Tyre Pressure - General use/deflating

[Furkz]

i filled my tyres up about 2 weeks ago and rode about 45 miles and today i went to check the pressures and back was 20psi less and front 10psi less... i do press the valve for a sec to let out air before attaching the pump which than squirts out a little air also.

is this correct of have my tubes got issues?

Its perfectly normal for tyres to lose a few psi in a few weeks and if you've released your a little more air before pumping its even more reasonable. I find my schrader valves don't lose much but the presta valves on my other bikes do. fwiw, I don't let air out before pumping the schrader valve but do with the presta valves.

I check my tyre pressures before every ride

I check my tyre pressures before every ride

and? is there much difference

If I'm doing a longer ride then I check, so they get checked at least twice a week, they may have dropped 5 psi .

It's only a one minute job to inflate them in the garage with a track pump, why not?

 

[Furkz]

cool beans i thought my tubes were buggered

 

[chewy]

Nah, both my bikes with new tubes need topping up quite often

and? is there much difference

About 10psi difference each time.. I do it because I like to run high pressures and it leaks more over time.
It's also a good way to see if you have a slow puncture

thanks all

And if you top up with CO2, they will lose pressure quicker then if you use air.

I do mine twice a week, and they're noticeably softer by then, in the sense that I can make a very slight indent by pressing hard with my thumb rather than them being rock hard. I pump mine (skinny road tyres) to 110psi.

Are we still talking about tyres here?

i might just go out and pump up my tyres, i quite like it, i feel like im setting off some dynamite chasing road runner on occasions. active imagination is greeeat
