Wheels: going from steel to aluminum

Here's my question: Steel wheels are usually thinner, so if you change to a aluminum wheels can there be a stud length problem? It looks like I've went from the lugs being threaded onto a stud about a half inch long to one being about a quarter inch long and I'm just wondering if there's a minimum recommended length for studs.

I have this imagine of all of the studs breaking at the same time on the freeway.... Ouch.

Thanks

What actually counts is the lug nut itself. No matter how long the stud , as long as the nut screws on it's full thread.

You want thread engagement at least as long as the bolt (stud) diameter.

The MOST important thin is making sure you have the right lugnuts for the wheels. There are various different styles available such as: conical, acorn, and round.

...so a quarter inch diameter bolt should go into the lug at least a quarter inch.

And I know what you mean about the lugnut and wheel being compatable.

thanks.

Most lugs are more like a half inch diameter. Also be sure to check the hub clearance; sometimes when running rims from a different make, the center bore will not fit, even though the bolt circle does. When attempting to fit Celica rims on my Neon, I found I had to overbore the rim's center by ~2mm to get them to clear the hub.

In reply to NYG95GA:

True dat. I'll check that when I get home (and it's daylight!).
