160 PSI

[Ajax Bay]

On the road, a 90kg bloke riding 20s would need 160psi in his back tyre or risk pinch flats. A sensible man of such physique would be riding 28s (say). @blazed may be able to share his pressures which serve him well.

I'm a husky fellow, probably not many riders more, even, muscular than me and I run my 23c's at 105PSI. Why anyone would want 130, never mind 160, is a bit of a mystery.

Does that make you the second best 200lb+ cyclist on 'chat?

These days I'm around 80kg but run my 23s at 120psi+. Like my women, I like my tyres hard and unforgiving, but they also seem to cope better with the flinty feckers that litter my local roads. It's slightly counter-intuitive, but the crap tends to ping off to the sides rather than embed itself in the rubber. Added bonus points if the projectile makes a proper "pyoooowww!" sound.

It seems a reasonable top value - most speedos go further than the car would ever likely to be driven.

But still, any excuse to post this (again)

When I was tandem racing, I knew a pair who raced on their touring tandem with the tyres inflated to 160psi. They won a few TTs.

Would four tyres, 2.2 bmx, make any difference. When inflated to 110PSI?

My car's speedo is marked to 240kph.
My bathroom scale is marked to 150kgs
I don't get to use that end of the calibration much.
Don't try and inflate a wide tyre such as 25 or 28mm to anything near. It will blow off and probably damage your rim on the process.

My cleaner used to come over on her bike which had a slow puncture. She used to ask me to top it up. Due to me needing glasses plus a dirty tire, I thought the psi on the side wall read 85 but in reality it was 65psi.

I always pumped it to 70psi but one day decided to pump to what I thought was the max. "One final push", it thought. " thatll do it".

It certainly did do it as the explosion was rather unexpected. It was a pricey German bike (2000 euros). It was her main form of transport so I offered to give her my bike while I got hers repaired.

Lovely sound isn't it, especially when the stone hits a passing car. Almost like you just took a pot-shot at em.

Those are life-changing experiences. After that, even an AK47 at full bore sounds tolerable. It is even worse on MTBs. There the explosion goes with a spray of sealant slime, often green, always sticky. In our workshop, in a matter of 8 years, we probably exploded only 5 tyres like that, but in two cases the rim got taco'd in the process. On fatter tyres the tolerances are lower and just attempting to get a tubeless conversion to seat properly can cost you your sanity for a day.

One day I might tell you guys the story of the ak47 and the saucepan.

Of course, maintenance and condition will vary your results. I thought I had a flat going downhill one day, but it was just my neighbor shooting at a stump with his Kalashnikov.

Out on Sunday with my son and my cycling buddy and there was a loud flat bang right beside us. We all looked round at each other, expecting somebody to curse and stop but all three bikes kept on trundling. I realised it must have been somebody the other side of the hedge discharging a shotgun. Last time I saw someone doing that he was standing in a field full of cows, watching a wood intently. As I cruised past I asked him: "Are you shooting cows?".

i once over-inflated an old tub that i assumed would easily take the 120psi i usually put in the back tyre. made a lovely bang, and it was then i noticed it was only rated up to 85psi
