Which Tyres?

It's wheel load ed, 80 kg - > 150 psi is for one wheel.
A 80kg rider with 55/45 distribution of wheel load would need to look up 44kg and 36kg on the chart.

from the description bellow the chart a 80kg rider with 45%/55% front and rear load balance would need more or less 68psi at the front and 85psi at the rear

oops, new page didn't see daveaa's reply :p

2 months and somewhere near 1800 miles the open pave is dead :( lovely while it lasted but too many punctures now. gatorskins. they just last and last.

Apples & Oranges aka race tyre vs. self-harming commuter tat

Absolutely, I just wish puncture protection wasn't so important for my commute. :/

It's a commute, not a race. Run the heaviest, most reliable tyres you can find.

In my case, Durano Plus.

Marathon Plus would last longer but I don't like their squared off profile - the Duranos handle better.

will take a look at the Durano, grippier than gators?

I know it's not a race, but when unfortunately a long commute is pretty much all you get to ride, you want to make it as comfortable and fun as possible.

Gators will be fine, just drop the pressure a bit if you want it to last a while.

Furans Plus is almost overkill unless you like riding in the gutter predominantly.

Marathon supreme will offer best of both worlds

Schwalbe ones tubeless with sealant are supple, grippy and the sealant deals with punctures.

will read the last few pages where this seems to be discussed, but I had always been under the impression higher pressure = better protected

will wait for the pasela to die and take it from there I guess

High pressure prevents pinch flats but helps penetrative punctures occur instead as the tyre won't deform around sharp objects.

Tyre pressure should be optimised for comfort, grip, to avoid pinch flats and penetrative punctures, and this will vary with rider weight, load on bike, tyre size, rim width, tyre construction and if you are using inner tubes or not.

Anything with this number of variables is not scientific, it's a realm of voodoo ruled by Lord @edscoble

That'll also be why your Open Pave die a premature death.

Heathen.

The Scoblelord?

Fair enough! Lesson learned...

That said, I run at about 100PSI and am probably around 85KG or so with bag on. so doesn't seem obscenely high by that chart?
will back off a bit more and see how that works out for me!

I don't use gators so couldn't tell you.
I've not had any issues with Duranos that other tyres wouldn't also have, ie. I binned it once around a wet bend but I was going way too fast so I think pretty much anything would've let go.

I'm not sure they existed when I was using Marathon Plus.

I'll probably stick with Durano Plus on the commuter. I'd possibly go to Durano in summer or as a front tyre - I use them on my training TT bike, along with 28mm Rubino Pro.

Gone through a set yet? Got any idea of how long these last?

I'm heavier than you and run almost all my tyres (except the real fat ones or some race tyres) at 90psi. Then I forget to pump them up and two months later I realise I've been riding around with them at 40psi. I'm normally a smooth rider though - I will avoid potholes rather than smashing into them (except where I have no warning of them *cough*Hammersmithcough)

Avoiding potholes hasn't really been a problem. Occasional curb hopping is probably the only pinch flat fear... it's more the massive amounts unexpected glass, broken bottles etc that seems been a problem lately. - supports the over high psi theory I guess

They will last: http://tomsbiketrip.com/schwalbe-marathon-supreme-touring-tyre-review/

Then stay off the pavement.

In the road/cycle lanes where I'm finding glass tbh. Does anyone even cycle on the pavement still?

Pavement as in footpath? Most glass is on the road.

Mind you, a girl last night dropped an entire bottle of red wine on the train platform in front of me. Note to secret santa gift transporters - cardboard boxes are NOT a good idea for carrying bottles of wine in. Heavy bottle, held in by small cardboard flap = smashy smashy glassy glassy no wine for you...
