[s-cars] Larger Tires and Rims

At some point you might have problems getting heat into a really large
tire with a certain compound.  I guess if you couldn't find a compound
that was soft enough you could run into problems with this.  On the
track the tire size is usually dictated by the class that you run.  The
approach that I have seen taken in almost all racing, except maybe rally
in the snow and dirt, is to use the largest softest compound that you
can get away with.  I guess if we worry about having a ruff ride on the
street while still having enough spring on the track then you might want
to stay with a smaller less aggressive tire.  I think a 400# car would
do well with some larger tires, apparently MTM thought so to.

Isn't there a point of diminishing returns?

Is there an *ideal* tire size for our chassis?
