Type Pressures

Having suffered a rash of p*unctures at 120psi (high to avoid snakebites), I'm keen to know whether I need to rethink my strategy.

Views please!

    110 for me (23mm tyres; <100psi on 25mm tyres), but it depends to an extent on what you weigh. I'm around 85kg. 120 sounds bone-shakingly high.

    Can of worms! There are opinions aplenty on this one.

    I'm 80kg and run 100psi with 22/23mm tyres.

    Doesn't surprise me you have more punctures at 120psi. One Belgian race specialist I know won't pick up flatted team members if they run their tyres over 100psi! I haven't had a flat in 5,000km anyway. Last one was a shard of flint that would have got through at any road pressure.

    Hi there.

    You need to clarify the question - am I riding a race bike on good roads in the dry here?

    Cheers, Andy

    110 at the back and 100 at the front. I weigh 164lbs and I'm on 23mm Pro Race 3s.

    68kgs at present and run 110-115 front, 120-125 rear on 23mm Vredestein Fortezza Tricomps. When I first started using these tyres I did put a bit more in as they seemed soft at such pressures. They have however been fine since I gradually reduced them and give a nice supple ride.

    Same here (though I'm 154lbs).


    a serious case of small cogs

    Somewhere in the region of 110psi front and back. In the winter I prefer 100 front and back to get more grip.I am between 70-72kgs depending on how much Leffe gets disposed of at the weekend.

    I have pro-race 3 at the front and pro-race 2 at the back. Grippy as chuff.

    I did run 100-110 last month but found that a bit soft.

    I go with the views of shazz.

    It's a traction over a p******e argument, though I would rather err on the side of safety.
    Common sense in an uncommon degree is what the world calls wisdom

    Another vote for 100 front, 110 rear
    (I'm ca 75kg)

    But In the wet, I'll drop them 10-15psi


    At the WRC a couple of weeks ago, there were three cattlegrids, one was smooth but I hit the other two hard because the first rung obviously projected - one was at the bottom of a dip, the sort you zoom down to get momentum up the other side, so I hit it hard and fast.
    There were people busily fixing p*nct*res just after these two cattlegrids - I assume they were running low pressures and had snakebites.

    I ride continetal gp4000s tyres at 100 psi front and rear (day-to-day) and i weigh about 105kgs....so i am a fatty. It works out fine for me. 120psi day-to-day is pretty high.

    only once ever gone up to 120 on the road. It took my backside a week to recover!

    Hi there.

    Ok then, today I had 110psi in my Pro Race 2 clinchers, whilst I had 140psi in my tubs when I raced last weekend.

    Cheers, Andy
