blue03636 Posted September 24, 2011 Report Share Posted September 24, 2011 This will all depend on what tires and what they are used for. Quote Link to comment Share on other sites More sharing options...
ohdaho Posted September 28, 2011 Report Share Posted September 28, 2011 (edited) I would run what the manufacturer suggest. They'll give you numbers for track vs street.The engineer in me, says the rear heats up faster/hotter than the front esp on the track, hot air expands to a greater volume hence the need for lower rear tire pressure.

Tpoppa Posted September 28, 2011 Report Share Posted September 28, 2011 One of the fastest street riders I've ever seen ran 42R 38F. Tried it, didn't work for me.I run 36R 34R or 35R 33F depending on temps.Lots of people like to be around 30/30.Lots of different preferences on this.

APCh8r Posted September 28, 2011 Report Share Posted September 28, 2011 You usually run less in the rear compared to the front, as it will allow the rear to flex under load. As others have said you need to go with the pressure recommend from your track side tire supplier. Quote Link to comment Share on other sites More sharing options...

MidgetTodd Posted September 28, 2011 Report Share Posted September 28, 2011 Need to be checking pressure as you come off the track and adjust. All pressures trackside gives you will be hot pressure and it will differ depending on track surface, riding style, weight ect. You and I hop on the track with the same bike and run 10 laps the hot pressure will be different for both of us when done Quote Link to comment Share on other sites More sharing options...

MidgetTodd Posted September 28, 2011 Report Share Posted September 28, 2011 They give you hot as well not just cold Quote Link to comment Share on other sites More sharing options...
blue03636 Posted September 28, 2011 Report Share Posted September 28, 2011 Michelin has never given out hot temps, they set them cold and forget it. If someone is giving you hot temp for a michelin then they are just setting them cold and running them to check the hot pressure. Every time I have talked to someone there they will just give you a cold pressure. Quote Link to comment Share on other sites More sharing options...

Every time I have talked to someone there they will just give you a cold pressure.Yes Michelin's are the only one that does cold pressures. This was the main way for Power Races, however I have talked to David Grey from Sportbike Tire Service and they have been doing hot pressures(warmers - not off track pressure) for the Power One sets some.

blue03636 Posted September 28, 2011 Report Share Posted September 28, 2011 Last I talked to him about it (end of last year) he still just gave me cold pressures. I have never set the power ones to a hot pressure. Quote Link to comment Share on other sites More sharing options...
madcat6183 Posted September 28, 2011 Report Share Posted September 28, 2011 And if you are running Power Pure's there is no temps. Just guess and check but nothing out last time I talked to anyone.I set mine cold at 28f/26r, then I reset them to the same after 2 sessions and warming up. Then I forget about them unless it gets real hot.Keith Stone, I love you! Quote Link to comment Share on other sites More sharing options...
