Et Front and Et street tyre pressures ?

[mex351]

So I got some Et Street's cheap and some Et Front runners to match...just wondering what size and tyre pressures you are using in your car.

I have a xf ute with a NAT ASP 250 running 12.2 @ 112mph so far but have been having trouble putting any RPM on the convertor to launch the car on MT radials,hence the swap to the ET Street's.I have some 24x4.5"x15 fronts and 26x10.5x15's rears with tubes on a 15x10 rim to help stiffen the sidewall a tad. Havn't driven on slicks (yes I know the Et's are a treaded slick) in a long time and it's a different car aswell so any help with car set up would be appreciated.
