Tyre pressure survey

vorsprung

Please vote on the tyre pressure for your favoured commuting bike for this time of year or the one your are using at the moment

If you run different pressures front and back give the front pressure...

psi to bar conversions in the poll are very approximate, don't worry about it

Wallace1492

100PSI..... why not, nice and easy to remember.

Mr Plum

Typically between 100 and 110, but I pumped up the other day after a couple of weeks of lazyness and they'd gone down to 75!

essex-commuter

Yep, 100-110 here too, for commuting.

120 for racing, but lower that to 95 off if raining.

roger_merriman

less than 80 psi here, on a SS road bike paniers etc with 25mm marathon pluses.

the tyres have tough side walls so i run them soft. 50-60 front and 70-80 rear.

fast enough to get me over 30mph on the flat, and can handle a bit of rough.

Not sure why you're asking but surely pressure alone isn't very useful/interesting if you don't know the tyre width?

I run both at 80psi (28mm tyres).

whereas I run my 28mm at 105-110.

You would also need rider weight

My M+ have 80 as the max written on the sidewall (and it works for me) so that's what I stick to. I dare say they could take quite a bit more.

I think it's commonly accepted that width and pressure are related (i.e. that wider tyres generally require lower pressure).

Usually about 110psi in the front and 120 in the back. I like it firm, I like to feel the road beneath my wheels...

I'm sure mine say more than that, my bikes quite a way from my office so haven't time to check at mo. Are you talking 26" or proper size?

Ahh the width, it does make a difference. I just Googled my own question. 8)

5.5 on the dot. The recommended psi for my MTB slicks.

5.5 psi seems very low to me, even for wider MTB tyres.

crikey.

around 35psi (around 2.4 bar) front and back here. maybe a little less in the front.

Maxxis ADvantage 2.25" width.

although...the back is very nearly shredded, so looking to switch over to tubeless (since my rims are compatible and i have the valves, tape and fluid)....and some nice winter tyres....maybe the bonty mud x.

35psi? Jeez, you must be constantly bouncing off the rims and getting snake bites...! Even car tyres are up to 50 or 60psi aren't they? Never owned a car so not sure...

SimonLyons

I read somewhere that for some tyres (I don't know which ones) the way the value for the pressure written on the side of the tyre is worked out.
Its half the value at which the tyre is pumped up to get it to come off a rim.

vorsprung

I have 25mm Bontrager Racelite Hardcases and keep them at 8 bar
This is quite high pressure for 25mm but they seem to like it that way

Don't know.....the chart at the garage says my car tyres should be 32psi.

but....nah...it is a mountain bike though and as I say, the tyres are 2.25" wide....so an awful lot more volume than I suspect most on here use for the commute....

For me...I dont want the hassle of either:

a. a commute/city specific bike
b. changing the tyres over every other day.

and i do like to ride home the long way which means I get some daily singletrack time.

cars are normally 30psi lorries etc can have very high pressures.

mtb tyres are not only wider but plenty have beefy side walls to allow very low pressures.

I run at 30psi and thats off road so roots lumps etc at speed. some go 20psi or even lower.

SimonAH

100psi on the 24mm couriers on the fixie, 85 psi on the 35's on the CX.

Yep, low pressure for MTBs (and cars), as the tyre acts as micro suspension.

My race car runs at 24psi hot pressure (means starting them at 18psi cold) and they are road legal tyres. The pressure is all about the contact patch - pounds per square inch

Depends on the weight and size of the car but typically a family hatchback will be around the 30psi ballpark. You'd be suprised firm 35psi in an mtb tyre can be, I've only managed to pinch flat a couple of times on fast rocky descents and never on the road. Course, 35 psi in a road bike tyre on the other hand.... :P

My LBS put my new tyres on a few weeks ago and I asked what pressure, he said 100psi. Anyway a couple of months later I tested them, one was at 30psi, the other 35psi.

Needless to say they are now back at 100psi!

Stone Glider

When I collected my tourer from the man who had built it for me I asked what pressures? "about 75" was the answer. So 70 in the front and 80 in the rear, they are 28's and i check them each week. No problems, despite being a bit of a l*rd*rse.

You only checked a COUPLE OF MONTHS later and you couldn't tell the difference between 35 ish and 100 ish without a gauge? :roll:
