Scott you don’t need to run tubes. I have a set of 28 x11.50x15 et street r on my hemi Cuda.
I bought them from Larry Hodge racing tire. He is a full time racer and said I didn’t need them. The trick is to spray the rim with hairspray when mounting the tire. It glues the bead to the rim. I didn’t believe it but trusted him and it worked.
