Im happy that i was not the only one who purchased the trx rims without the nuts. You can try this which worked for me. I ground down mag wheel washers to fit into the rim where the nut sits.(2 pre hole) and then i used mag wheel nut which had a longer tube which went through the washers and into the rim. The nuts did not have a taper like the genuine ones, instead they were flat and they seated on the washers. This took a while to make the washers fit into the rim but it worked well for the 5 years that the rims were on the car. hope this helps.
