Is it me or do road tyres keep going down. It seems each time I set off for a ride I need to pump up the tyres. I also get a lot of punctures. Does 100psi leak out through the skinny inner tubes?
Is all this normal?
road tyres keep going down
bit like this place?
ba booom tisshhh.....
Barely ever pump up my tyres. Although by the time I do, they've gone down to about 60psi ish.
I always check tyre pressure before a ride (except commuting, when I check it once a week). I always check MTB, cross and track (especially) pressures. That's normal isn't it?
They can lose some pressure, but not much, through butyl tubes, but loads more if you're using latex tubes.
I reckon I lose 20+psi a week in my roadie tyres. Normally inflate to 110psi. Check them beginning of each week (for commuting) or before a proper ride.
These are new butyl tubes with no patches.
What tubes are you using, if latex, yes they leak loads, if standard butyl, these lead at a slower rate.
What are you filling them with, CO2 (i.e. from cartridges) leaks much quicker than regular air.
How long between rides, all tubes will loose pressure, and the higher the start pressure is, the more noticeable. If they are going totally flat, you probably have a slow puncture or leaking valve, if going from say 100psi down to 80psi over a few days, that's pretty normal.
When road riding, would expect to top up the tires if had had more than a few days between rides.
