Disc rotor alignment

I have a "gravel" bike with disc brakes. I bought a second wheel set/tires and brake discs to have one set up for road and another for gravel. Here is my concern. The new discs sit approximate 1/16 of an inch (maybe 1/32) more inboard than the original discs such that it slightly contacts the inboard pad, regardless of which wheel I put it on. It is as if the disc needs a washer/spacer/shim between it and the wheel To keep it off the pad. As if the housing of the new discs are that little bit more narrow than the original.




Is this a big deal? Little deal? No deal at all? How much "gap" is appropriate between discs and pads?




The Wheel spins freely enough (a subjective evaluation) so maybe the friction (if any) is not an issue. I don't know. Should I just try to adjust the pads in caliper and push the pad away from the disc? If so, how?




Both sets of discs are Shimano 160s. Wheels are thru-axles. I torque to bike's specs.




Thanks for reading.
