A popular pressure for street use [including some spirited driving] is 32psi cold, for both front & rear. This is a good starting point and allows you to experiment by altering pressures +/- depending on handling characteristics.

33 front, 34 rear.

40psi cold on the road will shake the s**t out of your car.
We don’t go that high for track days. Anything over 41 - 42 hot, the performance of the tyre drops considerably.
Most will use 30 - 32 for spirited street driving, especially not having smooth black tops in Sydney. For the track try 36 - 37 cold and monitor the pressure after each run so as not to exceed 40 – 41.
If you look on the sidewall of your tyres you will see a warning to the tyre fitters not to exceed 40psi when setting the bead. It’s put there for a reason.

The door says my stock 14's should be at 28 all round, but I find 32F/31R cold works great for my P6000's.

jonno.

i run my azenis RT615s at 28 allround..

same here...except mine are oly the RT215's

40psi front and rear with C-Drives 195/60 R14

i noticed anything under 35psi and grip levels go down, havent really experimented though.

I run 34 front and rear on OLD tyres.
But my tyres have no grip at any pressure - I keep the tyres pumped cause I dont have power steering...

Road tyres on the road, 34 front 32 rear.

Typr R, depends what you might be getting up to, but because you probably won't generate temps 30 all round.

indeed - the only variation to the above i use is 30psi cold in summer

I run 34psi with RT615 195/60/14 for the road, and found at the track to be 29 cold, which gives 36 hot.

Yeh, I got a coupla new shoes a while back an' the guy's at the tyre shop plonked 40pis into the thing an' the ride was so humpy I thought i was on the back of some fleabag camel cruizin the sahara. Dropped it down to around 32 an sweet sailing. No more frothy beer while drivin'

I know run 36psi F+R with RT615 195/60/14 (same tyres as Brad) for the road - and that on the new tyres is just about perfect!

UPDATE: At the Natmeet I had a chance to play with presures. For the track I found 32 hot to be the best. On the road I run 32 cold.

32-33psi all round cold on 205/45/16
