I was curious about tire pressure on pilot powers for a track day versus that for normal riding. What would you run for aggresive riding on the track. On the street I run 35 psi in both.

Pilot Powers I was told 32 PSI front and rear hot off the track.

Do you mean 32 psi after a few laps? Or 32 psi cold before they run.

I typically start with 30/30 cold for Pilot Powers.

He meant 32 after a few laps. Check your pressures as soon as you get back to the pits...they can cool off pretty quickly.

Exactly. Go out for a full session and when you come back in check your pressures right away.

Also, look into buying a decent gauge if you don't already have one. If the gauge has been dropped or been lying around in your glove box for a while get a new one since the old one is out of calibration.

I typically ran 30F/28R cold pressures. Checking them when getting back into the pits the temps would be up to around 32~33F and 30~32R, depending on track temps and how hard I was pushing it.

I always checked the wear pattern of the tire after each session to check for cold tearing or weird wear.

Thank you that is exactly what I needed to know. I think I will start 32 front and rear cold and see where im at hot. I weigh a little bit 245 suited up And go from there. I was just a little afraid to run that low of pressure on a non race tire. Also would you change much pressure wise for the street? Im not talking slab or anything just mountains twistie stuff .

I run 28 front 23 rear. I get cold tear if I run them with anything higher than 23 rear.

These are cold pressures.

^^I run close to this.
28 Front and 24-28rear on the street(more like canyons). I like how the tires feel at the lower pressure, when its over 30 in the rear the tire feels less glued to the road. The front feels OK at 30-32 but it would frequently lock up on initial bite when pulling stoppies.

oh yeah.. i only weigh 160.

No stoppies for this kid

I don't ride my SV's on the street. Instead it is a GSX-R 1K. Typical pressure is 36/36. No issues with grip on the roads. Unfortunately, no canyon carving here but we do have some nice country roads. Just got to watch out for tractors!

30 front, 28 rear is a good starting point. The outside temp has a lot to do with it. On cool days, lower pressure is the ticket as for lower pressure will cause the tire to heat up more thus providing better grip. Running a high tire pressure will not allow the tire to heat up as fast and or get up to full temp. I typically run my power race tires at 30 front / 22 rear on day 80 and below. 80+ I run them at 31 front / 26 rear.
