Tubeless road tires.

4. I've been hearing mixed results.

It seems to me that running Stan's sealant should help. On the tubeless tires I have read wear riders unmounting tires have seen little blobs where the sealant sealed punctures they never knew they had. Tubeless for road are fairly recent. The MTB people have been running them for years. It's taken the tire people a while to work out the higher pressures of road tires. Tubeless ready tires tend to have a higher tpi (threads per inch) then tube tires.

The wheels I use are already tubeless ready. There are no holes for the spokes. In fact I never used rim tape with tube tires on them. I did change out the stock tubeless valve stems for Stan's because the Shimanos don't let you remove the valve core. It is much easier to inject the sealant in a valveless core. Otherwise you have to squirt it in the tire before seating the bead.
