I'm going to be upgrading to Alcoa wheels sometime during the
next few months. There seems to be a difference in opinion from
some folks regarding the need to replace the wheel studs when going
to Aloca wheels.

Cinnabar and it seems Jim Bounds recommend getting new studs.
Others tell me not to bother.

What is the reason replacing the studs? Should I replace my studs
when I go to the Alcoa wheels?

My studs are 1/10 inch below the end of the nut with the Alcoa wheels. The threads on the Alcoa nut
end at about the same place. The engineer at Alcoa said they recommended a 'stand-off' of 1.7
inches, but when pressed said that a minimum of 2 threads above the nut was OK. I presume he meant
above the threaded portion of the nut.

New studs cost $1.69 Canadian, that is cheap insurance considering I do not know what kind of abuse
the original studs were subjected to. I need to pull all the wheels and hubs to check bearings etc.
anyway.

Richard,
When I put one of my new Alcoa rims on a rear brake drum/ hub assembly with OEM
studs and using the Alcoa nuts to test if the studs were long enough, there
weren't any threads showing above the nut. The end of the studs looked to be one
or two threads short of being flush with the last threads in the nuts. However,
when I did the same on one of the front hubs I had recently removed and replaced
with new ones, there were about two threads showing. So I might have been able to
get by without replacing the studs on the front hubs, but definitely not on the
rears. You might find different results with the studs on your hubs depending on
if they are OEM and or have been stretched by over torquing. I plan to replace my
rear studs with longer bolts. My new front hubs (came from Cinnabar) had the
longer bolts already installed. Good luck with your Alocas.

There is always a difference of opinion when it comes to spending money.
After many years of wrenching on and off the studs stretch over time.
Also, the Alcoas will require a little reach. The important thing is to
get the special nuts with swivel washers as regular nuts will chew up
your nice new, expensive wheels.
