I reckon it's hocus pocus (that costs money). Regular air is mostly nitrogen anyway, doubt there'll be significant difference. http://www.aa.co.nz/motoring/tips/ask-jack...n-to-tyres.aspx http://aardvark.co.nz/daily/2008/0311.shtml |

Some light reading: http://z4.invisionfree.com/lexusaltezzaclu...?showtopic=1513 I'm sure there used to be many more posts to do with this but I can't seem to find them, it was a hot topic with many very heated discussions involved. Feel free to make up your own minds on the subject :-) |

Are we meant to fill our tyres with air when they are hot or cold? I did mine to 40PSI after a decent trip along the motorway at the dairy flat BP. Yesterday I took it up to the Mobil (cool digital air thingy) and they all came out at only 33PSI, this was cold, only about 1km driving at 50km/hr to get there. Needless to say I did them all to 38PSI cold just to be safe... but whats the Go? I'd almost be inclined to say do them Hot, because you'd be driving on Hot tyres once they get up to Temp |

Everything I've ever read says to fill your tyres cold. The variation you've noticed is probably more likely to different calibrations of the pumps at different petrol stations, remedy is to get a tyre gauge to carry in the car, that way you have a constant reference. |

The gauges at places like servos are very inaccurate, as suggested get one of those cheap little gauges to carry in the car to double check. |

btw i've heard its better to stick to the tyre pressues marked on the driver's side door. saves ruining the tyres (bumps in sidewalls etc). |

Just another way for the tyre companies to grab some of your hard earned cash! And also after read the link posted by JeremyFlower i see some people talk to much before posting. The reason Nitrogen is used in Aircraft tyres is that most of the wheel assemblies are made of magnesium or alloys with high magnesium content, which corrodes very easily. Nitrogen has a lower moisture content therfore less likley to corrode wheels. You'd be better off checking your tyre pressures more regularly, maybe with a calibarated gauge. Also are you going to go and pay $5 every time you need a couple of psi put into your tyres? |

The correct tyre pressure should not go beyond 3 degrees differance between checked when cold to hot. So if checked cold at 33psi and hot at 40psi that is 7 degrees differance so up the cold pressure say 3 psi then recheck hot to see if the differance is smaller. The reason for this is if the cold tyre is under inflated it works alot more creating more heat expanding the air giving the larger rise in the hot temp. |
