Bias ply slicks vs drag radials

You driving to the track, as opposed to trailering, run the Drag Radials, trailering run the slicks.

So I last raced 32 years ago when there were only slicks. Retired a few years ago, put a modest car together, that I drive to the track, so I got the radials, MT & then M&H. Both working pretty well, but found I spun the rim on the tire at 15psi last runs.

Never had that problem with the race only car as the rims were screwed since I only ran 4psi. Broke down the new radials and Scotch brighted the tire beads and rims with alcohol, so we'll see in couple weeks at the next race. My conclusion is the radial tires are sticking, ... and that's good.
They are supposed to dead hook at the track, that is in their design, whereas a slick is fastest when there is a little bit of controlled spin. I personally have only used the M/T drag radials for street and strip use.....never had a treaded tire on the Barracuda
