take tie wire:

attach to rim:

attach to cap:

reattach cap:

now hopefully i will be alerted by the noise they make instead of falling off.
what say ye?
i put a coat of plasti-dip to help with at least 3 mpg.

It would be really bad to have a cover loosen at speed,in traffic,where you couldn't immediately get over to secure it,and then have it sling around on an unbroken safety wire,hammering the car until you could burn off speed,or get launched like a discus into an unwary motorist.

remove the wire and it's gonna fall off eventually. had to tap the front on the other day because it worked loose on one edge. lost 2 already and have no idea where they went.
there is just enough slack in the wire to access the valve. my speeds are 55 right now.
it is a concern of mine though and had the idea to use a couple of small diameter bungee cords to replace the wire. tension would be tighter allowing them to stay in place but not be slung around.
if you have a better idea i am all ears. i do want to be safe.
*EDIT* learned something about Photobucket. even if you just change the name of an album, it will not link photos.
i also bought some bungies so i will be replacing the wire soon.

It's on a list now, but first I have to find them.

It's more likely I'll have a sheet metal shop punch out 24ea 1" disks, rather than have you ship material from TX. Thanks though.

Short of going to the weld-on Dzus fastener system,an adapter might be fabricated which was captured under the lug nuts which provided a hard attachment point(s) for the MOONs.Even a single central fastener might prevent the cover from beginning to displace outward.Don't know.

(1)Dzus wouldn't work. these are stainless with the attachment crimped to the underside. holes would need to be punched through the stainless after removing the attachment device.
(2)thought about this also. welded nut to middle of rim with some way of centering it. a round head long thread stainless screw mounted with blue locktite........
sounds complicated....
i don't know either, reason i went with wire. next will be elastic cords.

This was my first concern, but it looks like if the wire ties are kept short, there's no risk of a disk contacting the vehicle body. I'm going to do this or something similar as a precaution/ anti theft measure, my genuine Moon's seem fine as is though.

Bungee cords seem like a good idea, but not sure how much tension you can get on them (seems like they might be tricky to install. If they do work, you might also have another way of securing pizza pan discs too (3-5 L brackets to locate the disc to the rim, and a pair of bungees to hold the disc to the rim face).

The movie that I played inside my head depicted all but one wire shearing,and before the last one let go,that the disc would be accelerated into the body or launched in any direction when the last wire snapped loose.
If it shot rewards it could shatter the windshield of a following vehicle,rendering them momentarily blind.Potentially disastrous!

appreciate your concern and will be using elastics next

Bear in mind that a 10mm steel chain has a 1 tonne breaking strength. Even fairly thin wire can support a couple hundred pounds (the wire used by deejaaa looks a little on the thin side, admittedly).

Now a 10mm multistrand steel cable is capable of supporting 10 tonnes. Even the smallest steel cables in the 2-3mm range would be well over kill for preventing flyaways. Stainless cable is available from the hardware store along with all sorts of crimp ends and quick release connectors. I can imagine very short cables with quick connectors being a fool proof way to go.

My goals are a little different, since I don't expect my covers to ever let go I can be a little more gun ho in my approach. On a wheel/ disc combo that's proven to shed discs regularly, you'd want to think it through properly

My concern here is that repeated rubbing against the fairly sharp wheel window edges will still cause a failure. Duck tape any where they might rub.

My second concern is how they'll hold up to the repeated hot/ cold cycling effects of the brake discs. Constant temperature cycling will cause rubber to harden, loose it's elasticity and perish (particularly if the rubber wasn't intended for temperature cycling). You could consider making your own elastic straps from motorcycle inner tube, that material is at least designed to withstand some decent temperature cycles.

I will probably use the elastic idea on my trailer wheels, there's not much heat cycling (no brakes) and the backs to the wheels are easy to access to tighten/ attach the straps.
