Tyre pressures

[Col]

This topic generates plenty of interest, and opinions can differ significantly.
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.

[kitkat]

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...

[Red Baron]

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'

[red63sprint]

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
