Tire pressures on the track???

I've got the BT016's and run 36psi on the street. What is a good pressure to run on the track? Last time they felt stiff so I let some air out without a gauge to see how much, just let a bit out.

ya best to ask John or Brandon. With street tires i really wouldn't know what to set them at b/c they just get hot and slippery not sticky like good track tires. if your under 2 mins i would invest in track tires just for confidence in them aswell.

Probably somewhere around 30-26.

36 will put you on your head once they warm up.

John will put you straight....

I let some out after the 2nd session last time then let some more out after the 3rd and they felt really good. I just didnt have a gauge to see how much and was wondering what a good start point is. 26-30 sounds good. I'll prob start the day around 30 and go from there by feel. Thanks guys.

Cold 28 to 30 psi front and rear. Those seemed to be the ideal pressures for all hyper street sport tires I've run on the track. Including the 016's.

So I talked to John directly, very nice and helpful guy. His recommendations, if anyone else needs them also, are 28psi front 27psi rear cold. Hot off the track 32 front 31 rear. Thanks everyone..

Watch for the tire bluing on the rear. You'll know if they're to low, the bike will squirm on ya in the corners. Good luck and have fun.

The blueing you see is nothing to worry about. It's just the oils in the rubber coming out from temperature swings. As soon as the tires heat up, the blue goes away (b/c the oils go back in to the rubber). If you're not using warmers, just go out 50% on first lap, and slowly increase to your intended riding levels. Basically, depending on length of track, two laps should be good to go.

I always run 3-4 PSI lower in the rear than the front. Keeps the bike from highsiding I think, but maybe causes the front to wash out quicker.

Ask John or Brandon. "Stiffness" or lack therefore isn't what you're going for, its proper operating temperature.

I spoke with John last week. Tires felt good all day at the pressures he suggested.
