Here is a way to determine the optimal pressure yourself.

The manual is probably wrong, you should sell it on Ebay.

 

Who cares what a madducati guy does to his SPORT BIKE? This is a
HARLEY-DAVIDSON forum and I guess it be open to all. Is it more fun to drive a ducati than to ride a HARLEY-DAVIDSON?
PS: In my car and truck I think both'em ride better with NITROGEN and ambient temperature changes don't change the tire psi
as much as with air. NOT TO BE PREACHIN', JUST SHARING MY EXPERIANCE & OPINION.

LOL that's funny....

a tire is a tire is a tire.... it doesn't know what it's on, does it?

Actually it does... that's why sport bike tires are for sport bikes and cruiser tires are for cruisers. The Ducati guys psi measurement does not work well on cruiser type bikes... cruiser tires have different characteristics and psi is assigned differently to them.

 

You have been misinformed.

MAX means just that. Maximum pressure (not recommended pressure).

Vehicle weight plays an important role,.... that is why you have a "recommended" tire pressure on a tag in the door jamb of most cars and trucks.
The 'recommended' psi, rarely matches the 'max' psi on the tire.

 

I bet he is running Earth air. Martian air is too dry and Venus air is too humid. Mercury air is too hot.




Sorry, I couldn't resist.

 

Actually it is you that has been blinded by the light... along with thousands of Ford Explorer owners who are now dead or disabled because they followed what was printed inside the door of the car.

In addition... how does that little sticker inside the door or that little blurb inside your owners manual know what tire you are currently running on your vehicle. I am currently running Pirelli Night Dragons @ 48 psi front and 50 psi rear... my owners manual recommends 36 psi front and 36 psi rear... I'd be up **** creek if I ran at the psi's that are written in the book.

The rules have changed regarding what is the correct psi to run a tire... you should broaden your scope and update your lesson plans.

PS... the psi on the tire is max psi cold... the manufacturer knows that the tire will heat up and the psi will rise as well... doesn't change the fact that you can safely inflate the tire to max cold psi and be ok.

 

Actually there have been many changes made to torque values over the years... one recent incident is HD and the totally wrong recommended torque to the steering bearing... get my drift?

 

Sorry is correct... psi doesn't depend on where the air comes from... duh. Sorry I couldn't resist
