Tyre pressures

[dmb80]

What psi is everyone running.  I am
42 rear and 36 front.  This is what the
Mechanic said to run. Does this sound right
when is the best time to check pressures

[OzzyRob]

I usually run 32 front & 36 rear, have done for the last 20 years, went down a few PSI when I was running a motard.

Check 'em cold or as near as.

Check 'em when they're cold.

Re: the pressures it seems to be becoming a bit more variable depending on what the tyres are - make & construction.

We have typically run 32F/36R or thereabouts, when I recently changed the tyres on the 999 I was advised 36/36. The Monsters do have a more rear-weight bias which may be a factor worth considering. I also remember a discussion about those funky/wobbly tyres which were recommended to run a higher pressure because they had lighter belting (Michelin Pilot Pures?) ... these were running 40+ (42?).

Generally track pressures are lower 30/30 for example.

But I think it's like asking what is your favourite gelato.

I took the time to chat with the tyre specialist at E.C. last time I was out there .
I am running Conti sport attack 2's he told me 36/36 for my S2R
He also told me its very subjective on a road bike , they way you ride , how aggressive you are on the throttle out of the corner
and the type of road base used on  the roads you ride
He said the best way was to set a base line then go and ride a loop you know well
each lap adjust the psi up or down and find what feels right for you.

So different for the track
I'm running 26 rear 30 front cold on the yama before the eleci blankets go on.
Once hot from road or warmers they hover around 3-4 psi higher.

34F, 36R.
Pirelli Diablo Rosso Corsa's.

No real rhyme or reason, it just 'feels' right (but what the bloody heck would I know....?).

[J5]

sounds a smidge high to me

google 4psi rule

looking for 4psi rise between cold and hot  readings as a general rule

different tyres do respond differently

[dragonworld.]

98 M750 34F, 36R

03 M1000DS 35F, 36R

Cold of course running Pilot Pure on both!

  I am
42 rear and 36 front. 

Too Hard 

Good place to start the owners book
  sie 1000 / s2r/ s4rs, states

2.1 bar/ 30.5 psi front

2.2 bar/ 32 psi rear

Direct from the Ducati  Gurus them selves Shaun and George at Dmoto,   

32 psi Front being a Ducati L Twin the weight is more mid mounted, unlike an in line 4 with more weight to the front 34 psi here.

38 /40 psi  Rear

Now all of this is a waste of time unless you use a certified calibrated pressure gauge,not readily available.

I  have seen cheap gauges out buy 5 psi Not a real issue with cars as the tyres have a larger volume.

So don't be cheap on the gauge buy a decent one, or two and compare the results from them.

Imo , at the end of the day if you can keep the Tyres within  + or - 2 psi all good
