First track day on my new 1125R. Just had a set of Michelin Power Pure's installed. Michelin does not provide any pressure recommendations. What pressure is recommended for track day usage? I assume the OEM pressure recommendation should be used for normal street usage? | ||

If there is a tire dealer at the track, ask him. Even if you didn't buy your tires from him. I've never met a track tire dealer that wasn't a good source of information. | ||

28 psi or there abouts is a good start, check them after your first session and go from there, there has to be someone there to advise you videos too  maybe we need a track vid thread | ||

I have power pures as well. They recommend 42 psi on the side of the tire  That's ridiculous. I run 36.5 on the street and am considering going softer. (Message edited by clutchreaper on May 27, 2012) | ||

i just finished 2 days on the track with my xb12 since the 1125 is down atm, but i set them cold at 32 front and 34 rear..did a session and they went to 34 front and roughly 36 rear..i run the 34 / 36 on the street btw.. But what Duggram said is the best bet! (Message edited by frinzo on May 27, 2012) | ||

i have two track days on mu Pures - 30 front 28 rear. Someone here said the Pure are sensitive to pressure changes in that the handling will vary with a couple of pounds difference. I'm not a good enough rider to notice the change I guess. I give you this so you might have a considered starting point. Enjoy your day! xo | ||

> They recommend 42 psi on the side of the tire Run from whoever told you this. They are an idiot, and all of their advice on any subject is now suspect. | ||

Thanks for the help. My instructor at the track recommended 30 psi front and rear. He said that it was a good starting point for my riding level. | ||
| Jdugger |
Your instructor offered reasonable and decent advice. It might not be perfect for those tires -- Michelin tires usually like a little more air in them for the front -- but it's reasonable and decent advice. | ||

28-30 is very low. I run mine at 36-38 cold. it handles so much better at this pressure, and your front tire will wear drastically better. if you don't believe me, try it for yourself. | ||

The pressure on the sidewall of the tire is the MAX pressure to get the load range for the tires, that is only if you are carrying the max load on the bike (passenger+gear, etc..) it is not the recommended pressure for riding or track days. | ||

Torquehd - on the track, or on the street? Those look like perfectly good street pressures, not trackday pressures. And ++ to "The sidewall pressure is NOT the recommended pressure." It's the highest you should go on it, cold. The trackday tire dealers are great, though. | ||

Tire pressure is directly related to tire temperature. If the track and ambient conditions are cool you need less pressure which allows the tires to deform more and thus heat up quickly. And even if the ambient conditions and track are hot, your tires won't get hot until you have run some laps. As your run time progresses, you should periodically check your pressure and adjust as necessary. My rule of thumb is to run at 28 PSI front and rear for my first session. As soon as that session is over I check tire temperature of both tires. They should be hot to the touch. If not, I drop the "not so hot tire" another psi. If they start to get so hot that they "blue", which is the oil separating from the tire compound, they are too hot and you need to add pressure. As the air in the tires heats up, it expands and increases the tire pressure which helps to counterbalance the increase in tire temperature. The bottom line is that you want them to be as hot as possible without blueing, since a hot tire is a sticky tire! | ||

I run at 32 psi. But run one session at lets say 32. Then go lower then go higher and see which gives you your best time. What works for me may not work for others on the track | ||

I run power pures and they love 34psi |
