I'm now running 12x6 yoko 048 and can decide what to start at.

I was running 10s 032s and at 36psi front 34 psi rear filled with nitrogen and it was the best I could ever get out of 10s till the sidewall fell over every corner. And making them last 40min race,as if I ran 30-32 in them I got tyre bounce on hard braking and shredding tyres in 15mins
And at 40 it was it slide and tyres go off too fast too

The 12s got nitrogen in and a lot less side wall defection but do I run the same pressures or drop them a little as there med compound and lower profile.

Try out a few laps at different pressures? Sorry I have not ran any- but it's got to be the best way so you are happy with it yourself instead of trusting other peoples advice that may not work on your car!

That's what I done Saturday at llandow,tried all pressures up and down and found a good base. Then messing with the shocks and rear ARB,went tho a set of new tyres tho and 80 litres of fuel.but getting quicker so it all good..

80 litres!!! What pressures did you find best? As you say when you have an ARB and adjustable shocks it makes it hard to know what to tweek without spending loads of time testing- say using about 80l... lol
