i want to know as well...

 

What are they?

 

are this the ring trim you are taling about?
if they are,the answer is they just snap on the stock rim.
the valve stem will be sticking out and as for gas mileage difference I don't think it will make a difference as it doesn't add or take of weight.hope this is enough info for you...

 

I assume you're talking full disks, not trim rings.

Yes, they just go on your stock steel wheels. You pound them on with your fist or a rubber mallet. Never mind the creaking, boinging and scraping noises. This is how things were done back in the manly age before plastic hubcaps.

There should be an obvious notch for valve stem clearance in the prongs that hold the disks on. Line the notch up before you start pounding in the disks. Hold one edge of the disk firmly in place and work your way around, pounding in a little at a time until it's seated all the way around.

The valve stem will be completely covered. You'll have to remove the disks to check/add air. Pry them of a little at a time, working your way around. Be prepared to catch them if you don't want to scrape/dent them on the pavement.

Any difference in gas mileage will be unnoticeable.

 

 

 

 

I got the JC Whitney baby moon full wheel covers. Advice on here is correct regarding the install. I also got the valve stem extensions, so I don't have to remove the wheel cover to check/add air. Anyway, line up the hole in the wheel cover with the valve stem, and I put my knee gently against an edge of the wheel cover to hold it in place while I start lightly rapping the palm of my hand against the outer edge of wheel cover, and work my way around. Picture putting the lid back on a paint can, and you'l get the general idea. The clips run all the way around the inside of the wheel cover, so they're on there pretty securely.

 

 

hell ya! thats a lot coller than i thought they would be!

 

I miss the old days when someone would not put them on right and you would see one come flying off on the highway.

These look like they would grip well. Lets see some picks when they are on.

 

Socalxb, I like your setup, please post some pics.

 

Hey! I have baby moons on mine too... great minds think alike...

Check out page 2 on my car domain page, there's pics in there:

I like the look for winter, but ready to go back to my 18s, soon!

 

Both sets of wheels look great. I like the old school look of the moon caps.

 

Mine are, but I have Moon Eyes clear powdercoated aluminum disks with stainless steel prongs. Don't know if that makes a difference. Tolerances and prong tension might vary from brand to brand. In my case, to get them off I need to start with a screw driver, because a tire iron is too blunt to get in the crack between the disk and wheel. It takes some finesse, patience and a good bit of force to work them off without messing up the disks -- aluminum is soft). About once a week I go around the car checking to make sure they're on snugly. Haven't found a problem yet.

Here's a couple of pics of the baby moon full wheel covers I'm using now:

As for removing them, I have a "special" tool that I use. It's one of those screwdriver combo tools that has a Phillips head on one end and a blade on the other, at opposite angles to each other (picture an "L" shaped tool with another leg at the top going in the opposite direction). I insert the blade part of this tool inside the hole, and gently pull back. The gap is too small between the wheel cover and wheel to press something in between them.

 

I just bought a set of these off of eBay yesterday. The same seller has a bunch of them. Buy it now is something like $55.00 + 12.95 to ship. We'll see how nice these are when they arrive next week.
