Just curious as to what pressures people are running for street riding? I'm in Socal (warm climate), weigh 175 lbs., and run 32/33 in both front and rear.

i live in so. cal and weigh 175 lbs.

on the street... with the BT012... i run 36 in front and 42 in the rear (whatever Honda recommends).

for track... i run anywhere from 29 to 31 front and rear.

word... nick - mri

road 34 front 40 rear 208's just my .02

i run my tires at 33 (208ZRs) and the seem to heat up alot when i ride moderatly hard. i have some blueing on the edges after i come back from palomar, but they stick alot better than at the stock pressures. i'm trying to experement with raising a couple psi and see if it doesn't heat the tires quite so much, but still gets good grip. i'll get back to you, just make sure you check the pressure at the same time (cold) everytime. if you ride then check it the air heats up inside the tire, expands and will give you a higher reading than when the tire is cold.

The bike is used for fun rides only (no commuting, no rain) and I really don't care about mileage or tire life. I currently have the OEM Michelins, but will replace these with either the Pirelli or Metzeler based on reviews and trying something different.

I am just wondering what others run for pressure as the recommended pressures (especially the rear) seem to be too high. Also what is the reasoning for running higher pressure in the rear?

With 36 psi + in the rear, I notice that at close to threshold breaking, especially on a slight down hill, the back-end starts talking to me, but is fine at 33 psi. under the identical conditions. I do use both front and rear brakes for heavy braking, and have a good feel and am comfortable with using the rear.

I guess I was just curious as to what all the hot-shoes, and very experienced Sportbike riders like to run, for my learning purposes. The karts were very sensitive to a 1 psi difference.

I ususally set them stock but no less than 2lbs lower for the street.

 

[FOX]

well i suck so i'll bow out of this conversation, except that the rear pressure is 42 in the back so you can safely carry a passenger

 

[daleCarlsbad]

Hey FOX whats up with the "i suck" comment? :shock:

It sounds like you are going through the same process as I am....trying to find an optimum tire pressure.

Some guy asks if he should "leave his girl friend".....and gets 60 answers!!!! :roll:

I was just hoping to get feed back like that and be able to start seeing a pattern.

36-38psi on the street, 30-32psi on the track. Pirelli Diablo Corsas.

 

[CBRBob]

Funny how the Diablo Corsas run a higher temp on the track...

 

[CVRider]

With th BT012... I run 36 in front and 42 in the rear (whatever Honda recommends). 75% of the time solo other 25% with Passenger.

 

[vdub18t]

Honda recommended on street (929)

For the track (RR)---(outside temp: over 60 degress):
30 front Pirelli SuperCorsa

30 rear Pirelli SuperCorsa

(outside temp: under 60 degress):
34 front Pirelli SuperCorsa

34 rear Pirelli SuperCorsa

 

[corner worker]

For the track (RR)---(outside temp: over 60 degress):
30 front Pirelli SuperCorsa

30 rear Pirelli SuperCorsa

(outside temp: under 60 degress):
34 front Pirelli SuperCorsa

34 rear Pirelli SuperCorsa

Its late on a friday afternoon so I might not be thinking straight, but wouldn't you want lower pressure in lower temps to heat the rubber up quicker and improve grip?

And CBRBob I would think that all tires run a little hotter at the track being that they are being pushed harder and run at lower psi. Agin though its late friday so wtf do I know?

 

[vdub18t]

It's like this here: The optimum operating pressure for a race tire (Pirelli SuperCorsa in this case) is around 35-36 psi. When it's warm out, the tires come up to this temp quite easily (warm weather, warm track).

When it is cold out, the tires do not tend to heat up quite as easily as in warm weather (no doubt). So to get to the optimum psi you need to have the tire close to the optimum psi to begin with.

I used to think the same as you until I kept cold tearing tires (too much flex in the carcass...contact patch size not cconsistent) after 5-7 laps. Then when I asked the Pirelli rep/sales guy at the track. He set me straight.

Thanks for the info. If 35-36 psi is optimal, where do you start off (cold tire psi) so that it gets to those numbers at temperature?

 

[vdub18t]

Warm weather / warm track: 30 psi

Cold Weather / cold track: 34 psi


For street riding, I simply check the pressures cold (before you ride) and then adjust to the recommended factory settings (e.g. 929 - 36 front 42 rear)

 

[2X80MPH]

For canyon riding..... in the summer, I run 29-31. Remember, you will gain as much as 5# pressure (warm weather) in a very short time!
