Factory Aluminum Alcoa Wheels

For single wheels. What size lug are the nuts supposed to be, 1 1/16 or 7/8?

 

[compressionignitionrules]

all were 7/8. the 1 1/16 were not in use anymore when these wheels came out.

Thats what I thought but they look wrong. They sit deep in the tapered seat. Just wanted to be certain. I have looked at some trucks and they all had 7/8" lugs also. Thanks.

the "correct" lugnuts have a "mushroomed" or oversized conefor centering the rim and a smaller shank area for slimmer sockets.

So Are they the same as the steel wheel lug nut? Do you have a picture and part number?

My 1993 SRW F350 had and still has tapered nuts [without washer] 7/8" on 9/16"-18 studs. I happen to be getting ready to order new ones that are black vs. chrome to go with my new blacked out wheels.

I'm not in the office this week, so I don't have my p/n's handy.
here is a pic of what the proper aftermarket lug nut should look like. the oem one is the same except the stud opening is exposed.
