Radial slick pressure

Myron Piatek · 09-19-2019, 12:04 PM

Rim width also has an in influence on pressure. The wider the rim, the more pressure you can run...which is better because it will extend the life of the sidewalls. I have the Hoosier lightweights on 10" rims at 21 lbs on my 3,540+ lb 360 Dart, footbraking and SS springs. Especially with new tire, you can usually see if the tire is making full contact all the way across.

But even if it hooks with more pressure, and theoretically goes a bit faster, you want to keep as much rubber contacting the ground as possible for a little extra "insurance" (consistency).

You should pick up a little ET and RT with radials over bias play.

You may need a touch more pressure once you get the car to leave harder (lower 60').

If I told you what I ran in mine at Indy this year, you wouldn't believe me.
