bah. yeah, sorry, I always get that backwards.

Still, though, +40 on an 8" is not as bad as +45 on an 8.5" .... i think.

An 8" wheel is 203.2 mm wide. So a +40 would put the mounting service at 61.6 mm from the outer wheel face. Meaning 61.6 mm is sticking out from the hub.

And 8.5" at +45 means 62.95 mm is sticking out from the hub. Is that right?
