I'm upgrading my wheels from the stock 15" steel wheels from the base model 850 to the 16" Aluminum 5 Spoke "Columbia" wheel. Do I need different lugs from those that came on the steel wheels. Upon inspection I can tell that the head of the bolt is much longer on the lug from the alloy wheel vs. the shorter head on the steel wheel's lug but I can't see any other difference. Just want to make sure the things that carry me at 70mph down a freeway don't spontaneously decide to fall off. Better to ask a dumb question than to make a dumb mistake!

(PS. Sorry for my *cough* "enthusiastic" number of posts as of late)

 

Steel bolts will work just fine but the taller bolts started shipping with the alloy wheels in '97 or so - the taller head is for better access on the allow wheels without covers (ie my 95 has the Cetus alloys with the cover. ) Check out part #3546899 for the nice chrome bolts - you can find them for $3-4 each (you'd need 20) at IPD, FCP etc.
