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..

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...

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.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
