Stud length with Aluminum wheels?

[jaredg]

I just bought a set of Vision Raptor wheels in 17x8 size, +25 offset. I was test fitting them in the garage to test for clearances, etc and found that the lug nuts only engage about 4 to 4-1/2 turns by hand. That doesn't seem like nearly enough thread engagement. I've always gone by the rule of thumb that you want at least as much engagement as the diameter of the stud. That would be about 9.3 turns for 14mm x 1.5 studs like we have. I only have about 1/2 of that.

 

Has anyone else run into this problem? If so, what did you do?

Hmmm, no, my aluminum wheels allowed plenty of engagement. Wierd....?

Andy - Do you know what type of lugs are on your wheels?

 

I just found the ones pictured below over the weekend. Mine don't have the .25" straight section at the bottom. That might make the difference if they will work with my wheels.

I'm gone for work this week, but I'll pull one off and check when I get home. I don't believe my lugnuts have that bottom collar either, but maybe that my wheel is just thinner at the hub?

Andy - I am interested to hear what you find later.

 

I called the retailer today and they said I need the extended thread lugs pictured above. They were not in stock, so it will probably be a week or so before I get them. Then I will be out of town

Update - I got a set of the extended thread lugs pictured above and that got me the extra thread engagement I needed. It also has the added benefit of locating the wheel on the hub pretty well since hub rings don't seem to be offered on a lot of these applications.

Did the center cap for with these lug nuts

Oh yeah. They work fine with the center caps.
