Why wheels stickum?

[Chris Thorp]

I'll have to try this next time I change my wheels.  I bought my first 
Audi last August and decided to put snows on it for winter.  When I went 
to remove the wheels, I ended up *WAILING* on it with 5# hammer for 
about 10 minutes per corner to get them loose (with a 1.5cm thick parts 
catalog as padding to prevent damage to the rims).  I was really worried 
that I was doing something horribly wrong, as this was my first Audi 
experience.  Suffice to say that the catalog was toast after this 
exercise...  Here's to hoping that my snows come off without all the 
banging.
