Re: Is it necessary to balance Delorean wheels *on* the car?

On most premium branded tires there is an index mark on the tire that
the person mounting the tire to the rim is supposed to line up with
the tire valve. Doing this reduces the amount of weight needed to
properly balance the tire. You can balance the tire without lining up
the mark but the less weight you use the better because of what is
known as "Unsprung Weight" (look it up) It doesn't make a whole lot of
difference usually on a tire but the faster you go the more important
it gets. Also on the really high performance tires in many cases with
high speed ratings you can only mount them and use them to rotate in a
particular direction because of the extreme centrifical loads. They
are made to only turn in the direction of an arrow molded in the
sidewall. For a lot more technical information if you go to the
websites of the major tire manufacuteres they have a lot of info. BTW
I try to stay away from the wheel weights that glue on. I have seen
too many cases where they fall off and then the tire is out of
balance. I also see many times where an owner didn't like the way the
weights looked so he had them all put on the inside of the rim. This
defeats most of the purpose of having a wheel dynamically (spin)
balanced. Any time you have a wheel mounted or a leak repaired you
should have the tire rebalanced. Make sure they remove ALL of the
weights before trying to balance the tire and always use new ones
(when reusing weights they can fall off easier). Good advice for all
the cars you drive.

when you do that, you take into account imperfections in the wheel hub
and other suspension parts. since the valve stem isn't equidistant in
four places on the wheel (making good balance), you have to remember
where the stem goes in order to return it to proper balance. the
difference is small, but it is the best. it is called a 'dynamic
balance'.
