For gravel road , off road utilization, how much do you inflate? Question is on Varadero section, but Xtourer or other bike can answer too
I run no lower than 32 rear and 28 psi front to maintain some flexibility for mixed gravel / tarmac. Any lower you start to get severe tyres wear.
Normally I run 42 rear and 36 front.
Hääääääää
hPa N per "square kiwifoot" or what?
Did some modification

I understand that
32psi = 2.20
28psi = 1.93
42psi = 2.90
36psi = 2.50

On my crosstourer:
all day gravel (fast): 2.0 front, 2.0 rear
mixed roads: 2.2 front, 2.3 rear
sealed road (asphalt): 2.5 front, 3.0 rear
track days: 2.2 front, 2.3 rear
Nearly half of my mileage comes from driving gravel, going nowhere... I seldom do weekend trips nowadays, typically 200 - 300 blast after work.

Thumbs up for Rainer! @David.. Pls use the Metric system whillst in- or deflating.
It also depends to the make of the tire. On sand or loose gravel I devlate to 1,5
On solid gravel I take 2,0.
Paved (experiences limited to Michelin and Continental) 2,4 front, 2,7 rear.
I have real difficulty with using the metric system for tyre pressure. NZ has been metric for over 40 years but we have stuck with PSI as it is easier to use. I completely fail to understand the metric system.
Think Metric, David, think metric !!!
As I said, we've been metric since the 1970s. But we still use PSI as a measure for tyre pressures. Everything else is metric.
Looking at the figures in more detail, I think that maybe the metric pressure gauges that we have in gasoline stations do not measure "official" metric Pascals but kg of weight per square cm instead. Does anyone know?
If this were the case, the figures I provided earlier would be somewhat wrong. Better conversion figures would come from just dividing psi by 14. So 28 psi=2.0, 35 psi=2.5 and 42 psi= 3.0

Most common unit to measure is Bar, not Pascal. 1 bar is 100 kilo pascal. So you are correct but the unit is different.

May be the most common, but the right measure is Pascal.
Pascal (Pa) [N/m²] or [m
-1·kg·s
-2] is a SI derived unit and is used for normal at mechanical engineering ...

Depends which country you are in, but yes I get what the preference is for this website. Tyre pressures in Pascal won't mean a thing to me though.
Pls don´t misunderstand me.
We use here in Europe the common unit: bar.
And everybody knows what we wanna explain.
But as written in the SI the correct one should be: Pa, what Jyray has written as well.
