[Closed] Is it simply a question of 'low' tyre pressures?

Is it the same tube?if so it may be weak and prone to puncture. How much pressure are you running?

tubeless or more pressure or ride lighter.

If your actually getting snakebites, i.e. two holes, one each side of the centre line then it the rim pinching the tube and more pressure is the solution. Either that or learn to ride lighter, and pick your lines better.

Are you really running 35psi ? My old pump compared to my new pump is about 15psi different. They are not really calibrated well.

Put more air in and slam into rocks less.

Trails are more dry = you ride faster when its dry.

No not the same tube.

Tried tubeless and didn't get on with it. I don't think I ride that heavy really (lighter than those I ride with and it didn't happen to them). So it must be the pressure then?

Yep definitely snakebite punctures - my lines aren't bad (Not saying that I always get the right, but ok). So again, it must be pressure?

Yep, I use a digital gauge which seems pretty accurate. But you have a point about the speed thing - maybe I am 'slamming' rocks a bit more?

****, i must be running mine too high, i was told just pump your tyres up hard, i run mine probably close to 60psi.

Next outing i will droop them down to 50psi and see how i get on. I would rather have a bit too much pressure than get punctures.

I found out by trial and error many years ago that I need at least 40+psi to stop pinch punctures with my riding style and where I ride, but it's down to the individual I suppose.

May I suggest trying it again, as it generally sorts snakebite punctures out nicely! Seems to me you might like it the 2nd time round... 😉

Oh, and knowing your pressures means sweet FA without knowing lots of other variables too. What size tyres, how heavy are you, what terrain are you riding, to name but 3... I've run tyres as narrow as 1.8" on an MTB and needed best part of 50psi in them offroad so that they didn't pinch all over the place, and I've run as wide as a 2.8" Michelin comp 32 which I eventually settled on 16psi with, but could have gone lower still easily, I was just scared of rolling it off the rim.

psi depends on your weight as well, a heavy **** like myself needs a lot of pressure, I'd imagine the lighter you are then less so... I generally stick to around 35-50psi depending on the wetness, which i'd imagine will feel solid to someone lighter..

eyee , yeah depends on your weight.... i run around 30-35psi in my tyres. but then agin im just a lightstone midget...lol 😉

i bet you are dragging the rear brake 🙂
stops the rotation and squares the edges

what frame and rear shock are you running (if you have a shock that is )
I had this very same problem many years ago with heckler and 5th element coil !!!!!!

I don't think I use my brakes that much? Just touch them every once in a while to take the edge off the speed (if needed)?

It is a Heckler, but with RP23.

I cant believe some of you are setting pressure at 30/35psi

You all must be about 3 stone

Run anything as low as 10psi here, usually 20-35psi though. Know a guy who swears by 8psi.

Tyre pressure figures don't really mean anything without knowing both rider weight and tyre volume.

I'm 12st including kit & used to run 27psi front (2.35 HR) & 30psi rear (2.1 advantage) with tubes & pinch-flatted only once in 12 months (at the same time as dinging my rim).

Now converted to tubeless & run 21psi front & 24psi rear with the same tyre combo (albeit LUST tyres). No risk of pinch-flats and a noticeable increase in grip.

Tyre pressure figures don't really mean anything without knowing both rider weight and tyre volume.

...and how the weight is distributed front/rear.

Maybe i should drop to 45psi next time out and see how i get on.

Im using 2.2 Mountain Kings, i guess iv been lucky as its not been that wet over the past few months. so i guess ridding with too high a pressure would not be as big an issue.

Anyway i need all the help i can get with low rolling resistance.

I usally run 30psi on both my bikes. Both are hardtails and the only time I up the pressure is when I put winter tyres on, as I find they run better at about 35psi.

I don't know what my pressures are, I just blow them up til they feel firm enough. I usually know within a few 100 yards if I need to let some out or put more in.

if I was to guess i'd say there was about 40psi in my read and 30-35 in the front.

I rarely get pinch flats now unless I hit something really hard by accident

I suspect its mostly a question of poor line choice 😉

Maybe you have your weight too far back on the bike? A lot of people do this, just push the bike ahead of them for everything and hence there's loads of weight on the back wheel when they hit things.

Tubeless will help but you can still easily pinch flat tubeless. I run tubeless at about 30-35psi and still occasionally get pinches.

What rims? running a narrow rim with a big tyre pinches easier too

And 8psi? Come on! Is it a bike designed for riding on sand or something? At that pressure it would just roll off the rim in the first fast corner!

LUST ardent front 20psi and crossmax 25psi rear. Roll nice and has traction for all but the steepest bits downhill. Summer setup rolls nice for summer and autumn. Crossmax is not for any wet gloop ha ha
