35 spoke rim run out

[cas3]

Newc is on the right track, you never told us what drums you are using. If 35 on a 35, no spacer, just make sure nobody ground off the nubs that support the rims. To address the question, I've never seen a perfect wire wheel. an1/8 " run out is good, 3/16 put them on the back, more than that find a better wheel. They must be round, and check on the inside of the rim where the bead sits, not the outside edge
