| 1196421 | 2011-04-23 11:00:00 | I came across one of those new electronic pumps, very nifty in the way it completely deflated by bike tire as it tried to get a reading so it could pump it up to the designated pressure.:groan: When it was finished I got to push my bike to the BP down the road so I could inflate it.:horrified Almost as bad as the Mobile I visited, That one wouldn't stop pumping air in, and in my haste to get her off the valve was torn right out of the tyre and I got to push the bike all the way home.:illogical :D pwn |

| 1196422 | 2011-04-23 12:34:00 | Hey, regarding tyres pressures, average tyre pressure for any standard car is 30-32 PSI, a mid size car, anything between 34-38, anything with Low profile tyres you generally want 38-42 PSI (average 40 PSI). A van anywhere between 36-40, depending on what tyres it has, and weight etc. P.S. I am Manager of a tyre shop in Te Rapa Hamilton, if anyone ahs any questions about tyres and pressures, go to a tyre shop, most of them are all happy to check pressures, and they have proper equipment. And it should be free to check your pressures. |

I know road cars don't have their tyres heat up anywhere near as much as much as race cars (hence why that nitrogen gas some tyre shops advertise is virtually useless) but still always thought you were supposed to check when cold or fairly cold to get an accurate reading. |

The accuracy of the pressure reading depends only on the accuracy of the gauge, nothing to do with temperature unless the gauge itself is temperature sensitive. You are confusing accuracy of reading with variation of pressure with temperature, according to the ideal gas law PV/T=constant |
