three nub are normally an indicator of pre-disk brake days, they may not fit because of the shape of the inside of the rim. Rotors aren't the issue, the inside of the taper between wheel center and rim rubs the caliper. 71+K wheels fit over STOCK calipers - so you'd need to find a stock skinny set of K5/10 wheels from 71 or newer. Since you have the 3 nubs, I'd still give it a try before mounting tires just like you mentioned - but 3 nubbers normally won't clear the caliper, sorry.
