    That sounds a bit much, i'm the same weight and i run less than that in my 20mm pro 3 which are clinchers.

    I'd recommend about 120/130 f/r

    Tubs go to higher pressures than clinchers - when I weighed that much, I was pretty much inflating my clinchers to the max pressure stated.

    I'm lighter now, about 75kg, and I run my track tubs at about 140 (10-11 bar generally)

    From that, I'd say you were about right where you are.

    Could be worth checking the max pressure your rims advise too !

    My mavics say 140, but my vredestein tyres had a max psi of 170.

    I think you can easily go too high on pressures though - the wheel doesnt ride as well - its bobbling around over every bit of gravel on the road.

    theres alot more of me to love!!! thanks for the tips guys..

    i have 4 spoke deep xentis pair.. i might check out to see what they say..

    the ride doesnt feel bumpy but on very bad roads it can be uncomfortable at times.. I am doing a half ironman in antwerp in july and i would say there roads are better than ours!

    tub rims don't have a max pressure, do they?

    See now that you've told us you're racing - comfort really shouldn't come in to it. Whack em up! So long as they're not completely skittering all over the road then you're fine.

    Best of luck for Antwerp.

    Fine certainly, but you're likely going slower than someone who picks an appropriate tyre pressure, rather than just a maximum.

    The tyre manufacturers probably have some good advice, it's very rare for the max to be the most appropriate pressure on regular roads.
