Lug Nut and Wheel Covers

[Tikvah]

I'm getting ready to do some cleaning...

I have the wheel covers with the chrome lug nut covers.  The rings look good, but the lug nut caps are rusty.

How do I know what size lug nut caps?  33MM ?

Also, the round center of the wheel is always exposed.  Is there a cover for this?

Any suggestions of a good source?

Those are cool, but how do you know what size or type to get?

Dave, if you have stud pilot wheels they are 1-1/2 in if hub pilot wheels they are 33MM and I don't know of center cover if it did not come with your covers

Go to any big rig supply house and they'll have numerous sizes of lug nut covers.

I've seen numerous sizes, my question is "what size to do I need?"

Best I can tell those are 1-1/2 x 2 in I bought 60 from Amazon for 30 bucks (Metal) not plastic,buy the ones with the flange then they cover the space I see around yours

Most of the truck stops in this area stock an assortment of lug nut covers and hubcaps .Exit 15 on I 26 is a good one .Even camping world stocks some Lug Nut covers.Don't know about the center caps.Might be a good idea to dress the wheels up and forget the wheel covers.I have never used any of these things that were not noisy .I have tried every fix imaginable and none of them has ever worked !!

The hub piloted wheel nuts ( http://buytruckwheels.com/media/catalog/site/Hub-Pilot.jpg  )  have an integral washer on them where they contact the rim while the stud piloted wheels ( http://buytruckwheels.com/media/catalog/site/Stud-Pilot.jpg ) have a ball face (rounded) contact area. The hub piloted wheel nuts are 33MM and the stud piloted are 1-1/2"

They had a cap that slipped under the main cover and one with a hole in center for oil hubs.Some had the cover integralThe rear covers looked convex like the fronts and used aluminum pipes threaded onto rear stud remaining threads to mount.You then threaded nylon lugnuts on the outer threads of the pipes and then pushed on thin chrome lug nut covers.They may have made rear concave ones also. I always thought the rear ones were a pita to take on and off. Chromed steel wheels would be nicer, but around here the only place that chromes anything only does show chrome at insane prices.

So some MCI buses have stud pilot wheels and some have hub pilot wheels? 
If I ever buy a replacement steel wheel I need to know the lug nut that held it on?

Dave, it easy to tell look at the drive axle if the part the nut is screwed on to has a square head it is a stud pilot system

LOL, okay luvrbus, "part the nut is screwed on to..." 
What the heck are you talking about?

Do you do that on purpose?

YEP  surely in the 5+ years you have owned the bus you have seen the wheels removed from the rear axle the inner nut (inside dual) has a square head, the outer wheel takes a regular nut that screws on that nut, same size as the tag and front axle then you have a stud pilot system.
