M/T #3066R 30x9-15 Radials, 17-18psi. I've run 21+ in them like a lot of people, but that can bite you on a marginal track. At the lower pressure, they won't spin unless there is physically something on the track, or the chords have been hanging out of them for awhile.
No glue, no tubes, no screws.
Been 1.37 60' "on kill" at 3,335# in perfect conditions. Typically 1.44-1.46 at 3400# in bracket mode. I run these tires full time, even bracket racing.
