Which shortcuts should be in our library and which not?

[Magnus Forsberg]

I would find the presence of the simple wheel+tyre assemblies more helpful.
Doing that avoids all the hassle of
- having to define a new syntax
- adjust all the parsers
- make people understand how that is intended to work

It wouldn't need a new meta/syntax just a keyword which is present in both a tyre and any of its matching wheels.

That is already present in all of the tyres and rims following the naming nomenclature.
The rim diameter is a common denominator.
