track day tyre pressures


Recommended Posts

hey guys, im going on another track day in a couple of weeks and im wanting your opinion on what tyre pressures to run, i know there are lots of variables that i need to consider on the day but just a rough figure would be a good start.

the car is a zre and the suspension is stock except for a rear swaybar and a front strut brace. last time i was on the factory tyres (which are crap imo) and ran i think 42 psi front and 40 psi rear.

im now running some good falken tyres and added camber bolts. what would you recommend trying this time? was i close with the pressures i ran last time or way off?

any help will be greatly apprciated

cheers

cool good starting point. should i run the same front and back? also is it best to up the pressure when they tyre is at operating temperature or cold?

cheers for helping.

erm, im not that great with these set ups as im a newb as well,

when i went track, i kept it at 35 warm, and when it becomes cold it drops down to 32, all around

a friend told me that tyre pressures dont play a huge difference when it comes to street tyres.

ok thanks mate, appreciate the help. ill give that a go for my next track day. i had a feeling the pressures last time may have been a little high.

only thing i was thinking even though they are street tyres higher pressure would make the side wall stiffer to prevent tyre flex?

You really need to experiment with your car, tyres and the track you are on. 40+ is to high for street tyres, you will end up with less surface area on the track. As a general rule I'd go with 38 +1/-2...

cheers guys. i think ill try about 38 psi next time and see how that goes. i realise i need to see what works for me on the day and the track im at as i stated above i just wanted to see if the pressures i ran last time were close too what i should run, turns out they were a bit high.

is 32 psi good for street driving?
