Need some help. What p.s.i. Are you guys running in your drag radials? I am running 275/55/16 m&h racemasters, truck tips the scales at 4500, has 3:73 g80. I have been running them at 25lbs and the hook fine for 14.7 pass, but the 2 times i hit the n2o they just go up in smoke. I know these tires will hold for high 12 pass because i have seen them do it on my buddies old truck. But he has absolutely no recollection of the p.s.i. He was running.
04 ecsb 5.3- perfectly tuned by Nelson perfomance, Pacesetter longtubes, 100 shot n2o from NX, cold air intake.
03 rcsb charbroiled (race truck eventually)

Idk about the M&H but my M/T's like 13lbs. I spin them at 18lbs.
I'm running exact tire at 22lbs on the street tho. And it's a huge diff from 25 travtion wise. Iv been down to 16 with success
Slowest in Oklahoma...
never had luck with a DR that low on psi, alway liked them up around 18-22 psi. if i had spinning issues i made adjustments to suspension or launch technique

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
ive seen a 235 radial go low 9s.... just cause someone else has done something on a certain tire doesnt mean you can. so since the tire is capable and its still not happening that points towards the suspension. you cant always just bolt on some sticky tires and expect miracles to happen. it takes more than that
01 Silverado
16-18psi
well these are actualy my friends tires that he ran the 12s on and we both have the same truck and rear suspension (2in shackels) differences i have 2in drop springs in the front. and his was a 5.3 turbo mine is 5.3 n2o

n20 hits differently then a turbo setup off the line
still every vehicle is different, you cant compare his setup to yours
