Today while patching a leak, I noticed my tube is for 25-32 tyres, and my tyre is a 35. Is that really an issue? I wasn't aware of my mismatch, and I have driven quite a lot on these wheels with no noticeable problems. Now i'm just wondering if I should keep using this tube (it has two patches now).

Edit: also, the reason I was patching it because it lost maybe half of the air in ~48 hours, so not a massive hole but still a hole. I suspect it was from a piece of glass, which I thought i saw on my tyre but now seems to have come out (I had to get to work so I had no time to patch it immediately when i noticed the leak, it kept air in well enough for my commute).

Because the rubber is being stretched, a puncture can tear open like a balloon being pinpricked. A puncture in a fitting inner tube leaks slower.

You can slow down air leakage further by sticky-taping the wheel's spoke holes airtight. It helps by letting you ride to a more comfortable place for patching after noticing you have a leak.
