First day on the track Monday. I Think I covered all the bases. Just was looking for what tire pressure you experienced guys are using on the track. Not sure f this has been covered. I cant seem to find it. Thanks in advance! |

Type of tire will make a difference in recommended pressures. You're going to have FUN - but you WILL be running lower pressures than "recommended" by the manufacturer. What tires are you running? (Message edited by slaughter on August 10, 2008) |

I ran 30 30 during my track day. It seemed to work ok. But I am a newbie. |

30/30 is a good general recommendation for Dunlop and Pirelli DOT's. IF you have a manufacturer's rep selling tires there trackside, be sure to ask them. They'll know better given the local track conditions - temperatures and whether the track is likely to be wet. Michelin has some really DIFFERENT pressure recommendations on a couple of their DOT performance tires - I can't make recommendations there. |

I like it a little higher, 32/33 on my OEM Pirellis. 30 gives me too much movement until they are really warmed up, I have seen no downside to 32/33. |

I'm curious as to why you run the tires at lower pressures on the track. Won't that cause the tires to overheat?? |

They will heat cycle - get hot on track, cool down between sessions, get hot again on track. You need/want the tires "hot" for the most grip you can get. |

I'm very impressed with the OEM Pirellis. At Road America, I forgot to drop pressure. Rode with the 42 I run on the highway. Still got half-way into the pitchforks on the left side, points on the right, no slip. This bike leans at ridiculous angles. Z |

Please note this is a personal as suspension settings. Also, check throughout the day, you can easily loose pressure during a full track day. Someone (Henrik?) once posted a formula for the % you want your tire pressure to increase from cold to hot and the trick was to start low enough that you'd hit the "hot" pressure you wanted to run at. I just set it 32f/33r and check after lunch. |

Thanks everyone! I can't sleep! can't freaking wait. But I'm off to sleep. Thanks for the input. I'll let you know how it goes and what I ended up with pressure wise! |

I've always felt a tire can get "too hot" and if the rubber gets soft enough, you lose traction just as if the tire isn't hot enough. That's when it starts feeling "greasy." I dunno, since I'll NEVER be remotely near the guys like Spies, Mladin, Rossi or Hayden I'll just continue running the same pressures I run on the street. Haven't had any problems yet. Thanks, Everyone! |

I ran 34 in the front and 32 in the rear and I was fine. I'm new and not going as fast as some but worked out well for me. Thanks again guys!! |

The usual practice is more pressure in the rear than in the front... |

I asked "the experts" at California Superbike School this question. Here is their response: No I would not run lower pressures for track. Sometimes riders choose a higher than normal pressure for highway to conserve wear, but not lower than recommended for track riding. On the other hand, tire tech is starting to change rapidly so personally I would ask a tire rep these questions when at a trackday or race. They will give the most current and reliable data that would vary from tire to tire and brand to brand. Cheers! |

I ran 28/29 on mine. They stuck great, one warm up lap and they just gripped. Used the entirety of the rear tire by the end of the first session, and well into the arrows on the front. |
