Mincer error.

WTF is a blow out on a MTB tyre, do you mean a puncture or a burped tyre?

Excessive lack of finesse if the latter 😆

Or tyres not suited to terrain is another cause, or too little pressure, or shit tubes, or knackered rim tape, or fecked rims, or…………

So you pinch flatted / got a snake bite?

If so, use the common phrase, not something associated with a motor vehicle tyre overheating and typically delaminating and then blowing up/splitting due to pressure in the tyre being too low.

Could be caused by pressure being too low, tyres not fit for purpose i.e. skinny XC tyres used for bowling through rock gardens, crap tubes, heavy riding technique – clipping square edges a lot.

Any of the above, pretty much as my initial post genius 😉

I reckon the last one is a pinch where the side wall on one side has compressed, maybe under heavy cornering.

If there's no damage to the outside of the tyre, it's either too low pressure or shite/knackered tubes.

30psi

throw away the rubbish spesh tires, they're like riding round with crepe paper tyres. Thin sidewalls, and lots of pinch flats.

Get some Maxxis, minion/highroller if only for the back, and deal with the extra weight. You'll see lots less pinch flatting, and can run low-ish pressures. Not to mention being able to go round corners almost as fast as along the straight bits.

Bloody hell I thought I ran high pressures 😆

Ahh thats better 😆 😳

I used to get a LOT of rear snakebites, tried normal tyres tubless and shredded them. I switched to UST tyre on my xc bike run at 40psi, almost never pinch that now (but still occasionally)

On my burlier bike I started using big but light 'normal' tyres with a DH tube, again at 40ish psi, but still flatted once every ride or so. Now I'm using maxxis dual plys run tubeless, about the same weight as previous combo but so far looking good. (big xc tyre 7-800g DH tube 400g, dual ply 2.3 1100-1200g)

Both are FS on the rear wheel, front wheels and on a hardtail I don't flat so much. I just tend to hit rocky lines hard when on a squishy bike and my tyres suffer for it.

is there damage in the inside of the tyre, and when you mend punctures do you grate some chalk over the patch?

I do not write things that I would not say to someones face.

I usually run tyres at 60psi so I don't get pinch punctures

Go tubeless.
'Round these parts it's a given or else you hold the group ride up, not to mention the messing about on your own rides. One guy had 6 punctures one ride about 2 months ago. Now tubeless and carefree.
Job done. It really is that simple.
