Then you could use a light flexible plastic dish. Then you could even make them dished if you want, and then you can fit them over most aluminum wheels, which would be ideal. Weight savings and aerodynamics.

Maybe I should rush to the patent office.....



Not only that, but I can give you three more good reasons to use those on heavy duty trucks instead of the solid metal ones.

Those leave a window so you don't have to remove your hubcap for inspections. A lot of trucks use hub odometers or have indicators on the hubs for axle oil level.

Solid metal hubcaps scratch aluminum wheels.

Aluminum wheels save you almost 200 lbs of weight per axle, and in the trucking industry, little savings add up. So, again, why put metal hubcaps on and add to the weight, since most of the reason for the metal hubcaps is to make those steel wheels tolerable to look at. Those little plastic things weigh under a pound versus 4 lbs for metal "moonie" hubcaps. 8 axles on truck and trailer not including the steering axle, two hubcaps per axle, that is 100 lbs more of unwanted weight that could have been cargo or fuel savings.
Those style caps/covers are widely used in the dirt racing world here in the US., but for a different reason. On dirt, they keep clay clods/buildup from getting lodged within the rim. They're fabbed out of aluminum, and weigh well under a pound. They're easy to attach as well. Takes about 20 seconds and one screw.

Bingo! At 3-6mpg, an increase of 1-5% saves an owner operator (or company) a sizable sum in any given year. Its the same reason sail panels and the fold out tail fins are going on lots of trailers these days. Create a more efficient passage through the air (less drag), and those things pay for themselves pretty quickly. It all adds up, especially when you're buying a 100-150 gallons of diesel on a fill-up.

This is relevant to my interests! Got a link?

I did a search but what I found was for bead lock wheels.

If you look at pictures of Charles Lindbergh's airplane, the "Spirit of St Louis," you will note the wheel covers. They were made of cloth, and were literally sewn onto the sidewalls of the tires.

Just attach these to your stock hub caps (just make sure you don't put your wheels out of balance) http://www.webstaurantstore.com/16-a...m/407TP16.html

Easier said than done. I bought a set a couple years ago, clear-coated them, and even modeled them to see what they'd look like.


They fit my wheels perfectly, though they are horrifically ugly with that blackwall...I should model one with a whitewall.

Anyway, the hard part is attaching them. I figure maybe I could glue/bolt them to a cheap set of whatever wheelcovers, but their retention systems tend to be barely sufficient without the extra weight of pizza pans. In the 1980s some GMs with wire wheelcovers came with a bracket that attaches with the lug studs and adapting that system would probably be best.

Ohhh, pretty.

They say steel wheels, but I don't think they mean stealies. Aero's racing wheels look like aluminum, but are actually steel. SO these might fit any type of wheel.
