First just thought I'd share an experience with others so that some may benefit from this possible solution...

We have an (almost) 1 owner very original 84 Firebird, 2.8V6, F41 suspension. For over a decade balancing a few of the
rims has been problematic sometimes yielding wildly out of balance results that might be resolved in a few tries. Or
not. These are the factory original steel rims, 16 slot 'Rally' wheels, 14X7 (P205/70R14s). The center cutout is NOT
round - it has 'tabs' in it that the tire balancing machine cinches up to. We've been thinking it's a bent rim however
what has apparently been bent on a few of the wheels are those 'tabs' which of course may (depending on how they put the
wheel on the machine) causes the darn think to be off center. The solution is to be wary of the tabs and ensure they are
at least relatively straight. The ultimate solution might be to ensure they are balanced on a machine that bolts the
wheel on rather than clamping it on w/ one of those cone shaped things. Turns out to be a an easily overlooked problem
for a problem that has plagued us for a couple sets of tires now.

Question: What is the BOLT PATTERN and OFFSET for 1984 14X7 Pontiac rally wheels (P205/70R14)?
