Quickly: what tire pressures do you use at 30' or less?
Help Support Ducati Forum:
Just read some guys at track using 28f/26f
Helps them to heat up faster....
Not sure if I'd loose too much sidewall deflectivity at these pressure as it should heat up a bit quicker
It's 28 now so ill find out and report back later today just for an index

FWIW - had this conversation with Jim from Catalyst Reaction recently and his thoughts were if your riding street in cold temps - in the 30's - you should put a couple of psi more in tires as cold asphalt will actually suck heat from tires and drop pressure.

Norcal is having some strange weather. Early morning it's in the 30's but by 2pm we're up to high 60's / low 70's!!! So start cold and finish warm. Heated jacket works wonders!!
New York area street riding, you should be ok with 32/32....up or down a little wont hurt you to try for your own preference - if you find that you can't feel the difference between 2 or more lbs then stick with 32/32 or close too it...not too much lower if your street riding, as pavement conditions, pot holes, and frost heaves could easily damage the rim
On the track, where conditions (temperatures, tarmac) are fairly consistent, known (amongst those frequenting the track) lower cold setting pressures are used to build up heat (and pressures 2 to 4psi) putting whatever tire being used up to correct riding pressures for the given tire at the given track on the given day - most tire manufacturers will state what pressures to use to start off with on track days as a general guide, but seeking out numbers from fellow track guys or track day organizers would be your best bet for starting off
By the way, it is generally not acceptable to bleed off a hot tire to a set pressure.......(i my have just started a thread war....) but thats my opinion
Caveat Emptor however....trust then verify (if your racing the guy telling you what pressures to use)

Excellent advise
Found out why I was so loose...
The arctic vortex we recently experienced had reduced my tires 10 pounds each to 20F and 19R !!!
It was o cold that week and I assumed my pressures were the same after the temps climbed back up to the 30's.
Man was I wrong!!
Took a ride yesterday, (who really winterized their bikes when a possible 35-40 degree day can pop up right before a snow storm?)
Had the pressures back to 31/30 and all was well again. Ripped a quick 75 mile sprint and
Got sad again today as the snow piles up all over again!!
