Are the threads deep enough in the nuts? Might be the studs reaching the end of the threads before clamping the wheel down.

I'd be highly surprised if the wheels are hanging up on the register.

Easy to check, wheel off, hand tighten a nut onto a stud and measure the space between the seat of the nut and the wheel hub. It MUST BE LESS than the thickness of the wheel and washer.
