    Tire manufacturers don't know what type of bike the tires are going to be put on. One thing for sure is under inflated tires are much worse for the tire than over inflated.
    Under=possible cupping, uneven tread wear, sidewall deterioration. Over=harsher ride and that's about it. I've always used the bike manufacturer suggestions and adjusted
    slightly from there.

    .... errrrm, there could be more serious consequences. If an overinflated tyre doesn't get up to its working temperature (which it cant do because the walls can;t flex enough) then the rubber has less grip - quite apart from the contact patch being smaller

    I tend to agree with this. Personally I am less concerned with tyre longevity than good leaned over grip from a tyre operating at a good temperature. I ran my PR4's at about 35/36 front and 36/38 rear on my NC with excellent grip evident wet or dry. My former KTM950SM which would have been similar in stature to the NC, ran 34/34 front and rear recommended by KTM. That also had good leaned over grip. Imho 42 psi is too much pressure on the rear of an NC riding solo.

    I may be wrong but I believe the tire pressure sticker indicates 36F/42R. That's what I run in my tires (that's cold pressure).

    Would weight of rider/gear impact optimal tire pressure, especially rear? It should reasonable that the rear might be better 2-4 psi under Honda's recommended 42, but it seems that would be affected by weight.

    Until I installed tire pressure monitors on the MC I'd tend to agree that lighter riders could use 38-40 rear but read post #4 in this thread. 38-40 heats up far more than 10% indicating those pressures are a little low for me. There is no loss of grip at 42 for a 175 lb ATGATT rider - it heats up to 44 or so.

    i have come to a combo of 33 front and 40 rear

    as i weight about 130lbs

    and after the ride, the tyre warm up to 35 and 42 nicely.

    if i had 36 psi infront, it wouldnt warm to to even 1 psi of increment.

    and the grip is good even on a wet day.

    ..... But shouldn't it be heating up to 46 ?
