Quote: I run 9 x 28 M/T's with tubes on an 8 inch rim with 18 lbs of air. They aren't screwed to the rims. Been doing this for the past 6 seasons without any issues. The tubes keep the tire stiffer at launch and all the way down the track.
This is dangerous right here. If the tire ever happens to slip on the wheel, it will likely rip the stem out of the tube and you will be in for a rough ride, straight into the wall. I understand you have done it for 6 years. But all it takes is once.
Personally, I think people are nuts, not to anchor the tire to the rim in some way, but thats just me. Last year at an ADRL race, I saw a driver get after an XTF car too hard in the water and knocked both rear tires off the beads. Thats how fast it can happen

I really don't know what these guys are thinking. Maybe they just haven't seen this stuff happen themselves.
