Tire pressure on street radials 4 1/8 mile?

Actually, cometbfx, I race in a radial tire class, & have raced in a class where even drag radials weren't allowed. IMHO, an aired down radial is more stable than an aired down bias ply slick or cheater slick. You air those down to the 10 psi range to race at the track for optimal traction. That's seems even scarier to me!
My 275/60/15 BFG drag radials at 12psi still felt stable at 128.61 mph (which is what I ran this past Saturday testing!)
