Running diablo strada's in 50-60 degree weather on my xb12r. I think I was setting it at F36/R38 in 80-90 degree weather. What would the appropriate tire pressure be for this drop in temp. |

Isn't it supposed to be 34/36 ALL the time? I've never seen any thing anywhere (for any tire or for any bike) that recommends different air pressures for different ambient temperatures. Load, yes... temperature? No. This isn't motor oil we're talking about... |

you do not need a seprate cold weather tire preassue. BUT You do need to check your tires durring cold weather riding. Remember cold weather makes the air in your tires "shrink" causing a loss in air pressure. |

The tire pressure drop is approximately 1psi for every 10 degrees of change. colder lower hotter higher The things you learn at work. Thank you Ford and Firestone. |

Teeps, What do ya mean by: colder lower hotter higher Are you saying in colder weather one should lower the pressure ?? If so I don`t think I wd. agree with that as well as adding pressure for hotter temps.??? I must be reading this wrong from ya? |

The owners manual (for XB12's) says 36/38. It doesn't say anything about changing pressures in the winter. I too would recommend more attention for your tires in cold weather. It also takes longer for them to heat up too, so be careful when you first get on the road. What about on the track? What kind of pressures are you guys running? |

Hogs... I thinks what teeps was saying is that the tire pressure automatically changes as temperature changes because air expands as it gets hotter. So when the temperature outside dropps ten degrees you will have approximatly 1 psi less air pressure in your tire. But you should try to keep that pressure the same so when it gets cold out you will probably have to add some air to get back up to the reccomended tire pressures. Hope that made sense. |

Aj06bolt12r, Exactly right. |

When it's cold outside, I run a lower air pressure in the tires because it gives a bigger contact patch since the tires don't get to the same sticky heated temp. Everyone might not agree, but it has worked well for me on the track on cold days. The last track day, the temperature didn't get above 50, and I ran about 28 psi, and I didn't slide a tire all day. |
