I realize this is a topic that’s been posted about a few times, but please forgive me for adding a new thread anyway just to make sure I’m not missing something. I don’t know much at all about bicycle maintenance or modern mountain bike tires.
Every time I want to go for a ride, I have to inflate my tires. It’s been that way since I bought the bike brand new (Giant Talon 2) and continued even after confirming there were no leaks.
The same problem, albeit to a much lesser degree, occurs with my 2nd bike that uses the older style standard valves (the main bike uses the Schrader-style valves). The only variable I can think of is the temperature of my garage, which can get mighty warm here in Phoenix with air temperatures hitting 40-45 degrees C (104-113 degrees F) The bikes are hanging from a hook on the wall with no weight on the tires.
Can the extreme heat in my garage actually change the shape of the tubes/tires, thereby permanently changing the seals, causing a slow leak? If the answer is yes, is there any kind of solution?
It is a gigantic pain in the butt to have to pump up the tires before every ride, even if only 24 hours apart. I’ve never had the tires get low during a long ride, so however it’s leaking, it’s very slow.
Thanks in advance for any advice you might be able to provide.
Thanks so much for all of the thoughtful replies! I actually rode down to the bike shop yesterday with the intention of having them check my tubes, but they'd gone out of business! The leak is still happening even when I don't hang the bike, and seems to be worse in the front than the rear. The really odd part? The more I ride it, the slower the leak seems to be. That makes no sense whatsoever so I'll assume I have that wrong somehow, but that's what seems to be the case. As a short term solution I bought a portable pump to carry on the bike, but the leak is slow enough to where I don't think that's too much of a concern (getting stuck on a ride). I think I'll just try a different shop & maybe just spend a few extra bucks on some higher quality tubes.
