could be a science type question.
bike around the trails, stick it in car leave it there overnight, seemed o.k, tyres still up,
over the next day they go down,
this happened more in the summer, i put it down to being hot and melting the glue on the patches the leeches ones that you just peel and stick,
i guess im asking if pressure changes ,obviously temperature does, but it does seem odd , i dont recall this happening when left in the shed,
really sorry about the long winded question,
ps thinking of the soldiers and miners, sending love andhope.
I had my road bike in the car during the summer as I was going to ride straight from work. It was a hot day and the tyres were at the usual pressure (about 110psi) and at the end of the day when I got the bike out the rear tyre had blown off the rim I assume because it got too hot and the pressure was too high in the heat of the car? Must have made a pretty big bang!
slow puncture?
fany_lion, thats what im talkin about,
radoggair? i thought that but was like one day seemed okish the next nothin, must admit i havent looked at repairing it yet so could be huh.
Driving home from my weekend away on Sunday night, CX bike in the back of the car (as it had been for about 2hrs) and suddenly there was a hissing noise. I was stuck in traffic, turned round to look at the bike in the back and sure enough, the front had a sudden puncture! I was just sat there thinking WTF??!! 😯
Turned out the the valve had failed, no idea why and it was unrepairable so one binned tube. 🙁 Really weird for it to just suddenly go like that, especially since the bike had done 100 miles that weekend with no problems.
Mine definitely wasn't a slow puncture - the inner tube was ripped open. If I leave the bike in the car for long periods in the summer now I let most the air out the tyres.
I've had the same problem with these peel and stick patches. I thought my housemate was letting my tyres down overnight because they were fine straight after the ride but flat by the morning. It took me ages to discover what the problem was.
I found that if the hole in the inner tube is big enough the air pressure will slowly push the patch off over several hours. This doesn't happen during riding because the tyre is pushing the patch against the inner tube and preventing it from peeling off.
I found that these patches were only successful with the smallest of holes and useless on your average pinch flat. I don't use these patches any more. Hope this helps.
My bike spent two whole months in the boot of my car. Pressure went down a bit but no flats. There have been plenty of times however when tyres have been flat next morning after a ride - either epic or just out to the cash point. I think it might be bad karma.
