I use to mark my radial drag tires tires with a small dab of shoe polish on the tire by the tire stem, once it moved a inch or two I would swap the rims from side to side to move them back Most of them would take a set after swapping sides several times and not move anymore I was running 18+ Lbs. also with no glue or rim screws either, 3450 Lbs. running mid to low 1.40 sixty foot times I had to add rim screws on the bias tires though
This is exactly what I did. I switched to radials and had the same issue with the tires spinning on the rim, well one tire. Cab gave me the same advise and it worked as described.
