What kind of tire pressure are people running in these tires? I seen most that say 30/30 F/R. I would think that would be crazy low.

30/30 would most likely be track day pressures. day to day 34 would probably be a better idea
if you want the tires to last a little longer or carry a passenger etc...

I run the recommended pressure (ala the frame sticker) -- maybe a bit lower sometimes. For the durability I'm getting out of them, the grip is just wicked. I love these tires!

Personally, I wouldn't use these tires for track days -- YMMV.

AN article in UKBEG by a tyre tech/designer recommends 36 front and 42 rear.

Thats what I run and all is well.

If you do some searching around here on Badweb, you'll find a ton of info on tire pressures for handling and for maximum tire life.

If you set for handling (on the order of 30/30 or 30/28) you will have good traction, good handling but probably less than half the tire life when set to the factory recommended pressures.

The Diablo are really a better tire for MOSTLY street riding with the occasional "spirited run" or track day.

Diablo Corsa are more appropriate for a 50/50 mix of track and street.

The pressures really ought to be set depending on what type of riding you intend to do that day. Nothing wrong with dropping the pressures if you're doing a canyon run and bumping them back up for daily riding or commuting.

You'll NEVER get any recommendation from Pirelli except to run at the recommended pressures. If you go to a racetrack and talk to the Pirelli vendor, they can be VERY helpful with advice on pressures based on their experience, temperatures, weight, etc.

Sorry Jamiec, But since information is always coming out I thought I would ask for some fresh info. Over half the stuff talked about on this board was brought up years ago and yet we still have questions don't we.

38 rear 40 front

On WHICH tires?

38/40 would be like riding on wet glass if you have to turn the bike at speed.

Each and every tire has recommended pressures for tire life (manufacturer's recommendations) and for performance (race tire vendor) - same tires, different pressures.

If you are ONLY concerned about tire life and NOT about turning the bike, those may be good pressures for A PARTICULAR tire.

There are NO rules about "tire pressures" Depends on:

Manufacturer
Model/specific tire
Road Conditions
Riding Preferences/Styles

(maybe it's too early in the AM for me to be posting before coffee has kicked in)

We need another tire pressure thread.

Slaughter...I was running a low 30's in each and they were warping pretty bad.
