tyre pressure

[hippy]

my front tyres are different from the one on the back ... i mean they are pretty much a totally different tyre, same size though ... i was wondering what tyre pressure i should have them on... they are 16"

thanks

[skyline33]

the recommended pressure by all tyre shops is 32

the recommended pressure by all tyre shops is 32

I disagree mate sorry! AAMI and myself recommend 36psi... i use 36psi and AAMI (when i went on an advanced driving course(3 days ago) recomedned 36psi for my car) the only skyline there on the day...It was awesome

32 is what I drop it to on track days.

36 sounds right.

Different tyres, different requirements, but most are 36-45 for performance (suck for comfort though)

[skypilot]

i have 36.. it works very well

[blind_elk]

36 sounds a bit much, but it depends on the tyre.

I was taught to run 2psi higher in the front. It holds the tyre firmer, and reduces understeer.

Silver-Arrowz, you really should be RAISING the tyre pressure for the track, but check the pressures HOT. Anything up to around 45psi. Just depends on how the car feels, and what tyres are fitted.

[Duncan]

Good point, 36-45 is HOT pressure, not cold. Depending on the track you may need to adjust individual sides or front/rear as well to keep it balanced. Usually just same all round on the road.

I've run around eastern creek with 40 psi and the tyres go off bad. Get about 2 or 3 laps only. I've been told by others to drop pressure, and I've managed to stay out there a lot longer.

It's not a simple case of raising or lowering the pressures for the track. You have to find a happy medium which will allow the tyres to bleed off excess temperature. Either too high or too low pressure will cause them to overheat. Usually low to mid 30's for pressure is good but you really have to experiment.

I run mine on about 36 for the street, used to run up to 40 on my previous car but found the sidewalls got slightly distended after awhile. I haven't taken the car to the track yet so I don't know which way to move it from here, I'll have to experiment myself.

so thats 36psi cold ? for the stock tyres/rims ?

[Jay95R33]

I'm running 38psi all round with mine. Wear is dead even, and it seems to have sharper turn-in.

But this is just for street on 225/50/16's.

ok i got yokohamas put on the car ... standard size ... 16"s the guy said to put it on 40 psi !! .. so thats what i'm leaving it on .. what do u guys think?

[whatsisname]

I use to run 38psi in my Falkens. I've since had a set of RE540's fitted & was recommended to run ~30-32psi (cold) for the road. These tyres have VERY stiff sidewalls.

When it come to road use it really depends on what your driving style is?

Traffic light specialists would probably benefit from lower pressures (~28-30psi cold) as the extra sidewall flex "should" help with grip. Plus the ride will be a tad more comfortable.

If you're more of a twisty road person then extra pressure "should" be better (36+psi cold).

I'm no expert on this stuff so I could be completely wrong!? And you'll end up with lots of - :burnout:

32 psi on mine cold

cheers

I found 37psi (cold) was good but I have run 45 psi (cold) and found it a bit to harsh, my tyres are stamped 55 psi max.

What I have noticed is the firmer the suspension the more the sidewall flex becomes an issue.

If you are worried about the presure getting to hight when the tyres are warm then fill them with nitrogen, only problem I have is to top them up I need to go to the tyre shop.
