Also that is why they use the shuttle (of which eyeball hates) to fix

Earth to fix as he implied with his (dumb) post.
The original intention was to return it to Earth one or more times for
equipment upgrades and general maintenance, but it ended up being to
heavy for the Shuttle to safely land with it.
The problem with theory is it's launched on the Shuttle, it's by
defintion light enough for the Shuttle to land with it. (RTLS, TAL,
AOA, some ATO scenarios...)
Not exactly.
The shuttle tires aren't used during launch; I'd bet that those are the
limiting factor on landing weight.
But they would be used in the case of all of the abort scenarios that Derek
outlined above (RTLS - Return To Launch Site (Just after booster
separation, turn back & land in Florida: TAL = Trans Atlantic Landing -land
in (obviously) Europe - usually Moron AB or Zaragoza AB in Spain, or one of
several sites in Africa: AOA = Abort Once Around - Not quite an orbit, land
in North America: and ATO - Abort to Orbit reach orbit, but not enough
speed for the desired orbit) In all cases, the end goal is to have the
Orbiter putting wheels to runway somewhere.
The limiting factor isn't usually weight, with airplane tires, but speed.
The tread section is pretty heavy, and the tire carcase needs to hold it on
while it's spinning at a zillion RPMs.
