How long should pressure hold in my tyres?

[helston90]

Every week on my commuter I inflate to 110 psi, I then do somewhere between 50 -75 miles and by the next Sunday pressure has dropped to around 80-85 psi, is this about right?
I think it's too slow to be p*nctured and just wondered if this is what I should expect from a high pressure tyre set up?

I blow mine up once a week, start at 120 end up at around 90-100 depending on the week.

I check mine once a week in normal use and always have to top them up, but never by much.

Sounds about right IMO, maybe just check your valves are tight, long nose pliers are very handy for the task, but I don't see the loss your getting as an issue TBH.

Sounds about right to me. 20psi a week I think I lose. I generally top up once a week or before a longer ride and I seem to recall putting in anything from 10-20psi.

That's cool, I always do it weekly when commuting or just before a social ride, I just wasn't sure to what degree the loss was supposed to occur, thanks for your (prompt) help!

Depends on the make of tubes, I use schwalbe and they drop from 100 - 90 psi after a couple of weeks but Ive had conti , spesh and others that needed pumped up every day .

I have an old wheel with a tyre on that I took off a road bike I recently sorted out. The tyre is perished but was hard when I picked up the bike at the beginning of April and the tyre is still just as hard. Wether it would be if being ridden I don't know.

10psi per week is about the going rate, for butyl tubes.
