At this moment I'm running 40psi front and 38psi rear on 215/17/45 and surprisingly it feels better and had better fuel consumption. I guess the my manual's rating of 33psi front and 32psi rear is outdated.
Tire pressure, What u all put in?

QUOTE(zendengoh @ Feb 22 2008, 09:28 AM) dont u feel stiff?the road signal too clear and uncomfortable? I'm already on stiff suspension and the higher pressure makes the steering feel even better since my car no longer bouncing on the tyres anymore. I don't like driving on soft suspension.. feels like a boat and you lose all connections to the road.

QUOTE(alkt @ Feb 22 2008, 10:02 AM) walau eh! so high ar ur pressure...u sure ur tyres can take it? The max pressure rated for the Goodyear Eagle F1 that I'm using is 51psi. That's still a lot higher than the 40psi I'm using and even with the 10% increase after the tyre gets hot, I'm still safe.i'll try ur settings later but i'm on 225/45/17, pumped used the recommended pressure  That is nothing compared to my spare tyre. Recommended pressure is 60psi. Petronas pumps only go up to 58psi. I had to use Shell tyre pumps to fill it up to 60psi. This post has been edited by sleepwalker: Feb 22 2008, 10:28 AM |

QUOTE(GoldenHawk @ Feb 22 2008, 11:04 AM) I guess the wider tracks do compensate when filling up to 40psi. On a 15"-er, it'll start hinting a whee bit of grip loss, especially in the rain. The wider tracks would aquaplane easier in the rain but the wet weather properties in the F1 makes up for it. So far, nothing comes close to F1 when it comes to handling in the wet and I just love it when I leave my fellow friends in AD07 in a spray of water during rain.Had the same problem with my spare too  Using one from a Waja.At one instance, the entire tip/faucet popped off the tube while filling up!  Had to quietly stuff it back into the tube & leave Pity the next quy using it  |

QUOTE(xtracooljustin @ Feb 22 2008, 01:17 PM) dude u sure? i only running on 33psi for both my front (245/40/18) and rear (265/35/18). Can it really take 40psi?? Max pressured as marked on the sidewall is 51psi. Still a big margin to go... |

QUOTE(Esky @ Feb 22 2008, 01:52 PM) 40 psi is still within the limits of most tyres, but the more you pump, the closer it is to this limit, and therefore there's less safety margin to work with if the tyre hits a big hole or object on the road. just my 2 cents There's still plenty to go on my tyre. 51psi is max. I'd rather hit a big hole with a tyre full of pressure as the sidewall and rim will take less damage. Tyre will not blow out unless it was already damaged.Added on February 22, 2008, 2:41 pm QUOTE(gkl83 @ Feb 22 2008, 02:36 PM) i pump 32psi for all 4 tyres... car no bouncy/bumpy at all... Well.. my manual says pump to 60psi before use. On the sidewall fo the donut spare also says pump to 60psi before use.is it safe to pump 60psi on donut spare tyres? feel like will blow for a small tyre... last time i saw a bangladash labour pump a tire for his trolley, the inner tube blow...

QUOTE(Aeon_Clock @ Feb 22 2008, 07:19 PM) you mention cold pressure rite? But after driving a while the pressure becomes hot isn't it? Max pressure is max pressure, doesn't matter if it is hot or cold. Heat would increase the tyre temperature between 10-15 percent max as air does not expand too much.So what's the max pressure on hot condition? |
