Stock Wheels deflate?

[pushead]

Not sure why, I pumped my tyres last week on my good old stockies at 35 on all 4 wheels, after 1 week all the wheels deflat pretty dramatically, lost 6 psi on each wheel and the rear left even more 20!!! I do normal road driving but do infact turn corners quite hard and fast.. does this effect it? if so does it effect it that much that it looses 6 psi in 1 week?? thanks all..

6psi in 1 week the answer is no! maybe you are leaking in a major way??

6psi - look for a leak in the valve

20psi - look for a nail through the tread.

i think that u know that u got bad damage on ur tyres if u see a ring that follows your tyres ... hard to explain ... cause i had a leak in one of my tyres and it developed this very noticeable mark which followed the outer edges of the tyre ... but i'd get it looked at ... also u might wanna run ur tyres harder... as it improves tyre wear and ride comfort ... but might give a bit less traction ... someone correct me if im' wrong...

This happened to me once years ago....never found a puncture, but finally replaced the valve stems (use the metal ones not rubber, they look better) and valves...that seemed to work.

The consistant loss across all three tyres is odd. Did you use a service station gauge when you inflated them to 35 the first time? They are notorously inaccurate and unreliable, I have a little $20 tyre gauge that I leave in the glovebox for checking pressure (in fact, only use it - dont even bother with the servo gauge most of the time).

BTW the new 'digital' gauges at some servos appear to be crap most of the time too...

I have been told that you should never check you tyres once you have driven your car, only when they are cold. The resaon being that the further you drive and the hotter the day the more pressure you will have in your tyres.ie hot air expanding.

1 check all pressures when cold with $20 gauge from kmart and remember how much each are down.

2 Drive to petrol station if you dont have a compressor at home, add the correct amounts to each tyre and check with your own tyre gauge.

This way you will know for sure, how much of a leak you, if any!!

ps down 20psi i think you have a nail

Good luck

I checked my tyres (Falken ZE-502 - 225's) on the weekend and they dropped about 4 PSI in about 6 weeks.

My mum got her tyres pumped up with urmmm whats it called nitrogen or something (wild guess i have no idea what its called). Cost her like $60 to have it done and mannn their is a difference. Tyres are never REALLY hot, never changed PSI and drives more smoothly.

It's good thing to check stock tires time to time!
