tire pressure on Pirelli Diablo Corsa II's

Anyone ride these tires? If so what PSI do you ride on? I'm trying to figure out the optimal setting. (mainly city riding, along with the weekend highway runs out of the city)
 
Assuming you put on the stock sizes, just set it to stock pressures. Measure when cold (ie first thing in the morning).
 
First of all....what bike?

For my Dunlops and only me on the bike (CBR), I put 34F/36R

For any type of tire question, talk directly to a tire dealer or the manufacture.

34/f 36/r seems to high IMHO.

Could go a little lower.
At Tail of the Dragon I ran 30/30

This was just me, but i ran 30/30 all the time on the street.

I find this pressure gives very good grip (specialy around lots of corners) but wears tires much faster.
 
Go for the bike manufacturer's recommendation first if you're using stock sizes.. If you want to let a bit of air out to gain some traction, just be aware that it's a lot easier to bend a rim if you're at a lower setting. Especially the front. If you're on non-stock sizes, then do whatever you want basically.
 
nikiter was running Q3's at the dragon, however most street tires use similar pressures. I acutally run a Q2 front with a rosso 2 rear. Pirelli makes Rosso 2's and Rosso Corsas, but not Corsa 2's. I'll assume you mean Rosso 2's. 32/32 for regular street riding, 30/30 for track/canyon riding. On a Q2/Q3, 30/30 will wear the tire quite a bit quicker, but on the Rosso 2 which is a harder compound, it will be less noticeable. If your aggressive, i.e. yellow/red group at the track go 30/30. If not, go 32/32. Many people run pressure much higher than this, which may increase tire life, but when you are in a corner too hot, or have sub-optimal (e.g. cold) road surface, the extra bit of contact patch can make the difference between a crash and not crashing. Saving the $40 on tire life will be a drop in the bucket.
 
thanks guys, yes they are Rosso 2's my apologies. I have been riding 32/34 and it has been great for me, i am gonna try 32/32 this week and see how it feels. I was just curious as to which was the best setting but i guess its a mix of personal preference and manufacturers recommendations. cheers
 
May I ask what would be better nitrogen filled or just regular air? I know that nitrogen are being used in racing purpose, but will it be beneficial in regular vehicles? By the way I use 30 psi both front and rear.
 
I run 78 percent nitrogen. Realistically, unless you're running CSBK, AMA, or above where you need less pressure fluctuation, we are talking within a single psi, it's a waste of time and money.
 
I found 30 low on the Corsa on the street. I ran then higher near 36. Though I normally run 32/34 for Pilot Powes; the pirellis never felt right at any pressure.
