I think he's talking about the lateral offset from lip of rim to edge of tread, which looks to be a few inches.
I'm not seeing a difference anywhere near that large.
yeah the bulge is fine... i was always told to keep the edge of tread even with the edge of the rim.
Depends on the application. You get better grip and breakaway characteristics while cornering if you stretch the tire a bit over a wider wheel- just not exceeding the tire manufacturer's recommmendation though.
