Oh yeah? Your race bike is in my garage and will remain fitted with continentals. Until you can consistently run sub 1:40s you are not allowed to run any other brands or there might just be an unfortunate spontaneous fire.Originally Posted by DBKromz

How do you know if you're running the optimal pressure though? I was running consistent 32F/28R on a set of Pirelli Dragon Supercorsas and the seemed to be hooking up very well for times in the low 1:3x range.
Which way should I try to go to possibly get a little more umph?
Going from track day rider to racer....as you get faster you start to out ride the tires then you need to step up from Street DOT compound like a Pilotpower to a race compound in the lower levels like a D209's or D211's...then when you drop lower into the teens you gotta step it up to the Ntec's for Example....

Very helpful! I have my first track day in a few weeks, and had no clue about what tire pressure to run with...

Chuck, you should have asked me yesterday!
Assuming you have the pressures in the preferred range(you do), the question to ask is "are they doing anything you don't want them to do?" Spinning the rear, front feeling squirmy, etc. If the answer is "no," then don't change a thing.
When you come up for your Penguin weekend, we can work with you on making sure the pressures are set in the right place.![]()

I'll let you know as soon as I can figure that out.
Yeah, as you continue to drop time, you may need to make adjustments to those pressures. During race weekends, you can swing by the garage anytime to talk/check/adjust pressures.

pretty sure Dunlop calls for 33F/23R for GPA's (same as NTEC's)

What Scottie says....... for fine tuning race tire purposes.
Where you measure the "hot" pressure is also important.
Measuring on pit lane right after a few hot lap is the place.
Testing shows that following a race a cool down lap and rolling into your pit area - they can drop +2lbs.
While this thread has all the right motivation, if you are using "race" compound - talk to the folk who supply/support that particular brand
- As this thread shows there are many variables in play. Race vs. track vs. street vs. brand vs. compound vs. dot vs. slick vs. track conditions vs. rider expertise vs. where to measure pressure vs the air or moisture content in tire (water vapor expands with temp ………………………
FOR a street rider attending a track day.
First the recommended pressures in the book assumes street riding –
streets have pot holes etc and the pressures recommended takes all that into account
- taking to the track in a known environment, it's about maximizing contact patch for the given track conditions - therefore lowering the pressures is a good thing to something like what Paul said, 30-32 front and 30-32 rear.....
BUT DON'T FORGET TO INCREASE PRESSURE BEFORE STREET RIDER AGAIN or you may damage a rim on the first pot hole rolling the tire on the rim releasing air.

I like all the Pirelli race/trackday tires around these numbers HOT
30-32 Front
27-29 Rear
I generally have to bring the pressures down after my first session or two...then they are good for the day.

Pirelli Diablo Dot race tire race tire 36 rear? (from the chart on first page)
That does not seem right if I remember correctly,

if it helps I run Dunlop slicks at 29 front and 27.5 rear on a cold day and 30.5 front and 29 rear hot on a hot day

Excuse me if this has been mentioned earlier. Bike size (Weight and Performance) can come into play.
