What tyre pressure do you run at?

[GreyRex]

Hi everyone,

Can't really remember a thread about this and thought i'd see what people comments are on this topic. I've got 17's on my SRi Barina and run them at about 33/34psi. I went to a tyre place recently and he said to run them at 40... so now im confused. I know its more subjective than anything and depends on your car and driving style, but what do we all think? This guy said obviously they'll ride harder, but they'll last longer. Any comments welcome

40 all around for my 17's mate. Main reason is so that if i get a puncture i have a little more time to notice it before the tyre side wall is rooted, and that's what the bloke at TyrePower reccomended; where I got my wheels and tryes from. I always ran the 15's at 38 anyway, I never take any notice of the factory placard because they are always for best comfort.

I run mine at 36 all round, but maybe i'll put some more pressure into them now.

uhm..i have no idea what the conversion is..

i ran my cars at 2bar - 2.2bar. depending on where i was going, load, etc..

for the drags i dropped the front wheels to 1.7bar..

1 bar = 14.504psi at sea level

therefore,

40psi = 2.758 bar
38psi = 2.62 bar
36psi = 2.482 bar
33psi = 2.275 bar

1.7 bar = 24.656psi
2 bar = 29.008psi
2.2 bar = 31.908psi

[oneightoo]

bar is used mostly with weather readings. psi is mostly used for other pressure readings.. in australia that is..

i run at 38 psi front and 35 psi rear. tyres are 225/40/R18. a good compromise between comfort and handling imho.

Have an Astra SRI T - 17's with 40psi all round. Seem to wear very evenly. No problems. Have had 40 psi all the time. Owned the car since brand new for 3.5 years.

I'm running 38psi all round on my Vectra-B V6 hatch with factory alloys and 205/60/R15 Goodyear Eagle GAs. The ride's a bit harsh, but with -1 degree of camber (negative) it handles exactly the way I want it to at highway speeds.

i run 40 on the front and 38 at the rear. The tyres are 215/45/17
