None taken , it's a valid question.
If you look at the label it says 'Recommended Pressures'. Which suggests to me that it's not a hard or fast setting, it's a 'r e c o m m e n d a t i o n' .
There's a wild variation in tyre pressure pumps and gauges too. So are you actually putting in 32psi? Is your tyre guage calibrated to a UKAS standards? I doubt it.
Are you measuring when the tyres are cold too? After a drive then pressure rises.
I suggest, and I mean suggest you have your own gauge, inflate the tyres to what your guage says is 32psi and go for a drive , if the feels good then it is. But try 33, 34 or even 30psi and see if you notice a difference. I used to do this on my Kawasakis, and the difference was light and day.
