Et street radials on a 4 speed ?

Are you street driving or hauling the car to Mason/75-80? With street use involved, I'd probably do the ET street your thinking of. If you're trailering to the track, a bias ply with tube is the way I'd go...

Not sure what size you're dealing with? Unless you're running a small tire that needs to be at a really low pressure, the slick/tube combo doesn't necessarily need to be pinned? imo. In my day, a well mounted bias tire of adequate size & pressure had no rim/spin issues on mid/high 11sec & slower cars, including some sticks.
