front wheel dish on disc wheel

the blur

so i just got a new set of mountian bike wheels built up, and mounting
them on the bike i noticed that the front wheel (which is disc) is not
centered in the fork. i guess this makes sense since the wheel would be
stronger if the spokes are the same angle, but will it ride funny to
have the wheel off center? do all disc wheels have this lateral
displacement? or are they usually dished so that the rim remains in the
center, to compensate for the rotor on one side?

I think you'd better take it back to where you got it.
Front wheels should be in the centre of the forks.If it is not central,
then your steering will be very strange.

Yes, it will ride funny if the rim isn't centered. No, properly built
wheels have the rim centered. Yes, they are dished to compensate for the
rotor on one side and the rim is centered.

The rim must be in the centre of the fork, but the hub flanges will not
be equidistant from the dropouts. Rear wheels on virtually [1] all
derailleur bikes are the same - have a look.

[1] I used to have a bike with a 5 speed freewheel and managed to build
a completely dishless rear wheel for it, based on a 6 speed hub with
different spacers.

Not correct!! Turn the wheel around and if it is offset the other way, the
wheel rim isn't centered between the hub axle flats. It is a version of a rear
wheel, with unequal tension on the spokes...but the rim should be centered!!!
