Mickey Thompson Drag Radial Tire Pressure Poll

Mickey Thompson Drag Radial Tire Pressure Poll Wanted to get some info of what pressure is working best on an average in these. I have tried all different pressures and can't get the results I want. With slicks it was so much easier!

I'm running MT ET Street DR's on my datsun puny little 235/60/15's and run them 17-19psi but i've only raced on them a few times honestly and my 60' are near as good as yours.
i cut a 1.77 as my best but the ET was 11.77 @119.9X

You will see some variance by tires size as mentioned above. And, from different tire guages. I voted 14-16 psi, that is what my car likes. I run 275/60-15's on 15X8 Weld Pro Stars. My car has gone a best of a 1.504 sixty foot. 1.51 - 1.53 is average for my car. It weighs 3540 lbs w/o a driver, I'm sure vehicle weight has an effect too.

What's your suspension setup to go 1.29?
26" tall on 10" rims. I think they are 255/50-15's for me.
I'm in a pickle. I have the adjustable TA that come with my MWC 9" set at -3. I have a UMI adjustable PHB and UMI lowers in the back with Bilstein shocks and BMR 1" lowering springs. Today I pulled the front sway-bar out which made a decent difference in front transfer. I have 1" BMR springs in front and Bilstein shocks. I didn't care for the 4x4 look so it needs to stay lowered. Question is what can I do to get dead hook? I have a ton on tap right out of the hole. If I could get it all to the ground launching hard it will go 1.50's pretty easy I think. I should be able to get 11.7's bolt-ons but need that hook! And don't know what to try next

I voted for two, 14-16 and 17-19. I normally run mine on 15-16psi, thats with 275/40/17 Mt drag radials with a best 60ft of 1.57. My mt drag radials 275/60/15 seem to like 17-18psi, best 60ft of 1.58. I was only able to test the 275/60 out once; rear, trans and converter broke that day.....
.......I'm sure I could have got a little better 60ft with them.

The guys I know that are going fast on the 275/60/15 are running around 19.
Get into the 295 and they like around 16, 315/60 like about 14, 325/50 are about 18, not sure on the other suzes, as these are the ones that are on race cars I know of first hand.

Less rolling resistance, better times. Sometimes when you spin, people assume to drop the pressure. You may already be too low and cupping a radial tire (not the same as a slick), so sometimes making 2 or more runs at a certain pressure is needed to verify the results (not being in the groove, too small or too big burnout, etc).

i use to run 16psi in them then i tried going as high as possible and 18psi seemed to be the optimum pressure. 20psi worked well until the track got real cold later in the night. so now i run 18psi
