I'm about to run these tyres for the first time and was wondering if someone could give me some help with COLD tyre pressures. And what is the optimum HOT pressure i should be aiming for.

I'm running these on my Toyota Supra, i'm asking you guys because the GTR and Supra are around the same weight and would like to save some time chasing the optimum pressure for these tyres.

Thanx :rant:

We use these on a GTS-t and maintain 30-32 PSI hot. Start at around 24-25 PSI Cold and adjust from there.

Which track and how many laps?

Ian do you start with same pressures front and rear left and right? generally you will get 2-3psi extra heat in front v rear and 2-3psi inside v outside tyres. So for example Oran Park if you are aiming for 32 all round maybe start with

RF 25

RR 27

LF 27

LR 29

Duncan, yes I start with around 25 psi all round and adjust at the finish of 1st Superprint 3 flat out laps. At EC RF and RR are always higher after running than LF and LR and I adjust all to 31 PSI.

Dont be worried to much about COLD pressures as long as they are ball park it will be fine . The key is to get to your designated hot pressures asap . Say 38psi is your target ( thats mine for toyo888's) ill start cold at 35psi do my sprint ( 4 laps) and when car returns to pits quickly reset pressures to my target of 38 psi as they have usually gone over this . Ill do this for the next seesion and then find that they are all at my optimal pressure by the third sprint and no need to reset.

32 psi Hot sounds a little low but hey all tyres are different that's why i am asking.

What i'll do then is start at 28 psi cold and work down until i reach about 32psi HOT.

I'm doing a track day at Eastern Creek, 20 min session, 5+ hot laps taking into account warm up and cool down laps, good point about the pressures front to rear and side to side, i'll monitor it and let you guys know.

Thanx again

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
