dunlop q3 overheating?

I am running q3 on the zx10r and yesterday i pull out the bike out of the garage and saw my rear all blueish on the side, i had this only 1-2 time in the past with the zx6r but this time its a lot worse.

From what i read its after a big heat cycle and oil is coming at the surface,is the tire really overheated or its normal ?

Is it still ok for doing a trackday?

this was done on the street with 32 front 34 rear hot, about 300 miles of twisties and outside temp was about 75*

what do you think?

Your tires are fine and that bluing is more typical of a track tire after sitting from the heat cycles. It will wear off within a few miles and be right back to normal. From my experience though, if you let it sit for a few weeks and allow the bluing to settle then the tire will be very slick for a while before it returns to normal dependent on how much rubber you have left.

The tire has about 1500 miles on it, it has sit 4-5 days like this in the garage and i rode the same run yesterday and the tire was feeling normal and the blue was gone now.

Just curious on why you are running more pressure in the rear?

Your pressure's are to high especially in the rear. If you use tire warmer's at the track dunlop says 30f 28R hot off the warmers. If I don't use warmers at the track I run 30 front and rear and then check my pressures after the second session as the pressure rises. The dunlops are very pressure sensitive. I started spinning up my rear tire last track day in the third session and found that the rear pressure had risen to 34 I set it back to 30 and no more spinning up the tire on corner exit.

Tons of life left in that one for sure. And just to mirror what Techx said I start at 28f 27r cold on my GSXR 750 at the track and go from there. I dont use warmers either.

Maybe you guys can help clear something up here for me. As far as I know, I have always run more pressure in the rear per the manual and what many other people have said and done as I was learning to ride over the years but mostly per the manual. Are you guys running more pressure in the front than the rear?? Whats the different effect? I have never tried running more psi in the front, my front is always lower.
And TechX, you think 34 is high for street? I usually wont go lower than around 30 but then again I only ride street.

Guys this was 100% STREET riding, i tough my pressure was on the lower side for the street, but this is agressive riding for sure!

When i commute i usually run 34 front and 36-38 rear HOT , when i hit the twisties i lower to 32 front-34 rear HOT and the bike really feel planted to the ground, i never experienced any slippage feel but the tc do kick in a lot but its all fine in term of feeling.

i was just concerned about the blueish, so for the street do you still suggest to lower my rear a little like 32 front-32 rear hot ?

thanks !

I run 32f and 32b due to a very nice Cali. weather but I'll go to 30f and 30b when the weather hits 90 degree and up.... we average 105 in the summer time and can go as high as 115 degree.. Don't worry about the blue tint... that's just means you ran a good/hard consistence pace.

Never forget who helped you!
Never forgive who fu*ked you.
Doing a trackday is like "SEX", no matter what happens you'll want to hit it again..

For street use 32f 32r are good pressures and will work fine. 34 f and 36-38 pressures are if you have a passenger for solo riding their to high. Track day will generate more heat in the tire therefore causing the pressure to rise more than on a street ride.
