Radial slick pressure

Having run radial slicks of various sizes for 20 years, over 5000 passes, on two different doors varying greatly in weight and power, one that has 60 footed a best of 1.28 and the other 1.17, both launched off the footbrake, I can tell you that 18-22psi is the sweet spot regardless of power, weight and tire size. Some run as much as 24 psi, but they are typically lowered powered cars and the result is they are also not using the entire thread face.

That said, the extension and rebound of your rear shocks will need to be optimized for the radial tire.
