I am puzzled by this discussion about tyre pressure. I have been always maintaining 36/33 (F/R) psi air in my Linea MJD tyres for all the four years of my ownership. I never felt or thought of a need to change that. In fact, as I haven't visited the petrol pump for about a month, I specially went there 2 days ago & topped-up the tyres from 34 to 36 and 31 to 33. Though I haven't done longer trips recently, in all my long trips earlier too, I always maintained the same pressures even when I filled nitrogen. More light please??
