn't and
they peeled off. There must be something on the surface of new rims (they look clean) because once cleaned the wieghts stuck like the proverbial.

The old hammer on weights are the very last thing you want on a nice new set of alloys. The spring clip gouges off all the lacquer and then
bi-metallic corrosion starts forming.

I've got stick on weights on all my race wheels and find regular use, bit of the old silver masking tape and centrifugal force, helps keep them
in place.
