Tyre Pressure

Hi Guys,

What would be the best tyre pressure for a R33 GTST Series 2 with stock tyres n rims???

cheers

High! Try about 38-42 warm you will notice much better handling than at low pressures

I use 32psi all round, and it feels tight, but not with too much road noise. I guess you should check what is written on your tyre?

I'm not sure about the 40psi mark... sounds like over-inflating when you're talking about stock tyre dimensions?

[Thunder35]

Thanks guys!! I looked on the door panel and saw it said tyre pressure should be 32psi all round!

Car manufacturers give recommended tyre pressures that are best for the smoothest ride, not the best handling.

If you like a nice smooth ride, put them to 32psi.

If you want the best handling put it up high like Duncan said around 38-42psi. I always have my tyres at about 38psi.

Hmm.. interesting.. I tend to put mine on 32psi..

Having them high 40+psi does this push the inner tube out a bit and change the shape much..

might have to try it..

cheers

There are 2 main things that happens with higher tyre pressures:

1/ Much firmer tyres, basically the same as fitting firmer shocks.

2/ Less tyre wall flex which is more important on high sidewalls like stock ones. Less difference with big rims/low profile tyres.

I took my old gtst (king springs, 10psi boost, otherwise stock, and with a passenger) around Eastern Creek in 1.57 on road tyres (Falken fk451) at 42psi

Of course it is all totally different with race or r tyres, they have very strong sidewalls and tend to be designed for 30-35 psi hot.

Like shyster said, manufacturers want comfort, not performance

i got brand new tyres at TYREPOWER on my stock rimmed r33 S1 and they said to use 36psi

but i alot heard that use lower psi for comfort and higher for performance or something like that....not too sure

hmmm.. i'll try it this week when I get a chance.. don't like over inflating.. but i'll see how it goes..

Im asking here because I didnt want to start a new thread. and yes I have searched.

I have a 4 door GTS25 R32 with 17 inch rims. What would be the best tyre pressure?

Thanks

I would also like to know the best pressure for 17's (255/235). They don't have it written on the tyre as they're japanese (Potenza's)

Yeah, I've noticed the same thing. I usually run about 33-34psi in mine (stocko rims/tyres) and I've found that the ride's really good, but the handling sucks; it rolls on the rims. But at higher pressure the corners aren't so hairy, so yeah I'd be going up around 38psi for handling... but for everyday use, the 32psi would do you just fine.

whats the best tyre pressure for stock 16" 205's at the drags?

when's the best time to check the tyre pressure btw.. do you do it when it's coldish? or after you've warmed them up..
