28x10.5-etdrag tire pressure M6
#2
I started around 15psi cold and worked my way down. My best 60' to date is 1.62 and the tires were at 10psi cold. I think the rule of thumb is to keep lowering psi as long as your 60' is improving and you E.T. MPH isn't suffering.

I have always been told I am nuts, but I would run anywhere from 11.5 to 13 PSI cold.
You can work your way down until, you cup the tire and loose traction, or work your way up.
I prefer to work my way up. I start out with 11.5, and keep adding air untill I spin, then back down about .5PSI
