I just put MT ET Street radials on my truck for the first time last week, so I'm still learning myself. I ended up at 22psi, did a second gear burnout at 6000rpm for about 3 seconds and let it coast out and hook. It made all 8 passes between 1.552 and 1.560 sixty foot. On the 40 mile drive home I noticed some vibration...after checking the balance I found that the wheels had turned about 4 inches in the tires! I guess it's either time for rim screws, or maybe a little more air pressure.
