What does everyone run as far as tire pressure? factory spec? Something you've found that makes the bike feel or handle better? Summer /winter?
Hot / colder days tracks?

Michelin Powers I run at 33fr, 35rear, these Supercorsa's MV says 33/33, Pirelli's web site says 36/39? but I've not had a real dry test of them at the higher pressures, they felt hard enough as in harsh at the lower pressure, reckon i'm going back to Michelins for the summer

 

[psst!!!...]

on Michelin´s used 33 front and 35 rear.
on pirellis supercorsa use 35/39 front/rear. I dont imagine using lower pressures with these tyres, they will not last on Highways for example.
Will try corsaIII with same pressure 35/39, but only in January.

Anyone ever put Nitrogen or CO2 in their tyres instead of just air? :idea:

only in my bmw tires
my friends swear by it

an extra 2-3K miles/tire on their BMW K1200Ss
they all insist that is true

there IS something to it
afterall, every major racing organization uses it exclusively
NASCAR
F1
Indy
Cart

etc...

CO2 is not a good idea. It works in a pinch when you need roadside inflation and can get it from a small cartridge. The probelm is that with CO2 you wou'll lose pressure fairly quickly - the molecules find their way out.
Some racers advocate nitrogen for it's dryness and stability. You'll get a different pressure rise (from temperature) with it though.

SuperCorsa Pro SC1 & 2 (front/back) 31/30 for track riding and for road riding 36/33.

I have never heard of using co2, we used to use n2 in the race car tyres, it does'nt make a great difference to hot or cold running pressures, but what it does do with proper purging is it guarantee's that you will have no moisture in the tyre, moisture in a race tyre is the last thing you need, with race tyres running at 100c and sometimes over the water expansion and subsequent pressue increase is not desireable

man, you guys are really smart and informed. you never know how detailed a response you will get around here. :king:

Right. I expected someone to call me out with references to Boyle's law or Laussac or some such that proves all gases expand uniformly with respect to temperature rise. It's the moisture content that causes the difference - that's why I mentioned N2's dryness and stability.

Damn...your too quick, worked in gas liquifraction for years and waited years for this opportunity!!! :laughing: :laughing:
