youve just made me think, when you came round thats one thing i noticed on you car is that the tyres looked a little low on pressure:scratch: noticed it more on the fronts.

It really deepens on style of diving and tyre design. I found that "V" tyres work great around 17.7 bars while asymmetrical are better around 2.0 bars. Tyres were 195/45/15.

In you case I would try with 1.8 since 16" have stronger side walls than 15"...

'kin'el jure! 17.7 bar!! nearly 250psi, im guessing either thats a typo or you've been riding around in a great red shark in true Hunter S Thompson style! :laugh:

Raj, it depends on temp, loading, driving style, etc. I had a dodge charger in Florida last month and it got a flat, when i looked at the handbook for the correct tyre (sorry tire) pressures there was a 13page section just on pressures, fecking yanks gotta make everything complicated

.................but yeah 32/30 is about right :D

Yep, my typing mistake. Tire not tyre should be at 1.7 bars not 17.7 bars. Still if somebody wants to try how five is rolling on 17.7 I0m praying for him :sos:

Most alloys i build up i put around 31psi in. On my own tyres i just keep an eye on the wear of them. If its wearing in the centre of the tyres more than the outside then the tyres had to much pressure in it. If the shoulders are wearing more than the middle then it has to little pressure in it (or youv been driving like a c~~t). Even tyre wear = spot on pressure

LOL probably because i havent checked them in a while as they dont seem to loose that much pressure.

As a rule and if i dont know the car they get 2bar. I run 2.2 front and back, the front tyres wear even and i my n/s/r tyre wore quite bad on the outter edge

I have always used a little less pressure in the rears than most but I only do it because I have always found the rear of the car to be unstable under heavy braking, probabley some thing to do with 5s and the same with the clios having very little rear end grip.

Only thing I will say is use a decent gauge to measure tyre pressure, relying on that pony gauge on the foot pump wont get you anywhere:)

lol, i did using the footpump as i wanted a quick ex errr:scared:size :D
i could have taken the wheels down to the local garage to pump up..which i'll be doing tomorrow to check the pressure:D
