Drag Racing Tech - What psi works the best for Nitto DRs??

I am currently running 18 psi cold and it gave me a 1.81 60'.

Then I dropped it to 17.5 warm (from 19.5 after the run)...and this gave me a 1.75 60'. This is on a MW3500 2.0 converter, full weight, headers, TR224...


What are you 60's and what psi do you run?

Between 19-21 PSI always worked well for me. I noticed they didn't like to go to low.

Ditto what he said...I've always run mine 20-22 psi. Lower does'nt seem to work with Nittos. Also make sure you do long burnouts to get'em hot!! They also seem to hook very well after you have just come off the highway on to the track with no waiting in the staging lanes...Randy

20-22 psi HOT seems to work best. This is usually about 16-20 cold (largely depending on the weather.)

Yup, that too! After hot lapping a few times they really start to hook!

i always went 18 piping hot...get those things cooking good in a burnout, they need it

I have always went to 16 psi cold and have hooked as hard as I would want to on the stock rear, other wise I think it would go :bomb: . But of course I am a 6spd.

I am the ONLY who likes this but, I run between 11-12 hot on my 17" Nittos. Easy 1.6's on poorly prepped tracks (Commerce). I'm sure a good track and prep could put me in the 1.5's for sure.
