This has been popping up again lately. I know i have posted this before but here it is again for people just trying the Q3 on the track. The info is straight from dunlop sent to me in an email. i just copied it and posted it in here.

AGAIN THIS IS TRACK PRESSURE NOT STREET you will eat up the tires if you do this on the street. Also this is Q3 ONLY no idea about the other brands.

Hi Mark,

Below info is from our test rider .........

The best and easiest way to set your tire pressure is to start at 33psi cold front and 31psi rear, do a track session, then as soon as you come off the track, check your pressures and adjust them to 35 front and 34 rear for the Q3s. Don't be worried to try +-2psi depending on how polished or corse the track surface is. Lower psi for more polished tracks and higher psi for more course tracks.

One of the main reasons the Q3 is so outstanding in the wet is because they heat up so quickly, there is zero benefit to using tire warmers, your out lap should always be a sighting lap anyway! The only time I would ever waste the extra time and effort with warmers would be on the first morning session if it was very very cold out ((40f), but in that case the entire session would be a sighting session and not much fun!

I printed out these directions from your previous post (thanks) and tried them a couple of weeks ago at the track. The pressures provided by Dunlop are much higher than I would have thought; but I gave them a go anyway.
I think what is important is the caveat about adjusting the pressures based on the track surface. My local track is very smooth, with a fine grain and some polished sections. Anyway, I dropped the pressure a couple of pounds to adjust for the smooth surface and was very happy with the results. Still, I was running several pounds more pressure than all of the other people using Q3s. (A favourite at our track.)
Many were surprised when I showed them the email from Dunlop, and a few were converted to the higher pressure (warm pressures less two pounds).
Another thing I noticed is that my front tire was much cooler than my rear, and so I ended up dropping another pound out of the front tire. If you can borrow an infrared temp gauge while you are at the track, play with your pressures and measure the relative temps.

yea i feel you man. coaches at my track were saying much lower as well. i was surprised with the email but i did what it said had a great day

Just curious; did you check your cold pressures later, after you'd adjusted hot pressure to Dunlop's spec? If they're saying the tires work best at 35/34 PSI hot +/- 2, typically you'd expect to see 5-6 less cold.

thats a great point. no i did not check them. didnt even think to do it. i will be at the track in 2 weeks so i will do it and report back.

Yes; I did. I think they were 30 and 28. But it is best to set up the tires cold as indicated and adjust when warm as indicated. The pressures between cold and hot can very dramatically depending on how much moisture is in the air inside the tire.

It is best to use a hand pump; but if you are using a compressor, make sure that the air tank has been bled recently. Condensation in compressed air can cause significant pressure spikes as the tires heat up.
