it weighs 350g, 85psi, 150 tpi, folding tyre.

and

28mm road tyre, 250g, 100psi, 150 tpi, folding tyre,

25mm road tyre, 230-240g, 100-130psi, 150 tpi, folding tyre.

If i ride 35mm as fast as up to 20mph for 1 hour commuting, does it not worth risking using skinny tyre 25/28mm against crashing / skidding / no grip on traction? how about 1 hour 30mins?

    Ride whatever feels best for you, personally for a decent length commute I'd go 28 or 32mm, 35mm is going to start pushing up aero resistance.
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.

    Does 32mm look wide enough for road tyre? The last time I tried it, it is thin and less likely to roll smooth and safe on rough road.

    25mm is wide enough, so yes a 32mm certainly is, not sure what you tried or how, as a 32mm is a decent compromise tyre.

    32mm doesn't look wide to me, something like tree small branches is still a hazard to this width, and it is a road tyre for hybrid bike, especially gravel on road and corning with a piece of mind for safety.

    Only you know how and where you ride, but on any normal commute route I'd happily use a 32mm, I wouldn't use a 28mm on mine as the country roads have a very rough surface and it makes for a 'fussy'/'buzzy' ride and 25's are downright uncomfortable, but for other debris I just use the Mk1 Eyeball as some of the stuff I wouldn't ride into on my 2.25" MTB tyres.

    I use a schwalbe durano 28c for my commute. Previously I was running 25c which I found was a little harsh for commuting on.

    The 28c has a little more give to it in my opinion
    The doctor said I needed to start drinking more whiskey. Also, I’m calling myself ‘the doctor’ now

    My hunch is fast CX tyres will be well fast, and fast road slicks will be fast.

    My CX bike with a far less aero postion and racing Ralph's is within a few seconds of the fastest times on the road bike. On all 1-3 mile segments I've cared to look.
