Screw in place
Using self-tapping 12mm * 3.5mm screws (countersunk head). Using worn Bontrager ACX 29er as a base there was no need to drill guide holes, the rubber is soft enough to just screw into. 70 knobs around the circumference, put a screw in alternate knobs on two of the 6 sets across the tyre. A bit worried that they might not be central enough to aid traction. Applied superglue to Screwheads after insertion, as others said this was a good idea, not sure if that will be required.
(Gunk on tyre is from previous tubeless setup - planning on using tubes in this case.)
