Smile Tire psi question

My truck in sig. Im gonna try out the new converter Saturday. Got some 28x10.5x15 ET Drag slicks. Where should I start on psi? I used to run 10 psi on my last mustang but it was a totally different set up. Thanks in advance.Btw, any ideas on what I may gain with converter/stickys?

I would start around 18-20. I forget exactly what I run my 28x11.5-16 at but I think it was 18. I had plenty of traction so I was planning to up the pressure and haven't been back.

I normally start around 11-12 cold... after the burnout, you'll be about 14-15.

If your talking Slicks, the pressure is typically run 2-6 psi less than Drag radials. I run my ET Streets at 18, my GY SS at 19...both hot for 1.5 sixty's.

I usually start out at 20psi, then work my way down 2psi each run until it sticks. Personally i dont like running low psi because it seems to wobble on the top end which is kinda scary.

With slicks and street tires it tends to do that. After I put my skinnies on up front it helped with this alot.
