Why am I having to pump my bike tyres weekly?

[edscdk]

you live on some land thats rapidly sinking? (thus increasing air preassure)

 

[joeyjojo]

I do, on average, 200 miles a week. I don't experience a PSI drop of 10 or more, and don't need to pump my tyres weekly.

Depends on the tubes, tyres, and pressure. I pump my skinny road bike tyres to 120 psi and in a week or two they're down to 60-70. Nothing you can do about it.

Check the tyre itself for a thorn or something. Damn things were the bane of my daily commute...

 

[platypus]

Aye I ride at 120/110 psi.

 

[londonbairn]

I ride a road bike to work, slightly less mileage than platypus but nonetheless on the worst roads ever known to man (West London to City) on 700x23.

I don't experience large PSI swings in a week unless I have a slow puncture, and always check my pressure weekly, or more if I suspect if something is up. Takes a couple of weeks to see anything near 10psi

Edit: I use GP 4 Seasons tyres, continental inner tubes and RS21 wheels

I've found this to be a problem in the past with cheap tubes and dodgy valves.

Got some decent ones fitted and inflate maybe ever 4 -6 weeks.

 

[Zogger]

I used to get slow leaks and punctures all the time with my old tyres (around 2 a month on average). I tried slime and it saved a few punctures but didn't really help a great deal overall

I switched to Schwalbe Marathon Plus tyres 9 months ago and haven't had a puncture since (and saved a fortune on all the inner tubes and slime I could have been buying, and hours of my time changing tubes)

If you have Presta valves (the tall thin ones) could it be that you haven't screwed down the metal valve tip sleeve (not the plastic cap) properly ?

Your obviously too weak to pump air into the wheels, so I recommend getting on of these:

I put 110-120psi in my road tyres and they've usually dropped to ~80psi a week later. Doesn't matter what tyres I use, they've always done it. You guys who don't lose any pressure, what brand/model tubes are you using?

Same here really. I'm using some generic inners (that came with my bike from PX) and gatorskin tyres.

I'm doing way less than 200 miles per week too. Past few weeks it has been between 80 and 140.

if your bike sits without use it looses more air from what I've experianced.. i probably lose 20-30psi/month no more than that and I'm running halfords 3.99 tubes

For a very long time now I've used Michelin Pro n's Service Course and Vittoria inner tubes.

Not sure about this either. My spare sets of wheels don't lose pressure hung up on the wall.

my bmx does lose it's pressure all the time it is schrader valve tho, also my SS does the same because it's only used twice a month of that

 

[Lartyconshayo]

schwalbe marathon durano tyres 700x23 and schwalbe inner tubes.

I probably pump every 3 - 3 weeks I got to 100 psi and can have dropped 20 to 30 psi in that time depending

Similar experience to you, ill pump mine up twice a week.

Using Conti Tubes.

Due to a bad back I've not been out on my bike since October but I've been using it on the turbo trainer. Recently I've been having to pump my front tyre up daily (which isn't even used), I'm assuming it must be a faulty valve. Tubes are the ones that came with my Canyon which due to my back hasn't seen much tarmac at all.
