I run 25psi in the front and 50 in the back.........maybe 40 in the wet but usually stick at the same pressure!

I ran 25 psi front and 30 psi rear at Nutts yesterday. Poor tyres didn't help but it seemed to be a good combo

Yup..........alot harder to loose traction in the Chaser than it looks!! Its suspension set up is set up for serious traction!! Bon used run 70psi in the back

70? do the tires not absolutely shred themselves with the heat straight away?

What pressure are they when they're hot Chuck? What tyres you running actually? And they're 265s aren't they?

Jebus!

A lot of it depends on tyre width, power of the car and type of tyre.

i had 40 psi in my road wheels last time i was in nutts and they delaminated after 1 lap....ONE FECKIN LAP due to the heat! so i ran after, although my old tires that were sitting out in the garden months lasted ages with 30 in them.

i ran near 50psi on my 225 federals in mondello,i was afraid to see what pressure was in them when hot

anyone ever used tyre deflators?

Nope...................take a while!

@ Darragh...............i run federal 595 RS's

I found my car goes better with lower pressure, 22 - 25 in front, 25 - 30 in the back. Then again this depends on conditions and power etc..

I'd say a bit lower might have helped you out a little up there Ste

Sounds about right to me

does the higher pressure really make that much difference ye????

well the lower the pressure the more grip on the ground, the higher the pressure the easyer it is to spin the wheels...

less pressure + hot surface = hard to spin wheels & drift

ah maybe thats why my wheels wont spin up in 2nd in dry well that and the MASSIVE TURBO LAG

You using RSR's chuck?? they mightnt delaminate so quick as there're designed for track use, and getting hot..

I run 30/32 in the front and sometimes 25 in the back to stop them delaminating..

If tires start delaminating let the pressure drop, its amazing how much the psi rises
as soon as ya do a few laps in a driftcar!
